This archive contains two data files from individual subjects performing a fixation task. Recordings are from visual area V4 using a Utah Array. It also contains a set of functions in matlab that describe the data file format (readme.m), perform simple analysis (example_script.m), and generate the movies shown to the subjects (showplaid.m). All of the data is in Matlab-format .MAT files. The larger files contain 96 channels of LFP in addition to spikes, as well as eye movements and pupil diameter. The smaller .MAT files only contain the spiking data.
