Cortical deafness to dissonance. (1/30)
Ordinary listeners, including infants, easily distinguish consonant from dissonant pitch combinations and consider the former more pleasant than the latter. The preference for consonance over dissonance was tested in a patient, I.R., who suffers from music perception and memory disorders as a result of bilateral lesions to the auditory cortex. In Experiment 1, I.R. was found to be unable to distinguish consonant from dissonant versions of musical excerpts taken from the classical repertoire by rating their pleasantness. I.R.'s indifference to dissonance was not due to a loss of all affective responses to music, however, since she rated the same excerpts as happy or sad, as normal controls do. In Experiment 2, I.R.'s lack of responsiveness to varying degrees of dissonance was replicated with chord sequences which had been used in a previous study using PET, in examining emotional responses to dissonance. A CT scan of I.R.'s brain was co-registered with the PET activation data from normal volunteers. Comparison of I.R.'s scan with the PET data revealed that the damaged areas overlapped with the regions identified to be involved in the perceptual analysis of the musical input, but not with the paralimbic regions involved in affective responses. Taken together, the findings suggest that dissonance may be computed bilaterally in the superior temporal gyri by specialized mechanisms prior to its emotional interpretation. (+info)Aetiology and clinical presentations of auditory processing disorders--a review. (2/30)
Auditory processing disorders may have detrimental consequences on a child's life, if undiagnosed and untreated. We review causes of auditory processing disorders in order to raise clinical awareness. Auditory processing disorders may present against a background of neurological disease or developmental disorders, as well as in isolation. Clinicians need to be aware of potential causes and implications of auditory processing disorders. (+info)Mutations in LGI1 cause autosomal-dominant partial epilepsy with auditory features. (3/30)
The epilepsies are a common, clinically heterogeneous group of disorders defined by recurrent unprovoked seizures. Here we describe identification of the causative gene in autosomal-dominant partial epilepsy with auditory features (ADPEAF, MIM 600512), a rare form of idiopathic lateral temporal lobe epilepsy characterized by partial seizures with auditory disturbances. We constructed a complete, 4.2-Mb physical map across the genetically implicated disease-gene region, identified 28 putative genes (Fig. 1) and resequenced all or part of 21 genes before identifying presumptive mutations in one copy of the leucine-rich, glioma-inactivated 1 gene (LGI1) in each of five families with ADPEAF. Previous studies have indicated that loss of both copies of LGI1 promotes glial tumor progression. We show that the expression pattern of mouse Lgi1 is predominantly neuronal and is consistent with the anatomic regions involved in temporal lobe epilepsy. Discovery of LGI1 as a cause of ADPEAF suggests new avenues for research on pathogenic mechanisms of idiopathic epilepsies. (+info)Deficits of musical timbre perception after unilateral temporal-lobe lesion revealed with multidimensional scaling. (4/30)
Thirty patients with unilateral temporal lobe excisions and 15 normal control subjects were tested in a task involving judgements of timbre dissimilarity in single tone and melodic conditions. Perceptual correlates of spectral and temporal parameters resulting from changing the number of harmonics and rise-time duration, respectively, were investigated by using a multidimensional scaling technique. The results of subjects with left temporal lobe lesion suggest that they were able to use the spectral and temporal envelopes of tones independently in making perceptual judgements of single tones. In the melodic condition, their results were significantly different from those of normal control subjects, suggesting that left temporal lesions do affect subtle aspects of timbre perception, despite these patients' preserved ability to make discrimination judgements using traditional paradigms. The major finding of this study concerns perceptual ratings obtained by subjects with right temporal lobe lesion, which revealed a disturbed perceptual space in both conditions. The most distorted results were obtained with single tones, in which the temporal parameter was less prominent. Tones were grouped according to their spectral content, but the results did not reflect a coherent underlying perceptual dimension. In general, the data from both patient groups (left lesions and right lesions) showed that the extraction of temporal cues was easier in the melodic than in the single tone condition, suggesting that the different durations and frequencies heard in a musical phrase enhance the importance of certain physical parameters. The findings of the present study replicate and extend previous results showing that timbre perception depends mainly upon the integrity of right neocortical structures, although a contribution of left temporal regions is also apparent. These data also demonstrate that multidimensional techniques are sensitive to more subtle perceptual disturbances that may not be revealed by discrimination paradigms. (+info)Congenital amusia: all the songs sound the same. (5/30)
Recent evidence from individuals born with a profound musical impairment suggests that the ability to process pitch information is normally present from birth. This finding supports the idea that the perception and appreciation of music, both of which critically depend on pitch processing, have a biological basis in the brain. (+info)Speech-sound-selective auditory impairment in children with autism: they can perceive but do not attend. (6/30)
In autism, severe abnormalities in social behavior coexist with aberrant attention and deficient language. In the attentional domain, attention to people and socially relevant stimuli is impaired the most. Because socially meaningful stimulus events are physically complex, a deficiency in sensory processing of complex stimuli has been suggested to contribute to aberrant attention and language in autism. This study used event-related brain potentials (ERP) to examine the sensory and early attentional processing of sounds of different complexity in high-functioning children with autism. Acoustically matched simple tones, complex tones, and vowels were presented in separate oddball sequences, in which a repetitive "standard" sound was occasionally replaced by an infrequent "deviant" sound differing from the standard in frequency (by 10%). In addition to sensory responses, deviant sounds elicited an ERP index of automatic sound-change discrimination, the mismatch negativity, and an ERP index of attentional orienting, the P3a. The sensory sound processing was intact in the high-functioning children with autism and was not affected by sound complexity or "speechness." In contrast, their involuntary orienting was affected by stimulus nature. It was normal to both simple- and complex-tone changes but was entirely abolished by vowel changes. These results demonstrate that, first, auditory orienting deficits in autism cannot be explained by sensory deficits and, second, that orienting deficit in autism might be speech-sound specific. (+info)Is there an association between noise exposure and King Kopetzky Syndrome? (7/30)
The condition in which individuals with normal pure tone audiograms complain of hearing difficulties, especially in the presence of background noise, (normal pure tone audiograms), has had a number of different names. The present term King-Kopetzky Syndrome was coined by Hinchcliffe in 1992. This is a common condition reported in 5 - 10% of those attending clinics complaining of hearing problems. A dominant genetic aetiology has been found in a proportion of cases. It may be associated with minor peripheral or central auditory dysfunction, and frequently the individuals exhibit anxious or depressive personalities. We found no relationship with noise exposure in a series of patients compared with matched controls. Here we review the evidence for and against such an influence and present fresh data in an attempt to define the role of noise, if any, in the causation of this condition. Our final conclusion is that there is no clear association between KKS and noise exposure (+info)Central auditory development: evidence from CAEP measurements in children fit with cochlear implants. (8/30)
In normal-hearing children the latency of the P1 component of the cortical evoked response to sound varies as a function of age and, thus, can be used as a biomarker for maturation of central auditory pathways. We assessed P1 latency in 245 congenitally deaf children fit with cochlear implants following various periods of auditory deprivation. If children experience less than 3.5 years of auditory deprivation before implantation, P1 latencies fall into the range of normal following 3-6 months of electrical stimulation. Children who experience greater than 7 years of deprivation, however, generally do not develop normal P1 latencies even after years of stimulation. Moreover, the waveforms for these patients can be markedly abnormal. Cortical reorganization stimulated by deprivation is likely to be a significant factor in both variation in the latency and morphology of the cortical evoked response to sound for children fit with a cochlear implant and variation in the development of oral speech and language function. LEARNING OUTCOMES: The reader will be introduced to research using cortical evoked responses (CAEPs), positron emission tomography (PET) scans and in-depth recording from the auditory cortex of congenitally deaf cats that converges on the existence of a sensitive period for the development of central auditory pathways in children. The reader will also be provided with two case studies that illustrate the use of the P1 response as biomarker for development of central auditory pathways. Finally, suggestions for future research will be provided. (+info)Central auditory diseases refer to a group of disorders that affect the processing of auditory information in the central nervous system, specifically in the brainstem and cortex. These disorders can result from various causes, such as head injuries, infections, tumors, or degenerative conditions. They can cause difficulties with understanding speech, locating the source of sounds, and perceiving complex or rapidly changing auditory stimuli.
Central auditory processing disorder (CAPD) is a common type of central auditory disease. It is a hearing problem that affects about 5% of school-aged children. Kids with CAPD can't process what they hear in the same way other kids do because their ears and brain don't fully coordinate. Something interferes with the way the brain recognizes and interprets sounds, especially speech.
CAPD is not a hearing loss or an intelligence problem. Children with CAPD have normal structural hearing and can often hear sounds that are presented to them individually. However, they may struggle to understand speech in noisy environments, follow complex directions, or distinguish similar sounds from one another.
Central auditory diseases are typically diagnosed through a series of tests that assess different aspects of auditory processing, such as speech recognition in noise, temporal processing, and binaural integration. Treatment for these disorders may include auditory training, assistive listening devices, and environmental modifications to help compensate for the processing difficulties.
Audiology is a branch of science that deals with the study of hearing, balance disorders, and related conditions. It involves the assessment, diagnosis, and treatment of hearing and balance problems using various tests, techniques, and devices. Audiologists are healthcare professionals who specialize in this field and provide services such as hearing evaluations, fitting of hearing aids, and counseling for people with hearing loss or tinnitus (ringing in the ears). They also work closely with other medical professionals to manage complex cases and provide rehabilitation services.
An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.
Prevalence, in medical terms, refers to the total number of people in a given population who have a particular disease or condition at a specific point in time, or over a specified period. It is typically expressed as a percentage or a ratio of the number of cases to the size of the population. Prevalence differs from incidence, which measures the number of new cases that develop during a certain period.
The inner ear is the innermost part of the ear that contains the sensory organs for hearing and balance. It consists of a complex system of fluid-filled tubes and sacs called the vestibular system, which is responsible for maintaining balance and spatial orientation, and the cochlea, a spiral-shaped organ that converts sound vibrations into electrical signals that are sent to the brain.
The inner ear is located deep within the temporal bone of the skull and is protected by a bony labyrinth. The vestibular system includes the semicircular canals, which detect rotational movements of the head, and the otolith organs (the saccule and utricle), which detect linear acceleration and gravity.
Damage to the inner ear can result in hearing loss, tinnitus (ringing in the ears), vertigo (a spinning sensation), and balance problems.
The auditory threshold is the minimum sound intensity or loudness level that a person can detect 50% of the time, for a given tone frequency. It is typically measured in decibels (dB) and represents the quietest sound that a person can hear. The auditory threshold can be affected by various factors such as age, exposure to noise, and certain medical conditions. Hearing tests, such as pure-tone audiometry, are used to measure an individual's auditory thresholds for different frequencies.
Acoustic stimulation refers to the use of sound waves or vibrations to elicit a response in an individual, typically for the purpose of assessing or treating hearing, balance, or neurological disorders. In a medical context, acoustic stimulation may involve presenting pure tones, speech sounds, or other types of auditory signals through headphones, speakers, or specialized devices such as bone conduction transducers.
The response to acoustic stimulation can be measured using various techniques, including electrophysiological tests like auditory brainstem responses (ABRs) or otoacoustic emissions (OAEs), behavioral observations, or functional imaging methods like fMRI. Acoustic stimulation is also used in therapeutic settings, such as auditory training programs for hearing impairment or vestibular rehabilitation for balance disorders.
It's important to note that acoustic stimulation should be administered under the guidance of a qualified healthcare professional to ensure safety and effectiveness.
In the context of medicine, particularly in the field of auscultation (the act of listening to the internal sounds of the body), "sound" refers to the noises produced by the functioning of the heart, lungs, and other organs. These sounds are typically categorized into two types:
1. **Bradyacoustic sounds**: These are low-pitched sounds that are heard when there is a turbulent flow of blood or when two body structures rub against each other. An example would be the heart sound known as "S1," which is produced by the closure of the mitral and tricuspid valves at the beginning of systole (contraction of the heart's ventricles).
2. **High-pitched sounds**: These are sharper, higher-frequency sounds that can provide valuable diagnostic information. An example would be lung sounds, which include breath sounds like those heard during inhalation and exhalation, as well as adventitious sounds like crackles, wheezes, and pleural friction rubs.
It's important to note that these medical "sounds" are not the same as the everyday definition of sound, which refers to the sensation produced by stimulation of the auditory system by vibrations.
Ependymoma is a type of brain or spinal cord tumor that develops from the ependymal cells that line the ventricles (fluid-filled spaces) in the brain, or the central canal of the spinal cord. These tumors can be benign or malignant, and they can cause various symptoms depending on their location and size.
Ependymomas are relatively rare, accounting for about 2-3% of all primary brain and central nervous system tumors. They most commonly occur in children and young adults, but they can also affect older individuals. Treatment typically involves surgical removal of the tumor, followed by radiation therapy or chemotherapy, depending on the grade and location of the tumor. The prognosis for ependymomas varies widely, with some patients experiencing long-term survival and others having more aggressive tumors that are difficult to treat.
I'm sorry for any confusion, but "Information Centers" is not a medical term per se. However, in a broad context, information centers can refer to organized locations that provide specific health-related or medical information to patients, healthcare professionals, or the general public. These can be found in hospitals, clinics, universities, government agencies, and other organizations. They offer access to various resources such as books, pamphlets, databases, and online tools, with the aim of promoting evidence-based practices, enhancing knowledge, and supporting decision-making.
The sacrococcygeal region is the lower part of the back where the spine ends, specifically referring to the area where the sacrum (a triangular bone at the base of the spine formed by the fusion of several vertebrae) meets the coccyx (also known as the tailbone). This region is located at the very bottom of the spine and is susceptible to injury or trauma due to its position and role in supporting the body's weight. It is also a common site for birth defects, particularly in newborns.
Spinal cord neoplasms refer to abnormal growths or tumors within the spinal cord. These can be benign (non-cancerous) or malignant (cancerous). They originate from the cells within the spinal cord itself (primary tumors), or they may spread to the spinal cord from other parts of the body (metastatic tumors). Spinal cord neoplasms can cause various symptoms depending on their location and size, including back pain, neurological deficits, and even paralysis. Treatment options include surgery, radiation therapy, and chemotherapy.
I'm sorry for any confusion, but "Internet" is a term that pertains to the global network of interconnected computers and servers that enable the transmission and reception of data via the internet protocol (IP). It is not a medical term and does not have a specific medical definition. If you have any questions related to medicine or health, I'd be happy to try to help answer them for you!
A rare disease, also known as an orphan disease, is a health condition that affects fewer than 200,000 people in the United States or fewer than 1 in 2,000 people in Europe. There are over 7,000 rare diseases identified, and many of them are severe, chronic, and often life-threatening. The causes of rare diseases can be genetic, infectious, environmental, or degenerative. Due to their rarity, research on rare diseases is often underfunded, and treatments may not be available or well-studied. Additionally, the diagnosis of rare diseases can be challenging due to a lack of awareness and understanding among healthcare professionals.
