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.

Studies at MIT and elsewhere are producing mounting evidence that
light flickering and sound clicking at the gamma brain rhythm
frequency of 40 hertz (Hz) can reduce Alzheimer's disease (AD)
progression and treat symptoms in human volunteers as well as lab
mice. In a new open-access study in Nature using a mouse model of the
disease, MIT researchers reveal a key mechanism that may contribute to
these beneficial effects: clearance of amyloid proteins, a hallmark of
AD pathology, via the brain's glymphatic system, a recently discovered "plumbing" network parallel to the brain's blood vessels.
