NIH scientists reveal how the brain may fuel intense neural communication
Our thoughts, feelings, and movements are controlled by billions of neurons talking to each other at trillions of specialized communication points called synapses.
Our thoughts, feelings, and movements are controlled by billions of neurons talking to each other at trillions of specialized communication points called synapses. In an in-depth study of neurons grown in laboratory petri dishes, National Institutes of Health researchers discovered how the chattiest of some synapses find the energy to support intense conversations thought to underlie learning and memory. Their results, published in Nature Metabolism, suggest that a series of chemical reactions control a feedback loop that senses the need for more energy and replenishes it by recruiting cellular powerplants, called mitochondria, to the synapses. The experiments were performed by researchers in a lab led by Zu-Hang Sheng, Ph.D., at the NIH’s National Institute of Neurological Disorders and Stroke (NINDS).
