Evidence that 40Hz gamma stimulation promotes brain health is expanding

A decade of studies provide a growing evidence base that increasing the power of the brain’s gamma rhythms could help fight Alzheimer’s, and perhaps other neurological diseases.

Study: Even after learning the right idea, humans and animals still seem to test other approaches

New research adds evidence that learning a successful strategy for approaching a task doesn’t prevent further exploration, even if doing so reduces performance.

Study suggests how the brain, with sleep, learns meaningful maps of spaces

Place cells are known to encode individual locations, but research finds stitching together a “cognitive map” of a whole environment requires a broader ensemble of cells, aided by sleep, over several days.

To understand cognition — and its dysfunction — neuroscientists must learn its rhythms

A new framework describes how thought arises from the coordination of neural activity driven by oscillating electric fields — a.k.a. brain “waves” or “rhythms.”

How sensory gamma rhythm stimulation clears amyloid in Alzheimer’s mice

Study finds stimulating a key brain rhythm with light and sound increases peptide release from interneurons, driving clearance of an Alzheimer’s protein.
