Electrophysiological and behavioral studies in primary dystonia suggest abnormalities during movement preparation, but this crucial phase preceding movement onset has not yet been studied specifically with functional magnetic resonance imaging (fMRI). To identify abnormalities in brain activation during movement preparation, we used event-related fMRI to analyze behaviorally unimpaired sequenti...
background: spinal muscular atrophy (sma) is the second most common lethal autosomal recessive disease. it is a neuromuscular disorder caused by degenerative of lower motor neurons and occasionally bulbar neurons leading to progressive limb paralysis and muscular atrophy. the smn1 gene is recognized as a sma causing gene while naip has been characterized as a modifying factor for the clinical s...
When attempting to memorize action sentences (e.g., open an umbrella), performing the action of the sentence (enacted encoding) results in better memory performance than simply memorizing the sentences (verbal encoding). This memory enhancement is called the enactment effect. Magnetoencephalography (MEG) was used to elucidate whether the enactment effect is due to physical motor information or ...
Voluntary actions typically produce suppression of afferent sensation from the moving body part. We used transcranial magnetic stimulation to delay the output of motor commands from the motor cortex during voluntary movement. We show attenuation of sensation during this delay, in the absence of movement. We conclude that sensory suppression mainly relies on central signals related to the prepar...
Huntington disease (HD) is caused by an expanded HTT CAG repeat that leads in a length-dependent, completely dominant manner to onset of a characteristic movement disorder. HD also displays early mortality, so we tested whether the expanded CAG repeat exerts a dominant influence on age at death and on the duration of clinical disease. We found that, as with clinical onset, HD age at death is de...
Practicing a motor task can induce neuroplastic changes in the human primary motor cortex (M1) that are subsequently consolidated, leading to a stable memory trace. Currently, little is known whether early consolidation, tested several minutes after skill acquisition, can be improved by behavioral interventions. Here we test whether movement observation, known to evoke similar neural responses ...
Deep brain stimulation (DBS) of the thalamus (Vo/Vim) has become popular as a means of controlling involuntary movements, including post-stroke movement disorders. We have also found that post-stroke movement disorders and motor weakness can sometimes be controlled by motor cortex stimulation (MCS). In some forms of movement disorders, motor dysfunction becomes evident only when patients intend...
Introduction: VARK learning styles are included visual, listening, reading and writing and performance styles or movement (learning by touching, hearing, smelling, tasting and seeing) styles. The aim of this study was to determine students' learning styles preference and their relationships in Medical Sciences students. Materials and Methods: This was a Cross-sectional study in which 80 ...
The Effect of Motor Dependent/Independent Visual Perception Training on Visual-Motor Integration and Fine Skills 7-8-year-old Children: Retest Movement Hypothesis
During the past decade, electrophysiological approaches have greatly improved understanding of the involvement of the basal ganglia in motor behaviour. This review reports that the basal ganglia contribute to the initiation of movement by arousing executive motor centres via a disinhibitory mechanism. We propose that the basal ganglia output is used as a movement template specifying the motor e...
