Neural representations of self-perception of voice: An intracortical evoked potential analysis based on an adolescent with right temporal lobe epilepsy.

• Own voice perception might be a complex process including emotional, memory, somatosensory, auditory, and facial recognition processing. • Right superior temporal gyrus, transverse temporal gyrus, amygdala, hippocampus, and fusiform gyrus (FG) are likely part of the neural network subjacent to own human voice perception. • Cortico-cortical evoked potentials might help to understand neurophysiological bases of own voice perception. • Own voice perception seem to be related to facial perception as well. The neural bases for language perception have been studied elsewhere using Transcranial Magnetic Stimulation, functional Magnetic Resonance Imaging and Direct Cortical Stimulation. However, to our knowledge, there is no previous report about a patient identifying the change in his voice tone, speed, and prosody because of right temporal cortical stimulation. Nor has there been a cortico-cortical evoked potential (CCEP) assessment of the network underlying this process. We present CCEP from a patient with right focal refractory temporal lobe epilepsy of tumoral etiology who reported changes in the perception of his own speech prosody during stimulation. This report will serve as a complement to the understanding of the neural networks of language and prosody. The present report shows that right superior temporal gyrus, transverse temporal gyrus, right amygdala, hippocampus, and fusiform gyrus (FG) are part of the neural network subjacent to own human voice perception.
