This dataset contains all the spikes of the cells recorded in the study entitled "Neural correlates of distinct levels of predatory threat in dorsal periaqueductal gray neurons." The Matlab struct can be opened with MATLAB software, and it contains six attributes. The first is "cell_number", which indicates what cell the data refers to, and the second is "animal_number", which shows what animal. The third attribute is "Data", which contains ten lines, each representing 10 minutes of recordings in a vector with 600k columns (one for each millisecond) that are zero if there are no spikes and one if the spike is present in that millisecond. The first two lines are the recordings in the neutral environment, the third and fourth are for the plush condition, the fifth and sixth for the cat condition, the seventh and eighth are for the post-cat, and the night and tenth are for the contextual environment. The three last attributes in the struct "freezing", "defence", and "exploration" refers to the behaviors that the animals are exec本数据集包含题为《背侧中脑导水管周围灰质神经元在不同等级捕食威胁下的神经相关性》的研究中所记录的全部神经元锋电位（spikes）。该数据集以MATLAB结构体格式存储，可通过MATLAB软件打开，共包含6个属性字段。第一个字段为`cell_number`（细胞编号），用于标识该数据对应的神经元；第二个字段为`animal_number`（动物编号），用于标识对应实验动物。第三个字段为`Data`，内含10组记录数据。每组数据为一个含600,000列的向量，对应10分钟的连续记录（每一列代表1毫秒）；向量元素为0时表示该毫秒无锋电位，为1时表示该毫秒存在锋电位。10组数据中，前两组为中性环境下的记录；第三、四组为毛绒玩具刺激条件下的记录；第五、六组为猫刺激条件下的记录；第七、八组为猫刺激后阶段的记录；第九、十组为情境环境下的记录。结构体剩余的三个字段分别为`freezing`（僵滞行为）、`defence`（防御行为）与`exploration`（探索行为），对应实验动物所表现出的各类行为（原文表述未完整）。
