To study the role of cholinergic transmitter system in the maintenance of sychronizing limbic influences, the dynamics of the spatial distribution of the changes of cross-correlation coefficients of rabbits EEG led by 24 electrodes, was estimated at application of acetylcholine solution to the visual cortical area in combination with anode polarization of mammillary bodies. Acetylcholine, which separate effect was connected with a restricted increase of the spatial synchronization of potentials, completely eliminated the effects of isolated polarization expressed in a significant decrease of a half of calculated correlation coefficients between EEGs of the visual and motor cortical areas. Nonspecific cholinergic synchronizing system is supposed to exist which is active under the conditions of the mammillo-thalamo-cortical connections being intact.
为研究胆碱能递质系统在维持边缘系统同步影响中的作用，在将乙酰胆碱溶液应用于视觉皮质区并结合乳头体阳极极化的情况下，评估了由24个电极引导的兔脑电图互相关系数变化的空间分布动态。乙酰胆碱单独作用时与电位空间同步的有限增加有关，它完全消除了孤立极化的影响，孤立极化的影响表现为视觉和运动皮质区脑电图之间计算出的相关系数有显著一半的下降。推测存在非特异性胆碱能同步系统，该系统在乳头体 - 丘脑 - 皮质连接完整的条件下活跃。
