New findings from studies in both people and animals are revealing clues about how sensory information and cognitive processes interact in the brain to produce our perception of the world. The findings were presented at Neuroscience 2021, the annual meeting of the Society for Neuroscience and the world’s largest source of emerging news about brain science and health.
Sensory inputs, such as sights, sounds, and touches, yield rich information about the external world. But our perception and interpretation of sensations are heavily shaped by cognitive processes such as attention, expectation, and memory. A better understanding of the neural basis of perceptual phenomena will help clarify both ordinary experiences — such as the ability to pick a single voice out of a noisy background — and disorders in which perception is altered — such as attention-deficit/hyperactivity disorder, autism, schizophrenia, and Alzheimer’s disease.
