Analysis of the Cortico-Hippocampal activity related to Auditory Discrimination

Abstract

We carried out millisecond-scale multi-dipole estimations in the human brain related to auditory discrimination by using a 64-channel whole-cortex SQUID system. As a result, multiple activities were estimated in the cortico-limbic areas. The posterior hippocampal activity was most stable and prominent as compared with the others. These results show that the posterior hippocampal region is a central structure of a distributed cortico-hippocampal neural network during auditory discrimination processes in the human brain.
