Optic Flow

Optic flow refers to the visual perception of motion in a scene as we move through it. This phenomenon has a significant impact on the nervous system, particularly in reducing anxiety levels by lowering amygdala activity. When individuals engage in forward ambulation, like walking, biking, or running, their eyes naturally track movement from side to side, creating optic flow. This action quiets the amygdala, a brain region associated with fear and anxiety, and stimulates other brain areas, improving overall mental health. Studies have demonstrated that not only do these eye movements help in anxiety reduction, but they also integrate visual-motor responses, enhancing cognitive functions 1.

Further insights by Dr. Huberman highlight the benefits of self-generated optic flow, especially without artificial vehicles like treadmills or motorcycles, in enhancing mood systems and visual health. This activity is easily accessible and does not incur any cost, providing substantial benefits just by engaging in regular movements where the visual field actively changes as you move 2.

By encouraging these simple yet effective behaviors of experiencing optic flow through activities like walking or cycling, individuals can significantly bolster their mental and visual health.
