84 region Pattern Pulse mutifocal VEP (PPmfVEP) dart board stimulus.

Pattern Pulse minimizes the simultaneous appearance of two adjacent regions to reduce cortical lateral suppression. The PPmfVEP technique produces improved SNR, relative to the contrast reversing stimulus paradigm, requiring only a four minute run for good SNR. Analysis with linear regression instead of cross-correlation allows for flexibility in stimulus choice and provides statistically efficient estimates of system parameters.
