How Excitation Inhibition Ratio Shapes Brain Development and Cognition

A new study reveals that a balanced ratio of neural excitation (E) and inhibition (I) is crucial for brain development and cognitive performance. Researchers found that lower E/I ratios in children correlate with better memory and intelligence. This balance is vital for preventing brain disorders and was measured using a novel AI and MRI technique. The findings could inform personalized treatments for mental health conditions.
