Study reveals structural changes of connectivity in the thalamus to other brain areas in those with congenital blindness, providing evidence of brain plasticity. The areas of the thalamus that connect with the occipital lobe in those with blindness are weaker and smaller, giving space to connections in the temporal cortex which are strengthened.
Single neurons conveying visual information about two separate objects in line of sight do so by alternating signals about one object or the other. However, when the two objects overlap, brain cells detect them as a single entity.
Brain changes associated with ASD encompass more areas than previously believed, a new study reports. Researchers identified brain-wide changes in all 11 cortical regions analyzed. The greatest gene drop-offs were found in the visual cortex and the parietal cortex, a brain area associated with processing touch, pain, and temperature information. The findings shed light on sensory hypersensitivity associated with ASD. Additionally, researchers say the RNA alterations associated with ASD are more likely a cause than a result of autism.
Study reveals a hidden order in seemingly random connections between neurons.
The color red is not particularly strong in terms of the strength of gamma oscillations it generates in the brain.
Study reveals how changes in pupil size affect the way we perceive our surroundings.
Using the Dr. Seuss classic, The Lorax, researchers shed new light on how the brain engages during complex audiovisual speech perception. The findings reveal how the brain utilizes a complex network of brain regions involved in sensory processing, multisensory integration, and cognitive functions to comprehend a story's context.
Images of food stimulate a newly discovered population of food-responsive neurons in the ventral visual stream. Researchers believe there may be an evolutionary reason for this neural population that may reflect the significance of food in human culture.
Alzheimer's disease disrupts some forms of visual memory by degrading a newly identified brain circuit that connects the primary visual cortex of each hemisphere.
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.
Inhibitory and excitatory networks in the brain's visual system develop through different processes, even if the organization of the networks is similar.
A new map of the human brain reveals cells, receptors, and gene activity change along the same boundaries.
