Analysis of information representation and transformation by the soma and dendrite of the hippocampal place cells

由于海马锥体神经元在环境中的特定位置特异性地放电，因此它们被称为位置细胞。然而，最近的研究表明，地点字段可以根据动物刚刚去过的地方、下一步要去哪里以及它目前面临的需求而改变。在本研究中，我进行了一个多方面的实验，在一个恒定的空间环境中，重复暴露于时空或非空间环境中，同时监测许多海马神经元的变化和动态，我成功地监测了海马区位置编码的变化和动态。结果，我发现Place字段中的位置和射击率分别代表了旅程和任务需求的信息。此外，所有信息都可以同时保存在海马区的整体活动中，以形成事件

Since hippocampal pyramidal neurons discharge specifically at a certain location in the environment, they are termed ‘place cell’. However, recent studies indicate that the place field can be changed in relation to where the animal had just been, where it is about to go next and what demand it currently faces. In the present study, conducting a multifaceted experiment in which many hippocampal neurons are simultaneously monitored during repeated exposures to either spatiotemporal or non-spatial contexts in a constant spatial environment, I succeeded to monitor the changes and dynamics of the hippocampal place code. As a result, I found that the location and firing rate within the place field represents the information for journey and task-demand, respectively. Moreover, all of the information can be simultaneously preserved in the hippocampal ensemble activity to form episodes
