Notes

Data file names for this data set begin with either "e", "k" or "r", each indicating a different subject.

Stimulus

The stimulus was a sparse, dynamic random dot pattern (as generally described for data set nsa2004.2) with the constraint that motion coherence was held at 100%. Thus, the dot field translated smoothly behind a circular aperture.

A full description of the stimulus is provided in the papers cited below in Electrophysiological Methods.
