Tetrode recordings from CA1

Tetrode recordings from CA1.<br><br>The recording sessions used in this study were around 40 min long, depending on the spatial sampling of the animal, in a rectangular environment of 1.75 x 1.25 m, on the second, third or fourth exposure, varying between animals. There was one large cue card raised above the boundary and two smaller cue cards distributed on the side of the boundary. Foraging was encouraged with 20 mg chocolate-flavoured pellets dropped into the environment by custom automated devices.<br>

本研究采用的记录实验时段时长约为40分钟，具体时长取决于动物的空间采样情况。实验环境为1.75×1.25米的矩形空间，记录时段对应动物第二次、第三次或第四次暴露于该环境的场景，不同动物的暴露次数存在差异。环境边界上方设有一张大型提示卡，另有两张小型提示卡分布于环境边界的侧面。研究人员通过定制自动化装置向环境中投放20毫克的巧克力味食物颗粒，以诱导动物开展觅食活动。
