Tetrode recording of rat CA1 place cells in an observational spatial working memory task

Social observation facilitates spatial learning by activation of hippocampal place cell patterns. Here, we describe an observational spatial working memory task to investigate the neural circuits underlying observational learning. This approach trains observer rats to learn to run a T-maze by observing a demonstrator’s spatial trajectory while recording their hippocampal CA1 place cell activities in a course of several hours. The protocol provides a tool to study neural activities at population level in a social setting. For complete details on the use and execution of this protocol, please refer to Mou et al. (2021).
