The shape of your brain may strongly influence your thoughts and behavior, study finds

June 1, 2023

(NBC News) – Though much about the brain remains a mystery, scientists have long surmised that our thoughts, feelings and behavior are the result of billions of interconnected neurons that transmit signals to each other, thereby enabling communication between regions of the brain.

But a study published Wednesday in the journal Nature challenges that idea, suggesting instead that the shape of the brain — its size, curves and grooves — may exert a greater influence on how we think, feel and behave than the connections and signals between neurons.
