Pleasant and unpleasant emotional stimuli are frequently conceptualized as motivators for action. This notion was examined using focal transcranial magnetic stimulation (TMS). Ten healthy participants viewed pleasant, neutral, and unpleasant pictures from the International Affective Picture System (IAPS). During picture viewing, focal TMS was applied to the right motor cortex over the area inne...
Hemispatial neglect is common after unilateral brain damage, particularly to perisylvian structures in the right-hemisphere (RH). In this disabling syndrome, behaviour and awareness are biased away from the contralesional side of space towards the ipsilesional side. Theoretical accounts of this in terms of hemispheric rivalry have speculated that the intact left-hemisphere (LH) may become hyper...
We used transcranial magnetic stimulation (TMS) to investigate whether an acute bout of resistance exercise with blood flow restriction (BFR) stimulated changes in corticomotor excitability (motor evoked potential, MEP) and short-interval intracortical inhibition (SICI), and compared the responses to two traditional resistance exercise methods. Ten males completed four unilateral elbow flexion ...
Temporary deafferentation of the upper limb, with ischemic or anesthetic nerve block, has rapid effects on sensorimotor cortex. Cutaneous anesthesia of the forearm has recently been found to improve sensory and motor function of the paretic hand in chronic stroke patients. However, the neurophysiological mechanisms are unknown. The aim of this study was to investigate the behavioral and neuroph...
BACKGROUND Transcranial magnetic stimulation (TMS) is a non-invasive means by which to assess the structure and function of the central nervous system. Current practices involve the administration of multiple stimuli over target areas of a participant's scalp. Decreasing the number of stimuli delivered during TMS assessments would improve time efficiency and decrease participant demand. However...
