MEDIAN NERVE STIMULATION PO TENTIATES THE MU SCLE RESPONSES TO TRANS C RANIAL MAGNETIC STIMULATION
Motor responses evoked by transcranial magnetic stimulation OMS) or transcranial electrical stimulation (TCS) can be facilitated by a prior conditioning stimulus to an afferent nerve. Two facilitation periods are described short (SI), when the nerve stimulus is given near 0 to 10 ms after cranial stimulation, and long (LI), when nerve stimulation is given 25-60 ms before the cranial stimula...
متن کاملCortical inhibition in attention deficit hyperactivity disorder: new insights from the electroencephalographic response to transcranial magnetic stimulation.
Attention deficit hyperactivity disorder is one of the most frequent neuropsychiatric disorders in childhood. Transcranial magnetic stimulation studies based on muscle responses (motor-evoked potentials) suggested that reduced motor inhibition contributes to hyperactivity, a core symptom of the disease. Here we employed the N100 component of the electroencephalographic response to transcranial ...
متن کاملDoes the Longer Application of Anodal-Transcranial Direct Current Stimulation Increase Corticomotor Excitability Further? A Pilot Study
Introduction: Anodal transcranial direct current stimulation (a-tDCS) of the primary motor cortex (M1) has been shown to be effective in increasing corticomotor excitability. Methods: We investigated whether longer applications of a-tDCS coincide with greater increases in corticomotor excitability compared to shorter application of a-tDCS. Ten right-handed healthy participants received one se...

متن کاملEffects of High-Frequency Repetitive Transcranial Magnetic Stimulation on Motor Functions in Patients with Subcortical Stroke
Background: Motor function impairment occurs in approximately two-thirds of patients with subcortical stroke. Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive technique for modulating cortical excitability. Objectives: The present study was designed for assessing the efficacy of high-frequency rTMS (5 Hz) on ipsilesional primary motor cortex in patients with subcortical stro...
