| Abstract(in English) | Many studies of mismatch negativity (MMN) have been performed to investigate functional discrimination of sound in the brain. MMN is induced oddball sequence consisting of infrequent (deviant) sound stimuli and frequent (standard) sound stimuli. The MMN is considered to reflect sensory memory to standard stimuli and pre-attentive comparison between standard and deviant stimuli. It occurs, whereby, in the absence of attention and even under anesthesia. However, the neural mechanisms of the MMN are remained unclear. In this study, we measured temporal electroencephalogram (EEG) and hippocampal local field potential (LFP) simultaneously in anesthetized guinea pigs to the oddball sequence of sound duration. Consequently, MMN was not appeared in temporal EEG but hippocampal LFP exhibited MMN-like negative potential. |
