Abstract:
We examined auditory evoked potentials and passive event-related potentials in two patients with hydranencephaly. In the middle latency response, a Na component was observed in both cases. Mismatch negativity was elicited in response to tone bursts and three patterns of vowel sounds in Patient 1, and three patterns of vowel stimuli in Patient 2. These results implicate the subcortical components of the auditory system in the generation of mismatch negativity.
