The activity of 63 neurones of the dorsal hippocampus field CA1 was studied in unrestrained rabbits in different behaviour and in the course of repetitive afferent stimulation. It has been found that changes in the mean frequency of spontaneous activity of most neurones (90%) correlate with the kind of the animal's behaviour. Replacement of calm alertness by an active state is primarily attended with enhanced mean frequency of firing. Two types of response dynamics to a repetitive stimulation were revealed: 1) successive decrease of reaction and 2) gradual augmentation and subsequent drop. As stimulation went on most of the neurones revealed a change in the nature of responses: diffuse phasic and tonic reactions were replaced by structured responses of a specific type. The data obtained are regarded as proof of the hippocampus involvement in the organization of integrated orienting behaviour.
在自由活动的兔子处于不同行为状态以及重复传入刺激过程中,对63个海马背侧CA1区神经元的活动进行了研究。结果发现,大多数神经元(90%)自发活动平均频率的变化与动物的行为类型相关。从平静警觉状态转变为活跃状态时,主要伴随着放电平均频率的增加。揭示了对重复刺激的两种反应动力学类型:1)反应连续降低;2)逐渐增强随后下降。随着刺激持续进行,大多数神经元的反应性质发生了变化:弥漫性的相位和紧张性反应被特定类型的结构化反应所取代。所获得的数据被视为海马体参与整合定向行为组织的证据。
