| Research Abstract |
The current study investigated the visually evoked oscillations for subject's family name using magnetoencephalography (MEG). Twenty SZ patients and 20 normal controls (NC) participated in this study. The MEG signals were acquired using a whole-head, 306-channel sensor array. In this study, we presented visually four types of Japanese character string (kana): (1) subject's family name (30%), (2) another family name (30%), (3) meaningless string (30%), (4) a Japanese city name (target, 10%). In the mean power of evoked high gamma oscillations between 190msec and 210msec after stimulus onset, a repeated measures ANOVA demonstrated significant stimulus-by-group interactions. In post-hoc analyses, NC showed a significant difference (subject's family name>another family name>meaning less string), but there was no significant stimulus effect in SZ. The high gamma frequency neural oscillatory abnormalities of SZ may indicate a new evidence for neural basis of derangement of ego.
