Abstract

Electrographic study was carried out in Wistar rats and the rats of genetical catalepsy (GC) strain. In contrast to Wistar rats epileptiform activity was observed in ECoG of GC rats being enhanced at the transition to a cataleptic state. Analysis of spectra and coherence of EEG revealed the presence of interhemispheric brain asymmetry in all the rats. In some frequency bands in GC rats inversion of interhemispheric asymmetry was found, which had been characteristic for Wistar strain. The highest interhemispheric synchronization of biopotentials was observed in the frontal cortical areas in GC rats and in the occipital areas in those of Wistar strain.

摘要

对Wistar大鼠和遗传性僵住症（GC）品系大鼠进行了脑电图研究。与Wistar大鼠不同，在GC大鼠的脑电图中观察到癫痫样活动，在转变为僵住状态时增强。脑电图的频谱和相干性分析表明，所有大鼠均存在大脑半球间不对称。在GC大鼠的某些频段中，发现了大脑半球间不对称的反转，这是Wistar品系的特征。在GC大鼠的额叶皮质区域观察到生物电位的最高半球间同步性，而在Wistar品系大鼠中则在枕叶区域观察到。
