Ripples in rats’ brains tied to memory may also reduce sugar levels

The results suggest brain cell activity could play a surprising role in the body’s metabolism

Bursts of activity created by nerve cells in the hippocampus (computer drawing shown), called sharp-wave ripples, are thought to solidify memories. These ripples may also lower sugar levels elsewhere in the body, a study in rats suggests.

Ripples of nerve cell activity that lock in memories may have an unexpected job outside of the brain: Dropping blood sugar levels in the body.
