Extracellular recordings from monkey hippocampus performing a virtual navigation task

The dataset is made of 189 cells recorded in the hippocampus from two Rhesus macaques.
Recordings were made extracellularly with either single tungsten electrodes or 16
contact u-probes. Activity was recorded as animals were navigating via a joystick
a virtual maze projected in stereo, searching for a reward. A file contains the
timestamps of the action potentials, the X,Y position and camera orientation in
virtual coordinates, the left and right eye X,Y coordinates, state space coordinates
and task relevant event codes. Each file corresponds to a recording session of
approximatively 40 minutes.
We provide a few Matlab scripts and documentation that allow plotting heat maps
according to position, camera orientation, state space as well as raster histograms
and behavior.

本数据集包含从两只恒河猴（Rhesus macaques）的海马体（hippocampus）中记录的189个神经元细胞。记录采用细胞外方式完成，所用设备为单钨丝电极（single tungsten electrodes）或16触点u型电极探针（16-contact u-probes）。实验期间，动物通过操纵杆在立体投影的虚拟迷宫中导航并搜寻奖励，研究人员同步记录其神经活动。单个数据文件涵盖以下数据：动作电位（action potentials）的时间戳、虚拟坐标系下的X、Y位置与相机朝向坐标、左右眼的X、Y坐标、状态空间坐标，以及任务相关事件编码。每个文件对应一段时长约40分钟的记录会话。本数据集附带若干Matlab脚本与配套文档，可支持基于位置、相机朝向、状态空间绘制热图（heat maps），同时可生成脉冲点阵直方图（raster histograms）及行为相关分析图表。
