Efficacy and Interindividual Variability in Motor-Cortex Plasticity following Anodal tDCS and Paired-Associative Stimulation
Interindividual response variability to various motor-cortex stimulation protocols has been recently reported. Comparative data of stimulation protocols with different modes of action is lacking. We aimed to compare the efficacy and response variability of two LTP-inducing stimulation protocols in the human motor cortex: anodal transcranial direct current stimulation (a-tDCS) and paired-associa...
متن کاملCerebellum to motor cortex paired associative stimulation induces bidirectional STDP-like plasticity in human motor cortex
The cerebellum is crucially important for motor control and adaptation. Recent non-invasive brain stimulation studies have indicated the possibility to alter the excitability of the cerebellum and its projections to the contralateral motor cortex, with behavioral consequences on motor control and adaptation. Here we sought to induce bidirectional spike-timing dependent plasticity (STDP)-like mo...
متن کاملFunctional Recovery in a Primate Model of Parkinson's Disease following Motor Cortex Stimulation
A concept in Parkinson's disease postulates that motor cortex may pattern abnormal rhythmic activities in the basal ganglia, underlying the genesis of observed motor symptoms. We conducted a preclinical study of electrical interference in the primary motor cortex using a chronic MPTP primate model in which dopamine depletion was progressive and regularly documented using 18F-DOPA positron tomog...
متن کاملPlastic change of motor cortex induced by transcutaneous electric nerve stimulation
Synopsis To investigate if motor cortical representation shows plastic change after short-term somatosensory stimulation, the brain activation during the right thumb movement was compared before and after transcutaneous electric nerve stimulation (TENS) by using fMRI. The activation in the primary motor area (M1) decreased after the intervention with TENS. This reduction lasted for 30 min. The ...
متن کاملPriming Pharyngeal Motor Cortex by Repeated Paired Associative Stimulation
BACKGROUND Several stimulation parameters can influence the neurophysiological and behavioral effects of paired associative stimulation (PAS), a neurostimulation paradigm that repeatedly pairs a peripheral electrical with a central cortical (transcranial magnetic stimulation [TMS]) stimulus. This also appears to be the case when PAS is applied to the pharyngeal motor cortex (MI), with some vari...
