To understand how they work, it's easiest to start from the beginning, in 1943, when neurophysiologist Warren McCulloch and mathematician Walter Pitts used math to describe the function of neurons in animal brains.

«By learning how tau spreads, we may be able to stop it from jumping from neuron to neuron,» said Karen Duff, PhD, professor in the department of pathology and cell biology (in the Taub Institute for Research on Alzheimer's Disease and the Aging Brain) and professor of psychiatry (at New York State Psychiatric Institute.)

Stanford University researchers studying how the brain controls movement in people with paralysis, related to their diagnosis of Lou Gehrig's disease, have found that groups of neurons work together, firing in complex rhythms to signal muscles about when and where to move.

However, this damages the axons — the arms that protrude from neurons to make connections with other cells — making it difficult to see exactly how brain cells link up.

Previously, researchers had two theories about how neurons in the motor cortex might control movement: One was that these neurons fired in patterns that represent more abstract commands, such as «move your arm to the right,» and then neurons in different brain areas would translate those instructions to guide the muscle contractions that make the arm move; the other was that the motor cortex neurons would actually send directions to the arm muscles, telling them how to contract.

«What we discovered in our preclinical work is evidence of how groups of neurons coordinate and cooperate with each other in a very particular way that gives us deeper insight into how the brain is controlling the arm,» Shenoy said.
