Multi-electrode array recording from salamander retinal ganglion cells

This data was collected as part of the study [1]. It consists of preprocessed multi-electrode array recording from 160 salamander retinal ganglion cells responding to 297 repeats of a 19 s natural movie. The data is available in two formats: (1) a .mat file containing an array with dimensions “number of repeats” x “number of neurons” x “time in a repeat”; (2) a zipped .txt file containing the same data represented as an array with dimensions “number of neurons” x “number of samples”, where the number of samples is equal to the product of the number of repeats and timebins within a repeat. The time dimension is divided into 20 ms time windows, and the array is binary indicating whether a given cell elicited at least one spike in a given time window during a particular repeat. See the reference below for details regarding collection and preprocessing:

本数据集系[1]研究项目所收集。其内容为经预处理的多电极阵列记录，涉及160只蝾螈视网膜神经节细胞对时长为19秒的自然电影297次重复播放的响应。数据以两种格式提供：(1) 一个包含“重复次数”x“神经元数量”x“重复内时间”维度的数组.mat文件；(2) 一个包含相同数据的压缩.txt文件，数据以“神经元数量”x“样本数量”的数组形式表示，其中样本数量等于重复次数与重复内每个时间窗口的时间单元数的乘积。时间维度被划分为20毫秒的时间窗口，数组以二进制形式表示特定重复期间给定时间窗口内是否存在至少一个由特定细胞引发的尖峰。有关数据收集和预处理的详细信息，请参阅以下参考文献：
