Tohoku University researchers have discovered a way to monitor blood vessel dynamics in the mouse brain, which can be influenced by visual stimuli.

The novel observation method uses optical fibers to view blood vessel dynamics without invasive procedures.

Visual stimuli with moving stripes can synchronize vasomotion, potentially improving the brain's function by enhancing circulation and waste clearance.

The team suggests synchronized blood flow could aid in cognitive processes, stroke recovery, and delaying neurodegenerative diseases.

The research opens up possibilities for new treatments that utilize vasomotion synchronization to clear brain waste and potentially enhance intelligence.
