This stimulus consists of a grid of drifting sinewave patches. It is designed to emulate the pseudoplaid stimulus of Kumbhani, El-Shamayleh and Movshon (2015, J Neurophys). The demonstration here is done as a binocular stimulus, with opposite motion across eyes, but Kumbhani's stimulus was monocular, which can be achieved by setting the stim_monocular parameter to "left".

Sine gratings at two orientations are displayed in alternating patchdes. The grid size and scale of the patches can be varied to assess pattern motion integration.

This stimulus is a variation of the gabor_grid stimulus type - please see documentation for gabor_grid for a full description of parameters.



None reported.
