Somatosensory Evoked Potentials (SSEP) - NeurophysPedia
Oct 3, 2024 · Somatosensory Evoked Potentials (SSEPs) are electric signals recorded from the scalp or spine following stimulation to the peripheral nerves. They are time-locked responses, …
As detailed below, a minimum of four channels are required to record SSEPs. Use of averagers with less than four channels is discouraged. In this text, Cc and Ci correspond to C3 or C4 …
