Abstract

The paper deals with spreading of the positive wave (P-wave), appearing in response to stimulation of the basal preoptic area (BPA) in the structures of meso-diencephalic and bulbar levels, predominantly involved into synchronizing and desynchronizing brain systems. It is shown that P-wave is mostly pronounced in the structures situated along the medial fascicle of the forebrain, its bilateral coagulation leading to changes in wave characteristics in the studied structures. Besides, after section of the medial fascicle of the forebrain pronounced inhibitory effects of the posterior hypothalamus on P-wave appearing in response to stimulation of BPA, are considerably weakened.

摘要

本文探讨了正波（P波）的传播，该正波是在中脑-间脑和延髓水平结构中对基底视前区（BPA）进行刺激时出现的，主要参与大脑系统的同步化和去同步化。结果表明，P波在前脑内侧束沿线的结构中最为明显，对其进行双侧凝固会导致所研究结构中波的特征发生变化。此外，切断前脑内侧束后，下丘脑后部对因刺激BPA而出现的P波的明显抑制作用会显著减弱。
