Scientists learn more about how inhibitory brain cells get excited
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. However excitement is required to put on the brakes.
“When the inhibitory neuron is excited, its job is to suppress whatever activity it touches,” said Dr. Lin Mei, Director of the Institute of Molecular Medicine and Genetics at the Medical College of Georgia at Georgia Regents University and corresponding author of the study in Nature Neuroscience.
Mei and his colleagues found that the protein erbin, crucial to brain development, is critical to the excitement.
