Dominant of thirst was elaborated in water-deprived rabbits by sound stimuli. One judged about the formation of the dominant by a regular appearance of the swallowing or chewing reactions in response to testing stimulations. Spectral analysis of the brain electrical activity revealed a generalized lowering of the spectral power of the potentials of the studied cortical and subcortical areas all over the analysed frequency range. The paraventricular nucleus, the lateral preoptic and anterior hypothalamic areas, in spectrograms of which an increase of estimations in the slow frequency range took place, were an exception. Analysis of the electrical activity recorded at different moments of the dominant manifestation (the tonic state of dominant and that immediately before the summation movement) showed that to each of these dominant states corresponded an appropriate maximum in the theta-frequency range, probably reflecting different levels of motivational-emotional excitation.
通过声音刺激在缺水的兔子身上阐述了口渴优势。通过对测试刺激做出的吞咽或咀嚼反应的规律出现来判断优势的形成。对脑电活动的频谱分析显示，在整个分析频率范围内，所研究的皮质和皮质下区域电位的频谱功率普遍降低。室旁核、视前外侧和下丘脑前部区域是例外，在其频谱图中，低频范围内的估计值有所增加。对在优势表现的不同时刻（优势的紧张状态和紧接总和运动之前的状态）记录的电活动分析表明，这些优势状态中的每一种都对应于θ频率范围内的一个适当最大值，这可能反映了动机 - 情绪兴奋的不同水平。
