Overview

• Researchers tracked one individual's brain and behavior over five months using brain scans and wearable devices.
• The study identified two response patterns: a short-term wave under seven days and a long-term wave lasting up to fifteen days.
• Physical activity and heart rate variability were found to positively affect brain connectivity, enhancing memory and cognitive flexibility.
• Subtle changes in mood and heart rate can leave lasting imprints on brain function for up to fifteen days.
• The research suggests potential for personalized mental health care by linking brain activity with physiological and environmental data.
