Scientists learn more about how inhibitory brain cells get excited

Jan. 30, 2013 — Scientists have found an early step in how the brain’s inhibitory cells get excited. A natural balance of excitement and inhibition keeps the brain from firing electrical impulses randomly and excessively, resulting in problems such as schizophrenia and seizures.
