background and objective: parkinson's disease (pd) is an age-related neurodegenerative disease with selective damage of dopaminergic neurons of the mesencephalon. l-dihydroxyphenylamine (l-dopa) therapy is currently the gold standard maneuver for pd. due to the protective, anti-inflammatory, and antioxidant effect of sesamin, this study was undertaken to assess dose-dependent effect of thi...

Handedness is the clearest example of behavioral lateralization in humans. It is not known whether the obvious asymmetry manifested by hand preference is associated with similar asymmetry in brain activation during movement. We examined the functional activation in cortical motor areas during movement of the dominant and nondominant hand in groups of right-handed and left-handed subjects and fo...

AIM The aim of this study was to assess the results of unilateral subthalamic nucleus (STN) stimulation for the treatment of Parkinson"s disease (PD) with marked asymmetry of parkinsonian motor symptoms and early motor complications. MATERIAL AND METHODS The clinical series consisted of 32 consecutive PD patients, in whom unilateral STN stimulation was performed. All patients were assessed ac...

The aim of the study was to investigate fine motor performance and ascertain age-related changes in laterality between the dominant and non-dominant hand. A representative sample of 635 adults (144 males and 491 females) aged 50 years and over completed a test battery MLS (Motor Performance Series) to assess a broad range of hand functions. Functional asymmetry was observed in all four motor te...

OBJECTIVE To evaluate the impact of forced use therapy on posture in children with hemiplegic cerebral palsy. DESIGN Single group pre- and post-training assessments. SUBJECTS Eight children (mean age 10.5 years (standard deviation 1.26 years)) with hemiplegic cerebral palsy Levels I and II on the gross motor function classification scale. METHODS All participants underwent 12 days (6 h/da...

Like humans, chimpanzees display robust and consistent hand preferences during the performance of certain tasks. Although correlations have been demonstrated between gross anatomic measures of primary motor cortex asymmetry and handedness in captive chimpanzees, the relationship between histological architecture and behavioral lateralization has not yet been investigated. Therefore, we examined...

Motor neglect, underuse of one side of the body not explained by weakness or sensory impairment, is a common consequence of stroke that is surprisingly little understood. Behavioural and neuroanatomical hallmarks of the disorder are investigated. Using a masked prime task, it was shown that when patients with left motor neglect plan to move their left hand, irrelevant right limb motor programme...

Absract: We have evaluated central motor pathways involvement and central inhibition in patients with brain gliomas. TMS (single-pulse protocol) was used; MEP amplitudes, latency, central motor conduction time (CMCT), CMCT asymmetry and silent period were evaluated. 12 glioma patients and 16 controls were enrolled.

The paper proposes the current performance enhancing method for dual three-phase permanent magnet synchronous motor (DTP-PMSM) with identical back-electromotive force (EMF) two winding sets accounting common-mode (CM) suppression. Considering inevitable asymmetry of parameters in motor, pulse cancellation theory is proposed which releases duty cycle freedom conventional zero CM voltage (ZCMV) w...

This paper aims to examine the nature of width, depth and configuration distribution along Kuya River and their temporal directionality of changes. It also pays attention to prepare some simplified indices regarding basin asymmetry, channel asymmetry and river bank stability and to explain the nature of basin and channel asymmetry and river bank stability using those constructed indices. Irregu...
