A new theory suggests the brain understands the level of activation required from a sensory input and corrects for it, leaving behind a signal for familiarity.
A new study sheds light on visual development and learning in children. Researchers found cortical recycling in the ventral temporal cortex reflects adjustments to changing visual demands throughout childhood.
Prediction errors play a role in the context of dynamic perceptual events that take place within fractions of a second. Findings support the hypothesis that visual perception occurs as a result of a decision process.
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.
Study may provide key insights into the visual system and perception.
Researchers report our ability to identify and categorize visual information is an active process similar to memory stabilization.
Gestures and visual animation assist in allowing us to understand the cognitive origins of linguistic meanings.
