Information about the data including cells, stimuli, format of the data.

Summary of the data

This data consist of multi-electrode recordings from V1 in anesthetized macaque monkeys, while natural images and gratings were flashed on the screen. Recordings were performed using the “Utah” electrode array.  Natural images were presented at two sizes, 3-6.7 degrees and windowed to 1 degree, to quantify surround modulation. Experimental procedures and stimuli are fully described in the associated paper:

Format of the data

Data from ten recording sessions is provided. They are stored in mat files, with names ranging from 01.mat to 10.mat. The data was recorded from three animals. Data includes both the neural recordings and the image stimuli. Total data size is about 300MB. The format of the data are described in the data description document listed at the end of this page.
