New findings reverse hypothesis of GABA neurodevelopment in schizophrenia

A new study published in Biological Psychiatry found that chandelier cells, a type of inhibitory nerve cell, are unaltered in schizophrenia patients, challenging prior findings of GABA deficits. The researchers suspect a developmental origin for the abnormality, which could have implications for treating brain disorders.
