While some types of excitatory neurons respond to images and represent them in the visual cortex, the activity of two types of inhibitory interneurons combine in a circuit to reinforce visual stability and reliability.

Combining artificial intelligence, mathematical modeling, and brain imaging data, researchers shed light on the neural processes that occur when people use mental abstraction.
Study reveals how decisions based on visual information, which involves a complex stream of data flowing forwards and backward along the visual pathways, are broadcast widely to neurons in the visual system, including those not involved in the decision-making process.
While the visual cortex stores individual images in the brain, the hippocampus plays a significant role in the ability to recognize a sequence of images.
Face pareidolia, a phenomenon where the brain is tricked into seeing human faces in inanimate objects, may occur as a result of the brain processing the perceived facial expression in the same sequential way it perceives a human face.
A newly designed optical illusion is helping researchers better understand visual processing and perception. The illusion creates a subjective reality in what we see, highlighting the constructive nature of perception.
People with hyperphantasia, the ability to visualize vividly, have stronger connections between their visual brain network and decision-making networks. By contrast, those with aphantasia, an inability to visualize, have weaker connections between the brain regions.
New research indicates the existence of an unconscious iconic memory store that supports predictions made by the global workspace theory of consciousness. It also shows that visual masking does not erase memory traces of masked stimuli but only limits conscious access.
Researchers have identified three areas of the posterior cerebral cortex that bridge the brain's perception and memory systems.
