Prosopagnosia
The inability to recognize a familiar face or to learn to recognize new faces. This visual agnosia is most often associated with lesions involving the junctional regions between the temporal and occipital lobes. The majority of cases are associated with bilateral lesions, however unilateral damage to the right occipito-temporal cortex has also been associated with this condition. (From Cortex 1995 Jun;31(2):317-29)
Agnosia
Loss of the ability to comprehend the meaning or recognize the importance of various forms of stimulation that cannot be attributed to impairment of a primary sensory modality. Tactile agnosia is characterized by an inability to perceive the shape and nature of an object by touch alone, despite unimpaired sensation to light touch, position, and other primary sensory modalities.

Cerebrum
Derived from TELENCEPHALON, cerebrum is composed of a right and a left hemisphere. Each contains an outer cerebral cortex and a subcortical basal ganglia. The cerebrum includes all parts within the skull except the MEDULLA OBLONGATA, the PONS, and the CEREBELLUM. Cerebral functions include sensorimotor, emotional, and intellectual activities.
Functional delineation of the human occipito-temporal areas related to face and scene processing. A PET study. (1/65)
By measuring regional cerebral blood flow using PET, we delineated the roles of the occipito-temporal regions activated by faces and scenes. We asked right-handed normal subjects to perform three tasks using facial images as visual stimuli: in the face familiar/unfamiliar discrimination (FF) task, they discriminated the faces of their friends and associates from unfamiliar ones; in the face direction discrimination (FD) task, they discriminated the direction of each unfamiliar face; in the dot location discrimination (DL) task, they discriminated the location of a red dot on a scrambled face. The activity in each task was compared with that in the control fixation (CF) task, in which they fixated on the centre of a display without visual stimuli. The DL task activated the occipital cortices and posterior fusiform gyri bilaterally. During the FD task, the activation extended anteriorly in the right fusiform gyrus and laterally to the right inferior temporal cortex. The FF task further activated the right temporal pole. To examine whether the activation due to faces was face-specific, we used a scene familiar/unfamiliar discrimination (SF) task, in which the subjects discriminated familiar scenes from unfamiliar ones. Our results suggest that (i) the occipital cortices and posterior fusiform gyri non-selectively respond to faces, scrambled faces and scenes, and are involved mainly in the extraction of physical features of complex visual images; (ii) the right inferior temporal/fusiform gyrus responds selectively to faces but not to non-face stimuli and is involved in the visual processing related to face perception, whereas the bilateral parahippocampal gyri and parieto-occipital junctions respond selectively to scenes and are involved in processing related to scene perception; and (iii) the right temporal pole is activated during the discrimination of familiar faces and scenes from unfamiliar ones, and is probably involved in the recognition of familiar objects. (+info)Selective sparing of face learning in a global amnesic patient. (2/65)
OBJECTIVE: To test the hypothesis that visual memory for faces can be dissociated from visual memory for topographical material. METHOD: A patient who developed a global amnesic syndrome after acute carbon monoxide poisoning is described. A neuroradiological examination documented severe bilateral atrophy of the hippocampi. RESULTS: Despite a severe anterograde memory disorder involving verbal information, abstract figures, concrete objects, topographical scenes, and spatial information, the patient was still able to learn previously unknown human faces at a normal (and, in some cases, at a higher) rate. CONCLUSIONS: Together with previous neuropsychological evidence documenting selective sparing of topographical learning in otherwise amnesic patients, this case is indicative of the fact that the neural circuits involved in face recognition are distinct from those involved in the recognition of other visuoperceptual material (for example, topographical scenes). (+info)Face recognition in age related macular degeneration: perceived disability, measured disability, and performance with a bioptic device. (3/65)
AIMS: (1) To explore the relation between performance on tasks of familiar face recognition (FFR) and face expression difference discrimination (FED) with both perceived disability in face recognition and clinical measures of visual function in subjects with age related macular degeneration (AMD). (2) To quantify the gain in performance for face recognition tasks when subjects use a bioptic telescopic low vision device. METHODS: 30 subjects with AMD (age range 66-90 years; visual acuity 0.4-1.4 logMAR) were recruited for the study. Perceived (self rated) disability in face recognition was assessed by an eight item questionnaire covering a range of issues relating to face recognition. Visual functions measured were distance visual acuity (ETDRS logMAR charts), continuous text reading acuity (MNRead charts), contrast sensitivity (Pelli-Robson chart), and colour vision (large panel D-15). In the FFR task, images of famous people had to be identified. FED was assessed by a forced choice test where subjects had to decide which one of four images showed a different facial expression. These tasks were repeated with subjects using a bioptic device. RESULTS: Overall perceived disability in face recognition did not correlate with performance on either task, although a specific item on difficulty recognising familiar faces did correlate with FFR (r = 0.49, p<0.05). FFR performance was most closely related to distance acuity (r = -0.69, p<0.001), while FED performance was most closely related to continuous text reading acuity (r = -0.79, p<0.001). In multiple regression, neither contrast sensitivity nor colour vision significantly increased the explained variance. When using a bioptic telescope, FFR performance improved in 86% of subjects (median gain = 49%; p<0.001), while FED performance increased in 79% of subjects (median gain = 50%; p<0.01). CONCLUSION: Distance and reading visual acuity are closely associated with measured task performance in FFR and FED. A bioptic low vision device can offer a significant improvement in performance for face recognition tasks, and may be useful in reducing the handicap associated with this disability. There is, however, little evidence for a correlation between self rated difficulty in face recognition and measured performance for either task. Further work is needed to explore the complex relation between the perception of disability and measured performance. (+info)Slowly progressive defect in recognition of familiar people in a patient with right anterior temporal atrophy. (4/65)
We report the case of a patient (C.O.) who showed a selective defect in the recognition of familiar people, with very mild disease progression during a period of 30 months resulting from focal atrophy of the right temporal lobe. On formal neuropsychological testing, C.O. obtained high scores on tests of general intelligence, episodic memory, language, executive functions, selective attention, visual recognition and visual-spatial abilities. On more specific tasks of familiar and unfamiliar face recognition, C.O. scored above the controls' means on perceptual tests, but obtained highly pathological results on amnesic-associative tests. His disorder of recognition of familiar people was not due to loss of person-specific information, since he obtained highly abnormal naming scores when presented with photographs of famous people but borderline or mildly abnormal scores in a tasks in which he had to name celebrities from verbal definitions. On the other hand, C.O.'s recognition disorder could not be considered to be a form of 'associative prosopagnosia' since a similar defect was observed when he was requested to access information about famous persons through their voice rather than their face. Two alternative interpretations are advanced to explain C.O.'s inability to access his relatively spared person-specific knowledge not only through the person's face but also through the person's voice. The first hypothesis is that, before accessing the person-specific information, unimodal recognition channels must converge into a multimodal, non-verbal person-recognition system and that the right anterior temporal cortices play a crucial role in this integrative activity. The second hypothesis is that the face-recognition units have privileged access to person-specific semantic knowledge and that other recognition subsystems require coactivation of the face-recognition units in order to access person-specific semantic information. (+info)Hyperfamiliarity for unknown faces after left lateral temporo-occipital venous infarction: a double dissociation with prosopagnosia. (5/65)
Right hemisphere dominance in face processing is well established and unilateral right inferior temporo-occipital damage can result in prosopagnosia. Here, we describe a 21-year-old right-handed woman with acute impairment in face recognition that selectively concerned unfamiliar faces, following a focal left lateral temporo-occipital venous infarct. She was severely impaired in discerning that unknown people seen in everyday life were unfamiliar, although she had no difficulty recognizing familiar people. Thus, she had no prosopagnosia, but abnormal 'hyperfamiliarity' for unknown faces. Her difficulty was not accompanied by delusions or deficits in discrimination, identification or memory for faces. Standard neuropsychological testing showed that her recognition of familiar faces was entirely normal. By contrast, her sense of personally knowing faces was severely impaired when unknown faces evoked weak signals of familiarity based on spurious cues, to the extent that she would misattribute fame to faces that were unknown but to which she had been incidentally exposed on a prior occasion. Priming experiments also revealed that, unlike normal subjects, she made familiarity judgements without accessing semantic identity representations. Moreover, in face recognition tests, she generally showed bias in that she relied more on right-hemisphere strategies to identify global traits and less on left-hemisphere processes compared with healthy subjects. This case provides novel evidence for a differential contribution of the two hemispheres to face recognition. Hyperfamiliarity for unknown faces might arise from an imbalance between reciprocal hemispheric functions in face recognition, with relative hypoactivation of left hemisphere processes but hyperactivation of right-hemisphere processes for retrieving stored associations about people, linking seen faces to representations of affective and personal relevance. Hence, abnormal bias in attributing some personal meaning to unknown faces could be evoked by spurious signals of familiarity based on irrelevant affective associations in the right hemisphere. (+info)A network of occipito-temporal face-sensitive areas besides the right middle fusiform gyrus is necessary for normal face processing. (6/65)
Neuroimaging studies have identified at least two bilateral areas of the visual extrastriate cortex that respond more to pictures of faces than objects in normal human subjects in the middle fusiform gyrus [the 'fusiform face area' (FFA)] and, more posteriorly, in the inferior occipital cortex ['occipital face area' (OFA)], with a right hemisphere dominance. However, it is not yet clear how these regions interact which each other and whether they are all necessary for normal face perception. It has been proposed that the right hemisphere FFA acts as an isolated ('modular') processing system for faces or that this region receives its face-sensitive inputs from the OFA in a feedforward hierarchical model of face processing. To test these proposals, we report a detailed neuropsychological investigation combined with a neuroimaging study of a patient presenting a deficit restricted to face perception, consecutive to bilateral occipito-temporal lesions. Due to the asymmetry of the lesions, the left middle fusiform gyrus and the right inferior occipital cortex were damaged but the right middle fusiform gyrus was structurally intact. Using functional MRI, we disclosed a normal activation of the right FFA in response to faces in the patient despite the absence of any feedforward inputs from the right OFA, located in a damaged area of cortex. Together, these findings show that the integrity of the right OFA is necessary for normal face perception and suggest that the face-sensitive responses observed at this level in normal subjects may arise from feedback connections from the right FFA. In agreement with the current literature on the anatomical basis of prosopagnosia, it is suggested that the FFA and OFA in the right hemisphere and their re-entrant integration are necessary for normal face processing. (+info)Impaired configurational processing in a case of progressive prosopagnosia associated with predominant right temporal lobe atrophy. (7/65)
F.G., a 71-year-old right-handed man, presented with a slowly progressive deterioration in his ability to recognize faces of familiar and famous persons, contrasting with the relative preservation of other cognitive domains. His primary face perception skills were intact. Along with his face-recognition deficit, F.G. also exhibited a mild visual agnosia. A more detailed analysis of his performance on visuoperceptual tests revealed a selective deficit in retrieving the configurational representation of complex visual entities and an over-reliance on analysing individual features. Quantitative volumetric measurements of his temporal lobe structures showed a prevalent atrophy of the right fusiform gyrus and parahippocampal cortex. The results of the present study suggest that a right temporal variant of frontotemporal lobar degeneration may be characterized over a period of several years by an impaired configurational processing of visually complex entities in the absence of any semantic deficit. (+info)A modulatory role for facial expressions in prosopagnosia. (8/65)
Brain-damaged patients experience difficulties in recognizing a face (prosopagnosics), but they can still recognize its expression. The dissociation between these two face-related skills has served as a keystone of models of face processing. We now report that the presence of a facial expression can influence face identification. For normal viewers, the presence of a facial expression influences performance negatively, whereas for prosopagnosic patients, it improves performance dramatically. Accordingly, although prosopagnosic patients show a failure to process the facial configuration in the interest of face identification, that ability returns when the face shows an emotional expression. Accompanying brain-imaging results indicate activation in brain areas (amygdala, superior temporal sulcus, parietal cortex) outside the occipitotemporal areas normally activated for face identification and lesioned in these patients. This finding suggests a modulatory role of these areas in face identification that is independent of occipitotemporal face areas. (+info)Prosopagnosia is a neurological disorder characterized by the inability to recognize familiar faces, often resulting from damage to specific regions in the brain involved in facial perception.
Prosopagnosia is a neurological disorder characterized by the inability to recognize or remember faces, even those of familiar people such as family members and friends. This condition often results from brain damage, particularly to the fusiform gyrus area located in the temporal lobe, which is responsible for facial recognition and memory.
Individuals with prosopagnosia may have difficulty distinguishing between faces, sometimes even mistaking their own reflection or confusing family members with strangers. However, they can still recognize people through other means, such as voice, hairstyle, clothing, or gait. Prosopagnosia can be congenital (present at birth) or acquired due to brain injury or disease.
There are two main types of prosopagnosia: developmental (or congenital) and acquired. Developmental prosopagnosia is present from birth and tends to run in families, suggesting a genetic component. Acquired prosopagnosia occurs after brain damage due to stroke, trauma, or degenerative diseases like dementia.
Prosopagnosia can significantly impact social interactions and relationships, causing distress and isolation for those affected. Currently, there is no cure for this condition; however, various strategies and techniques can help individuals with prosopagnosia cope and improve their face recognition abilities.
Agnosia is a higher cognitive disorder characterized by an impaired ability to recognize and interpret sensory stimuli despite intact sensory pathways and normal intellectual function.
Agnosia is a medical term that refers to the inability to recognize or comprehend the meaning or significance of sensory stimuli, even though the specific senses themselves are intact. It is a higher-level cognitive disorder, caused by damage to certain areas of the brain that are responsible for processing and interpreting information from our senses.
There are different types of agnosia, depending on which sense is affected:
* Visual agnosia: The inability to recognize or identify objects, faces, or shapes based on visual input.
* Auditory agnosia: The inability to understand spoken language or recognize sounds, even though hearing is intact.
* Tactile agnosia: The inability to recognize objects by touch, despite normal tactile sensation.
* Olfactory and gustatory agnosia: The inability to identify smells or tastes, respectively, even though the senses of smell and taste are functioning normally.
Agnosia can result from various causes, including stroke, brain injury, infection, degenerative diseases, or tumors that damage specific areas of the brain involved in sensory processing and interpretation. Treatment for agnosia typically focuses on rehabilitation and compensation strategies to help individuals adapt to their deficits and improve their quality of life.
In anatomy, the face is the front part of the head that includes the eyes, nose, mouth, and cheeks, and serves as the main interface with the external world for expression, sight, smell, taste, and hearing.
In medical terms, the face refers to the front part of the head that is distinguished by the presence of the eyes, nose, and mouth. It includes the bones of the skull (frontal bone, maxilla, zygoma, nasal bones, lacrimal bones, palatine bones, inferior nasal conchae, and mandible), muscles, nerves, blood vessels, skin, and other soft tissues. The face plays a crucial role in various functions such as breathing, eating, drinking, speaking, seeing, smelling, and expressing emotions. It also serves as an important identifier for individuals, allowing them to be recognized by others.
Visual pattern recognition is the cognitive process of perceiving and interpreting visual stimuli to identify specific configurations or arrangements of elements that match previously learned templates or concepts.
Visual pattern recognition is the ability to identify and interpret patterns in visual information. In a medical context, it often refers to the process by which healthcare professionals recognize and diagnose medical conditions based on visible signs or symptoms. This can involve recognizing the characteristic appearance of a rash, wound, or other physical feature associated with a particular disease or condition. It may also involve recognizing patterns in medical images such as X-rays, CT scans, or MRIs.
In the field of radiology, for example, visual pattern recognition is a critical skill. Radiologists are trained to recognize the typical appearances of various diseases and conditions in medical images. This allows them to make accurate diagnoses based on the patterns they see. Similarly, dermatologists use visual pattern recognition to identify skin abnormalities and diseases based on the appearance of rashes, lesions, or other skin changes.
Overall, visual pattern recognition is an essential skill in many areas of medicine, allowing healthcare professionals to quickly and accurately diagnose medical conditions based on visible signs and symptoms.
The temporal lobe is the lower lateral region of each cerebral hemisphere, primarily involved in auditory processing, memory, and emotion due to its major components: the primary auditory cortex, hippocampus, and amygdala.
The temporal lobe is one of the four main lobes of the cerebral cortex in the brain, located on each side of the head roughly level with the ears. It plays a major role in auditory processing, memory, and emotion. The temporal lobe contains several key structures including the primary auditory cortex, which is responsible for analyzing sounds, and the hippocampus, which is crucial for forming new memories. Damage to the temporal lobe can result in various neurological symptoms such as hearing loss, memory impairment, and changes in emotional behavior.
The occipital lobe is the neuroanatomical region in the backmost part of the brain's cerebral cortex, primarily responsible for visual processing and identification of visual stimuli.
The occipital lobe is the portion of the cerebral cortex that lies at the back of the brain (posteriorly) and is primarily involved in visual processing. It contains areas that are responsible for the interpretation and integration of visual stimuli, including color, form, movement, and recognition of objects. The occipital lobe is divided into several regions, such as the primary visual cortex (V1), secondary visual cortex (V2 to V5), and the visual association cortex, which work together to process different aspects of visual information. Damage to the occipital lobe can lead to various visual deficits, including blindness or partial loss of vision, known as a visual field cut.
The cerebrum is the largest part of the brain, located in the frontal portion of the skull, and it is responsible for higher brain functions, including consciousness, thought, memory, perception, and motor function.
The cerebrum is the largest part of the brain, located in the frontal part of the skull. It is divided into two hemispheres, right and left, which are connected by a band of nerve fibers called the corpus callosum. The cerebrum is responsible for higher cognitive functions such as thinking, learning, memory, language, perception, and consciousness.
The outer layer of the cerebrum is called the cerebral cortex, which is made up of gray matter containing billions of neurons. This region is responsible for processing sensory information, generating motor commands, and performing higher-level cognitive functions. The cerebrum also contains several subcortical structures such as the thalamus, hypothalamus, hippocampus, and amygdala, which play important roles in various brain functions.
Damage to different parts of the cerebrum can result in a range of neurological symptoms, depending on the location and severity of the injury. For example, damage to the left hemisphere may affect language function, while damage to the right hemisphere may affect spatial perception and visual-spatial skills.
Neuropsychological tests are standardized, validated measures used to evaluate various cognitive abilities and psychological processes, allowing for the identification and quantification of strengths and weaknesses in relation to brain function and dysfunction.
Neuropsychological tests are a type of psychological assessment that measures cognitive functions, such as attention, memory, language, problem-solving, and perception. These tests are used to help diagnose and understand the cognitive impact of neurological conditions, including dementia, traumatic brain injury, stroke, Parkinson's disease, and other disorders that affect the brain.
The tests are typically administered by a trained neuropsychologist and can take several hours to complete. They may involve paper-and-pencil tasks, computerized tasks, or interactive activities. The results of the tests are compared to normative data to help identify any areas of cognitive weakness or strength.
Neuropsychological testing can provide valuable information for treatment planning, rehabilitation, and assessing response to treatment. It can also be used in research to better understand the neural basis of cognition and the impact of neurological conditions on cognitive function.
