The paper shows that primary visual cortex maintains a luminance-invariant code despite retinal adaptation, through integration of parallel pathways at the geniculocortical synapse.

The paper measures spatial frequency tuning of color and form in mouse V1 and finds that most neurons exhibit unimodal color opponency distributions, consistent with random pooling of photoreceptor signals.

The paper measures photoreceptor input to mouse V1 under different lighting conditions and finds rod and cone contributions vary, affecting temporal frequency and receptive field size.
