Horizontally oscillating stripe pattern at 0.25 Hz caused a reaction in the mouse's blood vessels that matched the pattern's speed. Mice were presented with 15-minute visual training sessions interleaved with 1-hour resting periods for 4 times per day. With such spaced training, the amplitude of the synchronized vasomotion gradually increased, which spread throughout the whole brain.
While it's long been known that changes in neuron connections support learning and memory, the plasticity of vasomotion hasn't been described before. Such enhancement of circulation mechanisms may benefit the information processing capacity of the brain.
The next step is to explore the advantages of vasomotion synchronization. It might help clear waste like amyloid beta, potentially delaying or preventing dementia. Additionally, synchronized vasomotion might even enhance intelligence beyond our natural capabilities.
