Most fish rely primarily on their vision to find prey to feed upon, but a University of Rhode Island biologist and her colleagues have demonstrated that a group of African cichlids feeds by using its ...

Evolution has turned out bizarre and baffling creatures, such as walking fish. It only gets weirder from there. Some of these fish not only walk on the seafloor, but use their leg-like appendages to ...

Two species of small, deep-dwelling fish called pearlsides possess eye cells that break the rules of vertebrate vision, combining features of rods and cones into a single hybrid photoreceptor never ...

Your surroundings may influence your social behavior more than you realize. New research from the Brain Research Institute at ...

Advanced calcium imaging of zebrafish brains is helping researchers discover how sensory stimuli such as sights and sounds are integrated in the human brain. Advanced calcium imaging of zebrafish ...

To complete tasks that require storing relevant visual details for short periods of time, such as solving a puzzle, reading or comparing different objects, humans leverage their so-called visual ...

By Will Dunham WASHINGTON, Feb 18 (Reuters) - For more than a century, biology textbooks have stated that vision among vertebrates - people included - is built from two clearly defined cell types: ...

Visual agnosia is a rare neurological condition in which people are unable to identify objects. People with visual agnosia can see an object, but the brain is unable to recognize it. It can occur due ...

Migraine auras manifest differently, with visual disturbances being the most common, followed by sensory experiences; language difficulties and motor, retinal, or brainstem auras are less frequent.

Fish visual systems represent a remarkable panorama of evolutionary innovation, underpinned by a diverse array of visual pigments and opsin genes. These pigments, central to photoreception, enable ...
