How does experience alter our perceptions? This adapted book excerpt from We Know It When We See It describes how the brain’s visual system rewires itself to make the best use of its neural resources.
Activity in the visual cortex and other sensory areas is dominated by signals about body movements, down to little tics and twitches. Scientists are now rethinking how they study and conceive of perception.
Researchers have discovered a surprising mathematical relationship in the brain’s representations of sensory information, with possible applications to AI research.
Beneath our awareness, the brain lets certain kinds of stimuli automatically capture our attention by lowering the priority of the rest.
A brain circuit that suppresses distracting sensory information holds important clues about attention and other cognitive processes.
