Summary of the data.

Data Collection: The data presented here represent the responses of V1 populations of neurons to natural image sequences.  Visual stimulation was performed as described in below.  A description of surgical procedures, anesthesia, and the insertion of the arrays can be found in this paper.  All recordings were performed on Old-world monkeys (Macaca fascicularis) in primary visual cortex (area V1).  Receptive fields were between 2 and 6 degrees in eccentricity. 

Visual stimulus:  Natural image sequences were generated by digitally sampling commercially available videotapes in VHS/NTSC format. A Silicon Graphics R10000 Solid Impact was used to sample frames at a spatial resolution of 320 × 240 pixels and at a temporal rate of 30 Hz. Thirty different segments of approximately 30-s duration were sampled from four different movies (Sleeper, Benji, Goldfinger and Sheakespere in Love), making a total of 20 minutes of video.

Additional details are in this document.

Format of the data.

The data consists of two main parts: stimulus files (which are jpeg images of the movie frames) and the neuronal responses which are in Matlab format.  Details are in the document linked to above.  Total space for all files is about 1.9GB.
