Of mice and human interneurons: A Q&A with Moritz Helmstaedter

by  /  1 August 2022

People’s brains have a larger network of inhibitory interneurons than mouse brains do, according to a new study. Changes to that network could contribute to autism or other conditions, says lead investigator Moritz Helmstaedter.
