Characterization of MK-801-induced behavior as a putative rat model of psychosis. (1/57)
The objective of this study was to characterize the behavior induced by the N-methyl-D-aspartate receptor antagonist MK-801 (dizocilpine maleate) in rats as a model of psychosis. The temporal profile, dose dependence, age, and sex differences of the behavior are described. A gas chromatographic method for the analysis of MK-801 in plasma and brain was developed. Female rats showed 4 to 10 times more MK-801-induced behavior and displayed around 25 times higher serum and brain concentrations of MK-801 than male rats. Twenty-one neuroactive compounds, including a number of excitatory amino acid-active substances, were tested for the effect on MK-801-induced behavior. Neuroleptics blocked MK-801-induced behavior in a dose-dependent manner that correlated to their antipsychotic potency in humans. Adenosine receptor agonists and an N-methyl-D-aspartate receptor-associated glycine site antagonist showed putative antipsychotic effects. In conclusion, MK-801-induced behavior represents a rat excitatory amino acid hypofunction model of psychosis that appears to be of clinical relevance and may be of value in the search for new antipsychotic agents. (+info)Further analysis of problem behavior in response class hierarchies. (2/57)
A functional analysis identified the reinforcers for 3 participants' problem behavior, but only relatively mild problem behaviors (e.g., screaming, disruption) were observed when all topographies produced tested consequences. We then conducted an extinction analysis in which specific topographies produced a reinforcer while all other topographies were on extinction. The extinction analysis confirmed that the same reinforcer identified in the initial functional analysis maintained more severe topographies of problem behavior (e.g., aggression). In addition, results of the extinction analysis indicated that 2 of the participants displayed patterns of responding consistent with a response class hierarchy hypothesis, in which less severe problem behavior frequently occurred prior to more severe topographies. The 3rd participant displayed a response pattern indicative of differential reinforcement effects. (+info)EphB2 guides axons at the midline and is necessary for normal vestibular function. (3/57)
Mice lacking the EphB2 receptor tyrosine kinase display a cell-autonomous, strain-specific circling behavior that is associated with vestibular phenotypes. In mutant embryos, the contralateral inner ear efferent growth cones exhibit inappropriate pathway selection at the midline, while in mutant adults, the endolymph-filled lumen of the semicircular canals is severely reduced. EphB2 is expressed in the endolymph-producing dark cells in the inner ear epithelium, and these cells show ultrastructural defects in the mutants. A molecular link to fluid regulation is provided by demonstrating that PDZ domain-containing proteins that bind the C termini of EphB2 and B-ephrins can also recognize the cytoplasmic tails of anion exchangers and aquaporins. This suggests EphB2 may regulate ionic homeostasis and endolymph fluid production through macromolecular associations with membrane channels that transport chloride, bicarbonate, and water. (+info)Reinforcing variability in adolescents with autism. (4/57)
Five adolescents with autism, 5 adult control participants, and 4 child controls received rewards for varying their sequences of responses while playing a computer game. In preceding and following phases, rewards were provided at approximately the same rate but were independent of variability. The most important finding was that, when reinforced, variability increased significantly in all groups. Reinforced variability could provide the necessary behavioral substrate for individuals with autism to learn new responses. (+info)Analyzing the multiple functions of stereotypical behavior for students with autism: implications for assessment and treatment. (5/57)
We studied behavioral functions associated with stereotypical responses for students with autism. In Study 1, analogue functional analyses (attention, demand, no-attention, and recreation conditions) were conducted for 5 students. Results suggested that stereotypy was multiply determined or occurred across all assessment conditions. For 2 students, stereotypy was associated with positive and negative reinforcement and the absence of environmental stimulation. For 2 other students, stereotypy occurred at high levels across all experimental conditions. For the 5th student, stereotypy was associated with negative reinforcement and the absence of environmental stimulation. In Study 2, the stereotypy of 1 student was further analyzed on a function-by-function basis. Within a concurrent-schedules procedure, alternative responses were taught to the student using functional communication training. The results of Study 2 showed that similar topographies of stereotypy, based on qualitatively different reinforcers, were reduced only when differential reinforcement contingencies for alternative forms of communication were implemented for specific response-reinforcer relations. Our results suggest that the causes of stereotypy for students with autism are complex and that the presumed association between response topography and behavioral function may be less important than previously realized. (+info)Adrenergic hyperactivity and metanephrine excess in the nucleus accumbens after prefrontocortical dopamine depletion. (6/57)
Selective dopamine depletion within the medial prefrontal cortex in rats is known to enhance dopamine and norepinephrine levels in the nucleus accumbens and to induce characteristic behavioral disturbances. The present study was designed to determine levels of adrenaline, apart from dopamine and norepinephrine, and metabolites in the nucleus accumbens after prefrontocortical dopamine depletion. Prefrontocortical dopamine depletion was carried out by injecting 6-hydroxydopamine, and it was validated through: the emergence of behavioral disturbances such as amphetamine-induced stereotypies, spontaneous motor hyperactivity, and enhanced "anxiety-like" responses and through postmortem quantification of catecholamine levels by using high-performance liquid chromatography. The findings indicated that lesioned rats exhibited more oral stereotypies after amphetamine, were hyperlocomotive, and showed more pronounced anxiety-like behaviors than controls. Following prefrontocortical dopamine depletion, postmortem concentrations of dopamine and norepinephrine, along with the metabolites 3,4-dihydroxyphenylacetic acid and vanillylmandelic acid, were reliably enhanced in the nucleus accumbens as expected, and dopamine turnover was decreased. Furthermore the nucleus accumbens contained higher levels of adrenaline and its transmethylated metabolite metanephrine. To sum up, prefrontocortical dopamine depletion induces motor and emotional disturbances in rats and alters the neurochemical profile of the nucleus accumbens, not only inducing dopaminergic and noradrenergic hyperactivity but also leading to adrenaline and metanephrine excess. (+info)Further evaluation of the role of protective equipment in the functional analysis of self-injurious behavior. (7/57)
Using a procedure similar to the one described by Le and Smith (in press), we evaluated the effects of protective equipment during a functional analysis for 2 individuals who engaged in severe self-injurious behavior (SIB). Results of our analyses revealed that the use of protective equipment during functional analyses of SIB suppressed levels of responding such that a behavioral function could not be identified. (+info)Conditions of application of repeated transcranial magnetic stimulation to rats may mask the effects of the treatment. (8/57)
Rats of sham repeated transcranial magnetic stimulation (rTMS) group, kept in noisy room and transiently immobilized (5 min) for 12 consecutive days, showed similar inhibition of body weight gain, increase in exploratory locomotor activity, and elevation of motor response to apomorphine as rats undergoing magnetic stimulation of the brain, and had only slightly lower response in apomorphine stereotypy. Some of the responses ascribed to antidepressant action of rTMS in animal experiment may be due to environmental conditions, and not alternating magnetic field passing the brain. (+info)Stereotypic Movement Disorder is a neurological condition characterized by the presence of repetitive, often rhythmic and seemingly driven movements that are apparently purposeless. These movements may include body rocking, head banging, hand wringing, or complex whole-body movements. The movements interfere with normal activities and development, and they are not better explained by a neurological condition or another mental disorder. Stereotypic Movement Disorder can occur in individuals of all ages, but it is most commonly diagnosed in children and adolescents. The exact cause of the disorder is unknown, but it may be associated with genetic factors, brain abnormalities, or environmental influences.
Movement disorders are a group of neurological conditions that affect the control and coordination of voluntary movements. These disorders can result from damage to or dysfunction of the cerebellum, basal ganglia, or other parts of the brain that regulate movement. Symptoms may include tremors, rigidity, bradykinesia (slowness of movement), akathisia (restlessness and inability to remain still), dystonia (sustained muscle contractions leading to abnormal postures), chorea (rapid, unpredictable movements), tics, and gait disturbances. Examples of movement disorders include Parkinson's disease, Huntington's disease, Tourette syndrome, and dystonic disorders.
In the context of medicine and healthcare, "movement" refers to the act or process of changing physical location or position. It involves the contraction and relaxation of muscles, which allows for the joints to move and the body to be in motion. Movement can also refer to the ability of a patient to move a specific body part or limb, which is assessed during physical examinations. Additionally, "movement" can describe the progression or spread of a disease within the body.
Dystonia is a neurological movement disorder characterized by involuntary muscle contractions, leading to repetitive or twisting movements. These movements can be painful and may affect one part of the body (focal dystonia) or multiple parts (generalized dystonia). The exact cause of dystonia varies, with some cases being inherited and others resulting from damage to the brain. Treatment options include medications, botulinum toxin injections, and deep brain stimulation surgery.
Chorea is a medical term that describes an involuntary movement disorder characterized by brief, irregular, and abrupt jerky movements. These movements often occur randomly and can affect any part of the body. Chorea can also cause difficulty with coordination and balance, and can sometimes be accompanied by muscle weakness or rigidity.
The term "chorea" comes from the Greek word "χορεία" (khoréia), which means "dance," reflecting the graceful, dance-like movements that are characteristic of this condition. Chorea can occur as a symptom of various underlying medical conditions, including neurological disorders such as Huntington's disease, Sydenham's chorea, and cerebral palsy, as well as metabolic disorders, infections, and certain medications.
Treatment for chorea depends on the underlying cause of the condition and may include medications to help control the involuntary movements, physical therapy to improve coordination and balance, and lifestyle modifications to reduce the risk of injury from falls or other accidents. In some cases, surgery may be recommended as a last resort for severe or refractory chorea.
Dystonic disorders are a group of neurological conditions characterized by sustained or intermittent muscle contractions that result in involuntary, repetitive, and often twisting movements and abnormal postures. These movements can affect any part of the body, including the face, neck, limbs, and trunk. Dystonic disorders can be primary, meaning they are caused by genetic mutations or idiopathic causes, or secondary, resulting from brain injury, infection, or other underlying medical conditions.
The most common form of dystonia is cervical dystonia (spasmodic torticollis), which affects the muscles of the neck and results in abnormal head positioning. Other forms of dystonia include blepharospasm (involuntary eyelid spasms), oromandibular dystonia (affecting the muscles of the jaw, face, and tongue), and generalized dystonia (affecting multiple parts of the body).
Dystonic disorders can significantly impact a person's quality of life, causing pain, discomfort, and social isolation. Treatment options include oral medications, botulinum toxin injections, and deep brain stimulation surgery in severe cases.
Parkinson's disease is a progressive neurodegenerative disorder that affects movement. It is characterized by the death of dopamine-producing cells in the brain, specifically in an area called the substantia nigra. The loss of these cells leads to a decrease in dopamine levels, which results in the motor symptoms associated with Parkinson's disease. These symptoms can include tremors at rest, stiffness or rigidity of the limbs and trunk, bradykinesia (slowness of movement), and postural instability (impaired balance and coordination). In addition to these motor symptoms, non-motor symptoms such as cognitive impairment, depression, anxiety, and sleep disturbances are also common in people with Parkinson's disease. The exact cause of Parkinson's disease is unknown, but it is thought to be a combination of genetic and environmental factors. There is currently no cure for Parkinson's disease, but medications and therapies can help manage the symptoms and improve quality of life.
Essential tremor is a type of involuntary tremor, or shaking, that primarily affects the hands and arms. It can also affect the head, vocal cords, and other parts of the body. Essential tremor is often confused with Parkinson's disease, as they share some similar symptoms, but essential tremor is generally not associated with other neurological conditions.
The tremors associated with essential tremor typically occur when a person is performing voluntary movements, such as writing, eating, or using tools. The shaking may also occur at rest, but this is less common. Essential tremor usually worsens with stress, fatigue, and age.
While the exact cause of essential tremor is not known, it appears to have a genetic component, as it tends to run in families. In some cases, essential tremor may be related to alcohol use or other factors. There is no cure for essential tremor, but medications and lifestyle changes can help manage the symptoms and improve quality of life.
'Dystonia Musculorum Deformans' is a medical term that refers to a rare inherited neurological disorder, which is now more commonly known as "Generalized Dystonia." This condition is characterized by sustained muscle contractions, leading to twisting and repetitive movements or abnormal postures.
The onset of symptoms typically occurs during childhood or adolescence, and they can progress over time, affecting various parts of the body. The exact cause of Generalized Dystonia is not fully understood, but it is believed to involve genetic mutations that affect the functioning of certain proteins in the brain. Treatment options may include medications, botulinum toxin injections, or even deep brain stimulation surgery in severe cases.
Parkinsonian disorders are a group of neurological conditions characterized by motor symptoms such as bradykinesia (slowness of movement), rigidity, resting tremor, and postural instability. These symptoms are caused by the degeneration of dopamine-producing neurons in the brain, particularly in the substantia nigra pars compacta.
The most common Parkinsonian disorder is Parkinson's disease (PD), which is a progressive neurodegenerative disorder. However, there are also several other secondary Parkinsonian disorders, including:
1. Drug-induced parkinsonism: This is caused by the use of certain medications, such as antipsychotics and metoclopramide.
2. Vascular parkinsonism: This is caused by small vessel disease in the brain, which can lead to similar symptoms as PD.
3. Dementia with Lewy bodies (DLB): This is a type of dementia that shares some features with PD, such as the presence of alpha-synuclein protein clumps called Lewy bodies.
4. Progressive supranuclear palsy (PSP): This is a rare brain disorder that affects movement, gait, and eye movements.
5. Multiple system atrophy (MSA): This is a progressive neurodegenerative disorder that affects multiple systems in the body, including the autonomic nervous system, motor system, and cerebellum.
6. Corticobasal degeneration (CBD): This is a rare neurological disorder that affects both movement and cognition.
It's important to note that while these disorders share some symptoms with PD, they have different underlying causes and may require different treatments.
