Neurons in the midbrain receive strong, specific synaptic input from retinal ganglion cells, but only from a small number of the sensory neurons.
During the embryonic stage, tactile information simultaneously activated the tactile and visual neural pathways. After birth, the pathways separate and reorganize to allow for individual processing of visual and tactile information.
Multiple sclerosis-associated retinal layer thinning predicts the severity of future relapses and the likelihood of disability.
Researchers have identified a new type of retinal ganglion cells.
Changes in the Retina Can Be Linked to Parts of the Brain of Healthy Subjects at Risk of Alzheimer’s
In cognitively healthy people with a genetic risk for Alzheimer's, retinal changes have been associated with alterations in the entorhinal cortex, hippocampus, and lingual gyrus. Researchers say retinal changes can be used to track changes in brain structures associated with Alzheimer's in those with genetic risk factors.
The visual system adapts to the loss of photoreception by increasing sensitivity but simultaneously becomes deleteriously hyperactive. The findings could lead to new therapies to protect vision or reverse vision loss.
In mice, photoreceptor cells drive vision and non-vision functions using distinct circuits in the eye.
Measuring the electrical activity of the retina in response to light stimulus could be a biomarker for ADHD and autism, researchers report.
Researchers have identified a new genetic eye disease that affects the macula.
People who experience visual imagination have pupillary responses that optimize the amount of light hitting the retina and change in response to imagined items. This pupillary response does not occur in those with aphantasia.
Focused ultrasound technology that stimulates the retina may help those with blindness to regain their vision.
The ability of retinal cells to "wall off" damage may be key to preserving vision.
