Researchers trained participants to control pupil size using biofeedback, which activated the locus coeruleus, indicating potential applications for stress and anxiety management.
The technique involved participants utilizing mental strategies to increase or decrease pupil size. They managed to control their arousal response effectively after just three days of training.
By self-regulating their pupil size, participants could influence physiological responses, including heart rate, showcasing the technique's broader implications for emotional and physiological health.
This pioneering approach not only highlights an innovative method for arousal control but also points to novel, non-invasive treatments for anxiety and stress-related disorders.
