Ipsilateral Motor Evoked Potentials and Intracortical Inhibition

Seeking to better understand the role of ipsilateral primary motor cortex during functional motor tasks, Byblow and colleagues examined whether ipsilateral motor evoked potentials (iMEPs) in the biceps brachii would be suppressed by sub-threshold conditioning, thereby demonstrating short-interval intracortical inhibition of iMEPs. In this podcast, Editor-in-Chief Bill Yates (University of Pittsburgh) and Associate Editor Monica A. Perez (University of Miami) join authors Winston Byblow (University of Auckland) and Alana McCambridge (University of Auckland) in an engaging discussion about their recent work. Are ipsilateral motor evoked potentials subject to intracortical inhibition? Listen and find out.
