Crashes in visual processing occur when neurons processing one image are tasked with processing another too quickly. This results in either one or both images being unable to reach our conscious awareness.

An asymmetric coupling between the peripheral visual and olfactory sensory systems allows for enhanced steering response to discrete objects in mosquitos.
The human brain can desensitize background motion and focus on smaller moving objects in the foreground as a result of activity in the middle temporal visual area. However, our ability to pick out smaller objects changes over time. Younger people are better at picking out foreground objects moving, while those over 65 have heightened awareness of objects moving in the background.
Two distinct pathways in the visual system allow us to process 3D motion.
People are able to form the correct mental model of puzzles from either visual or haptic experiences alone and are able to predict haptic properties from visual ones. Findings suggest humans segment scenes into objects without explicit boundary cues by using purely statistical information.
Optical illusions are helping researchers better understand attention and visual perception. Findings suggest attention operates periodically on the perceptual binding of visual information.

CT1 cells connect around 1400 areas in the fly brain. Each cell area works like a separate neuron, allowing CT1 to access information from the fly's eye and support local motion detection.
Low-frequency optogenetic stimulation of the visual region of the brain impairs an animal's ability to make fine sensory discriminations.
