Abstract

Visual motion processing is strongly susceptible to adaptation. Is this effect specific to the pattern type, or does it transfer between pattern types? Based on the N2 component of motion-onset visual evoked potentials, we assessed three commonly used patterns, namely random dots, barcode-like gratings, and sinusoidal gratings. Isodirectional and antidirectional adaptation were used to differentiate between the actual motion adaptation and associated flicker adaptation. Motion adaptation was almost 2.5-fold stronger (P < 0.01) if the same rather than different pattern types were used for adaptation and test. This implies that separate neural populations are involved, suggesting the presence of pattern-tuned motion mechanisms.
