ELECTROPHYSIOLOGY OF LIMBIC NEURONS

海马区(下丘、丘前、 下丘后、下丘旁、内嗅皮层和虹周皮质)将 被记录在自由活动的老鼠身上。一个基于电视和计算机的系统将是 被开发用来测量神经元的放电作为头部方向的函数， 放置和头部方向、位置和速度，头部从侧面旋转 侧身，头部抬高和俯仰。控制这些的刺激 我们将研究射击的空间感觉-行为关联。开始射击 将对不同的环境进行研究，以寻找 环境，以及这些一致性可能被破坏的方式。 对被研究神经元投射的电生理学研究将 被创造出来。慢波节律及其与细胞放电的关系 我们将研究西塔节奏。

Single neurons in the parahippocampal region (subiculum, presubiculum, postsubiculum, parasubiculum, entorhinal cortex and perirhinal cortex) will be recorded in freely moving rats. A TV-computer based system will be developed to measure firing of a neuron as a function of head direction, place and head direction, place, and speed, turning of the head from side to side, and head elevation and pitch. The stimuli which control these spatial sensory-behavioral correlates of firing will be studied. Firing in different environments will be studied looking for constancies across environments, and ways in which these constancies can be disrupted. Electrophysiological studies of the projections of the neurons studied will be made. The slow wave theta rhythm and the relation of cell firing to the theta rhythm will be studied.
