Temporal nulling of induction from spatial patterns modulated in time

Résumé

Asymmetric color matching demonstrates that receptive-field organization accounts for large color shifts induced by chromatic patterns (Monnier & Shevell, 2003, 2004). Here, we used temporally-varied chromatic inducing light to infer receptive-field organization using a method that does not require color matching. The shifts in color appearance from temporally varied inducing light were consistent with the same +s/-s spatially antagonistic neural receptive field described in previous work. The response of this type of receptive-field, which is found only in the visual cortex, increases with S-cone stimulation at its center and decreases with S-cone stimulation in the surround. The measurements also showed a negligible influence of temporal inducing frequency from 0.5 to 4 Hz.
