Spontaneous unit activity in alert unrestrained rabbits was recorded simultaneously with two microelectrodes from the visual and sensorimotor cortex. The correlation analysis revealed that activity of majority of the neurons had no regular rhythm. But spectral analysis of the average correlograms showed existence of oscillations in the delta- and theta-ranges. The synergic type of interaction between cortical neurons was prevalent. Analysis of structure of the distant interaction showed the reduced probability of synergic spikes with periods 150-200 msec and less and the increased one with periods within 200-500 msec.
用两个微电极同时记录清醒无拘束家兔视觉皮层和感觉运动皮层的自发放电活动。相关性分析显示，大多数神经元的活动没有规则节律。但对平均相关图的频谱分析表明，存在δ波和θ波范围内的振荡。皮层神经元之间的协同相互作用类型较为普遍。对远距离相互作用结构的分析表明，周期为150 - 200毫秒及更短的协同放电概率降低，而周期在200 - 500毫秒内的协同放电概率增加。
