In chronic experiments on five dogs with stomach fistulas and bipolar electrodes (6-8 pairs) symmetrically implanted in the cranial bones we recorded simultaneously the activity of the stomach balloonographically and the electroencephalogram using the Nikhon Koden encephalograph with automatic analysis of the frequency spectrum within five ranges: 2-4, 4-8, 8-12, 12-20, and 20-30 oscill/sec. The correlation between the frequency spectrum of the EEG and the phases of periodic activity (PA) cycles of the stomach in the form of a regular shift in the predominance of fast (during contraction periods) or slow (during resting periods) components and its changes under the influence of atropine and food stimulants have been described. The EEG complexes typical of periods of contraction or resting are regarded as cortical correlates of the PA under conditions of good adaptation of the animals to the experimental situation. The changes in the correlation under conditions of actions used indicate a firmer association between the PA EEG correlates with other components of the PA rather than with the motor function of the stomach.
在对五只患有胃瘘且颅骨对称植入双极电极（6 - 8对）的狗进行的慢性实验中，我们使用尼康光电脑电图仪，同时通过胃气囊造影记录胃的活动，并记录脑电图，该仪器能自动分析五个频率范围内的频谱：2 - 4、4 - 8、8 - 12、12 - 20和20 - 30次振荡/秒。已经描述了脑电图频谱与胃的周期性活动（PA）周期各阶段之间的相关性，表现为快速成分（收缩期）或慢速成分（静息期）优势的规律性变化，以及在阿托品和食物刺激影响下的变化。在动物对实验情况良好适应的条件下，典型的收缩期或静息期脑电图复合体被视为PA的皮质相关物。所采用的作用条件下相关性的变化表明，PA的脑电图相关物与PA的其他成分之间的关联比与胃的运动功能之间的关联更紧密。
