Nonlinear decoding of a complex movie from the mammalian retina

This package contains data for the publication "Nonlinear decoding of a complex movie from the mammalian retina" by Deny S. et al, PLOS Comput Biol (2018).

The data consists of
(i) 91 spike sorted, isolated rat retinal ganglion cells that pass stability and quality criteria, recorded on the multi-electrode array, in response to the presentation of the complex movie with many randomly moving dark discs. The responses are represented as 648000 x 91 binary matrix, where the first index indicates the timebin of duration 12.5 ms, and the second index the neural identity. The matrix entry is 0/1 if the neuron didn't/did spike in the particular time bin.
(ii) README file and a graphical illustration of the structure of the experiment, specifying how the 648000 timebins are split into epochs where 1, 2, 4, or 10 discs were displayed, and which stimulus segments are exact repeats or unique ball trajectories.
(iii) a 648000 x 400 matrix of luminance traces for each of the 20 x 20 positions ("sites") in the movie frame, with time that is locked to the recorded raster. The luminance traces are produced as described in the manuscript by filtering the raw disc movie with a small gaussian spatial kernel.

本数据包包含了Deny S.等作者发表于PLOS Comput Biol (2018)杂志的论文《从哺乳动物视网膜中非线性解码复杂电影》中的数据。数据包括：(i) 91个经过稳定性与质量评估的、独立分选的鼠视网膜神经节细胞数据，这些细胞在多电极阵列上对随机移动的暗盘组成的复杂电影的呈现产生了反应。响应数据以648000 x 91的二进制矩阵形式表示，其中第一个索引表示持续时间为12.5毫秒的时间间隔，第二个索引表示神经元的身份。矩阵中的条目为0/1，表示神经元在特定时间间隔内未/已发生放电。(ii) README文件和实验结构的图形说明，具体说明了如何将648000个时间间隔划分为显示1、2、4或10个暗盘的epochs，以及哪些刺激段是精确重复或独特的球轨迹。(iii) 每个电影帧中20 x 20位置（“位点”）的亮度轨迹矩阵，尺寸为648000 x 400，时间与记录的raster同步。亮度轨迹通过在原始暗盘电影上应用小的高斯空间核进行滤波生成。
