Retinal visual response properties in awake mice are similar to those under anesthesia or ex vivo, but not exactly the same, so knowledge of retinal function cannot be simply translated from ex vivo to in vivo.
In the retina, the receptive field surround preserves the spatial contrast sensitivity of the center in the face of naturalistic changes in local luminance.
Neurons in the mouse superior colliculus comprise about 20 types based on their responses to visual stimuli, and neurons of the same type tend to cluster together.
Psychophysical measurement and computational modeling show that sensory information cannot contribute directly to a cognitive judgment, but must first be integrated into resource-limited working memory.
Feedforward inhibition generates motion anticipation by selectively decreasing sensitivity to a stimulus as it moves across the latter part of a retinal ganglion cell's receptive field.
Signals from primate rod photoreceptors do not exhibit the light-level-dependent routing through parallel retinal circuits observed in rodents and often invoked in interpreting psychophysical experiments.

Accurate direction-selective information is present within small sections of the dendrites, raising the possibility that single dendrites utilize parallel processing schemes to process motion information.
Cells within the retina synchronize transmitter release across their output synapses in the dark, reducing the impact of noise generated at these synapses and allowing light-dependent signals to be transmitted with minimal added synaptic noise.
The ability to smoothly perceive the environment across saccades without disturbing retinal motion sensations is generated by eye movement contingent habituation.
