脑电活动在35-85c/S范围内的报道来自许多种恒温动物的鼻脑，以及包括人类在内的食肉动物和灵长类动物的前脑的许多部分。此范围内3个spp的频率的单峰分布。(猫、大鼠、兔)。相称性发生在均值和方差之间。这种振荡活动的基础存在于兴奋性神经元和抑制性神经元集合的反馈突触相互作用中。在40cps附近找到了频率收敛和高幅度的神经基础。突触机制、单峰频谱分布和脑电活动在这一范围内的广泛存在清楚地代表了一种独特的和可识别的脑活动形式。
EEG activity in the 35-85 c/s range was reported from the rhinencephalon of numerous species of homeotherms and from numerous parts of the forebrain in carnivores and primates, including man. Unimodal distributions of frequencies within this range for 3 spp. (cat, rat and rabbit) were recorded. Proportionality occurred between means and variances. The basis for this oscillatory activity existed in the feedback synaptic interactions of assemblies of excitatory and inhibitory neurons. A neural basis for frequency convergence and high amplitude near 40 CPS was found. The synaptic mechanisms, unimodal spectral distributions and widespread occurrence of EEG activity in this range clearly represent a unique and identifiable form of brain activity.
