This dynamic, random stimulus consists of two moving Gabor patches that are presented simultaneously at randomized positions on an underlying square spatial grid. It is designed to emulate the stimulus of Britten and Heuer (1999, J Neurosci) that was used to probe the linearity of spatial summation within the receptive fields of neurons in area MT.

In this stimulus, the entire Gabor patch moves, rather than having the phase of the sinusoid shift beneath the Gaussian window.

The stimulus can be run in single-patch mode to measure single-patch responses for computing the linear predictions for comparison to dual-patch responses.
