Abstract

Atropine (Atr) or mecamylamine (MeC) were administered locally into the periaqueductal gray (PAG) of rabbits with chronically implanted electrodes into the motor-sensory cortex (MSC) ventro-posterolateral thalamic nuclei (NVPL), PAG and midbrain reticular formation (MRF). Bioelectrical responses in the cortex and subcortical structures were analyzed automatically by means of Fast Fourier Transform and Autoregressive Method. Both Atr and Mec modified the activity in PAG, Atr had also the influence in MRF and MSC.

输尿管周围灰质局部给予阿托品和甲胺对家兔特定脑结构生物电活动的影响。
将电极长期植入运动感觉皮层(MSC)、丘脑腹后外侧核(NVPL)、PAG和中脑网状结构(MRF),将阿托品(Atr)或甲胺(MeC)局部注入兔导水管周围灰质(PAG)。采用快速傅立叶变换和自回归方法对皮层和皮层下结构的生物电响应进行了自动分析。Atr和Mec均能改变PAG的活性,Atr对MRF和MSC也有影响。
