Influence of short-interval intracortical inhibition on short-interval intracortical facilitation in human primary motor cortex.
Using the paired-pulse paradigm, transcranial magnetic stimulation (TMS) has revealed much about the human primary motor cortex (M1). A preceding subthreshold conditioning stimulus (CS) inhibits the excitability of the motor cortex, which is named short-interval intracortical inhibition (SICI). In contrast, facilitation is observed when the first pulse (S1) is followed by a second one at thresh...

20 Paired associative stimulation (PAS) of the motor cortex leads to increased motor evoked potential 21 (MEP) amplitudes in the stimulated hand muscles. We hypothesized that evoking GABA A receptor-22 mediated short-interval intracortical inhibition (SICI) simultaneously with excitatory PAS would depress 23 long-term potentiation plasticity in motor cortex. Four different PAS paradigms were te...

متن کاملDissecting the Mechanisms Underlying Short-Interval Intracortical Inhibition Using Exercise
Recently, 2 physiologically distinct phases of short-interval intracortical inhibition (SICI) have been identified, a larger phase at interstimulus interval (ISI) 3 ms and a smaller phase at ISI 1 ms. While the former is mediated by synaptic processes, the mechanisms underlying the first phase of SICI remain a matter of debate. Separately, it is known that fatiguing hand exercise reduces SICI, ...
