Abstract

EEG-correlates of completed functional brain reorganization following its lesion were studied on six adult cats. Performance by the cats of a conditioned delayed food reflex restored after a bilateral ablation of the temporal cortical areas, was attended with the statistically significant changes in both temporal and spatial patterns of probability of appearance of single EEG-oscillations for all the studied frequency ranges: 2.0-4.5; 4.5-7.5; 7.5-10.5; 10.5-14.0 c/s. Reorganization of brain activity was characterized by a vast involvement of all the studied brain structures and areas: the frontal, parietal, occipital cortex, the ventral and dorsal hippocampus, the caudate nucleus head, the thalamic mediodorsal nucleus and hypothalamic lateral area.

摘要

在六只成年猫身上研究了脑损伤后完成功能性脑重组的脑电图相关性。在双侧切除颞叶皮质区域后,猫的条件性延迟食物反射表现得以恢复,同时在所有研究频率范围(2.0 - 4.5;4.5 - 7.5;7.5 - 10.5;10.5 - 14.0赫兹)内,单个脑电图振荡出现概率的时间和空间模式都发生了统计学上的显著变化。脑活动重组的特征是所有研究的脑结构和区域广泛参与:额叶、顶叶、枕叶皮质、腹侧和背侧海马体、尾状核头部、丘脑背内侧核和下丘脑外侧区。
