Driving a manual transmission may do more than provide a more engaging driving experience. New research from Japan suggests operating a stick shift activates key areas of the brain responsible for memory, attention, and decision-making more than driving an automatic.
The findings come from Professor Ryuta Kawashima of Tohoku University’s Institute of Development, Aging, and Cancer, according to Japanese outlet Best Car Web. Known for developing the science behind Nintendo’s popular Brain Age games, Kawashima found that the sequence of actions required to drive a manual transmission stimulates the brain’s prefrontal cortex, a region linked to higher cognitive functions.
Researchers found that coordinating clutch operation, gear selection, throttle control, and monitoring traffic requires drivers to continuously process multiple tasks at once. This constant mental engagement keeps the prefrontal cortex active, potentially providing a form of everyday cognitive exercise.
