A new Clinical Neurophysiology study shows that cortical microstructure — specifically myelin content — shapes the earliest components of direct electrical stimulation responses, with implications for intra-operative brain mapping and why the g.HIamp amplifier’s artifact control matters.

Cortico-cortical evoked potentials (CCEPs) are a neurophysiological technique used to assess functional connectivity between different regions of the brain. By delivering electrical stimulation to one cortical area and recording the resulting activity in another, CCEPs help map brain networks involved in movement, sensation, and cognition.
