2of2) A shared neural process rhythmically samples these two sources of information multiple times per second, perhaps alternating between them.

A shared theta-rhythmic process for selective sampling of environmental information and internally stored information Selective attention is the collection of mechanisms through which the brain preferentially processes behaviorally important information. Many everyday tasks, such as shopping for groceries, require…

A large brain scan study with contribution from @zvrlab.bsky.social found people with PTSD had less folding in key brain areas linked to fear and decision-making. This may reduce brain efficiency and could speed up age-related brain changes.

Learning makes brain cells work together, not apart A new University of Rochester study could reshape how scientists think about perception, learning disorders, and artificial intelligence.

A new study challenges a long-standing theory in neuroscience and could reshape how scientists think about perception, learning disorders, and artificial intelligence.
