When the color of a visual stimulus is changed, neurons in the lateral geniculate nucleus and non-oriented cells in the primary visual cortex (V1) of the monkey behave linearly in the color space. This indicates that these neurons combine signals from different types of cones linearly. A major difference between cells in these two structures is the increase of variability of the weights on the inputs from different types of cones seen in V1. In contrast, in the inferior temporal cortex, the behavior of many color selective neurons in the color space is highly non-linear. Such deviation from linear to non-linear behavior seems important to generate a sharp sensitivity to particular hues.
