The coding of uniform colour figures in monkey visual cortex (original) (raw)

This study investigates the neural coding of uniform colour figures in the visual cortex of monkeys, highlighting a notable difference between colour representation at the cortical level compared to the lateral geniculate nucleus (LGN). While LGN cells react strongly to diffuse light of specific colours, most cortical neurons show a weak response, activating primarily at the borders of colour fields rather than their interiors. The findings challenge existing assumptions about surface colour representation and suggest that cortical processing involves complex interactions between colour and edge signals, with implications for understanding visual perception mechanisms.
