Dysfunction of inhibitory–excitatory cortical circuits induces density-dependent facilitation of motor-evoked potentials after subarachnoid hemorrhage
= 0.0732). A high MEP amplitude just before surgery correlates well with Sylvian fissure HU values on initial CT and may reflect dysfunction in the cortical electrophysiological intracortical inhibitory-facilitatory neuronal circuits of SAH.
