About v4-1
Summary of the data
These data were collected by Matthew Smith’s laboratory (Carnegie Mellon University). The data include Utah array recordings from visual area V4 of two rhesus macaque monkeys performing a fixation task while a visual stimulus (a sequence of static gratings and plaid stimuli) were shown peripherally in a location centered on the V4 receptive fields. Each fixation included 10 flashed stimuli, shown for 100 ms each, with no blank frames between (a sequence of 1 s total). There was a period of fixation prior to and following this sequence, and then the trial ended with a saccade to a randomly position target. Only correct rewarded trials are included in these data sets.
The data include spike times for single unit activity and multi-unit groups, LFPs, eye position traces, and pupil size traces from 2 animals during this task. Also included are some example code and analysis scripts for this data. The included data represent one session from each animal. The plaids consisted of all combinations of a pair of gratings, 8 orientations (spaced by 22.5 degrees) plus one blank (for a 9x9 fully crossed stimulus set).
Format of the data
The data are stored in matlab format. Details about the data are in the document linked-to at the end of this page. Total data size is about 4.55GB.
