Similar to the occipital alpha rhythm, electroencephalographic (EEG) signals in the alpha- and beta-frequency bands can be suppressed by movement or motor imagery and have thus been thought to represent the "idling state" of the sensorimotor cortex. A negative correlation between spontaneous alpha EEG and blood-oxygen-level-dependent (BOLD) signals has been reported in combined EEG and fMRI (fu...

for most people iterance to hospital is a disturbing experience and expects that nurses be sensitive to patient's physical, emotional and social need at admission. whereas interrupt of sleep due to physical, psychological and social status damage, knowing about effective mechanisms in retention and disturbance of sleep – wake cycles help nurses to make natural criteria for their patient&ap...

conclusions it seems that the incidence of different types of stroke-induced aphasia in ahvaz is influenced by the calendar-temporal changes. according to the findings, to prevent the occurrence of stroke-induced aphasia, necessary counseling should be provided for lifestyle changes. results according to the obtained results 39.9% of the studied patients had a stroke-induced aphasia. the highes...

Tai Chi (TC) is a slow-motion contemplative exercise that is associated with improvements in sensorimotor measures, including decreased force variability, enhanced tactile acuity, and improved proprioception, especially in elderly populations. Here, we carried out two studies evaluating the effect of TC practice on measures associated with sensorimotor processing. In study 1, we evaluated TC's ...

UNLABELLED Environmental rhythms potently drive predictive resource allocation in time, typically leading to perceptual and motor benefits for on-beat, relative to off-beat, times, even if the rhythmic stream is not intentionally used. In two human EEG experiments, we investigated the behavioral and electrophysiological expressions of using rhythms to direct resources away from on-beat times. T...

We investigated the distribution and diurnal variation of TR(beta)1 protein expression in liver with specific antibodies against TR(beta)1. Immunohistochemistry showed a zonal distribution of TR(beta)1 with maximum expression in the pericentral zone matching some known T(3)-responsive enzyme activities in the liver, such as glutamine synthetase, cholesterol 7alpha- hydroxylase, and spot 14. Com...

Background : given the similarity of clinical manifestations depressive disorder and episodes within framework bipolar affective disorder, diagnostic errors are inevitable. Both overdiagnosis underdiagnosis too common, it may take several years to establish a correct diagnosis. Despite fact that is impossible completely eliminate errors, important reduce their likelihood by better understanding...

Although beta oscillations (≈ 13-35 Hz) are often considered as a sensorimotor rhythm, their functional role remains debated. In particular, the modulations of beta power during preparation and execution of complex movements in different contexts were barely investigated. Here, we analysed the beta oscillations recorded with electroencephalography (EEG) in a precued grasping task in which we ma...

In healthy humans, the cortical brain rhythm shows specific mu (~6-14 Hz) and beta (~18-24 Hz) band patterns in the cases of both real and imaginary motor movements. As cerebellar ataxia is associated with impairment of precise motor movement control as well as motor imagery, ataxia is an ideal model system in which to study the role of the cerebellocortical circuit in rhythm control. We hypoth...
