Abstract

By means of daily alimentary deprivation the dominant of hunger was created in rabbits. In response to acoustic stimuli summational swallowing and chewing movements appeared. Spectral analysis of the electrical brain activity showed the presence of primary dominant focus zone (lateral and ventromedial hypothalamus), characterized by an increase of spectrum power in delta-range while in the orbito-frontal, sensorimotor, parietal cerebral cortex, in the medial and lateral preoptic hypothalamic zones the power of biopotentials spectrum decreased within the whole analyzed frequency range.

摘要

通过每日食物剥夺在兔子身上制造饥饿主导状态。对声音刺激的反应出现了吞咽和咀嚼动作的总和。脑电图的频谱分析显示存在初级主导焦点区（下丘脑外侧和腹内侧），其特征是δ波段频谱功率增加，而在眶额、感觉运动、顶叶大脑皮层以及下丘脑内侧和外侧视前区，生物电位频谱功率在整个分析频率范围内下降。
