Exposing mice to ketamine or 60 Hz light flicker causes microglia to remove perineuronal nets around inhibitory neurons, re-opening juvenile-like plasticity. 40 Hz flicker does not remove these nets.

Mice exposed to 40 Hz light and sound during chemotherapy show less DNA damage, inflammation and myelin loss; cognitive performance and myelin integrity improve and benefits persist for months.

Brief flashes paired with moving grating stimuli cause V1 neurons in adult mice to reduce responsiveness to the grating long after stimulation, and this behavioral change depends on NMDA receptors.

The roXiva stroboscopic device uses rhythmic light pulses to produce deep trance and psychedelic‑like experiences with closed eyes, encouraging brainwave entrainment and personal transformation without drugs.

Transcranial alternating current stimulation at 20 Hz makes emotional predictions more stereotypical, indicating beta-band oscillations carry predictions while gamma conveys prediction errors.

Viewing a flickering black‑and‑white chequerboard increases cerebrospinal fluid flow once the pattern stops, suggesting visual stimulation can activate the brain’s glymphatic waste‑clearing system during wakefulness.

Slow‑wave sleep promotes pulses of growth hormone; volunteers taking ritanserin to boost slow‑wave sleep show increased delta power and enhanced hormone secretion, linking delta waves and hormone release.

A 10 Hz audiovisual entrainment session before bed increases sleep time by about an hour and reduces chronic pain, fatigue, depression and anxiety, showing feasibility of smartphone‑based entrainment.

Exposure to 40 Hz flicker enhances EEG power over the occipital cortex and alters microstate coverage and complexity in healthy adults, hinting at potential therapeutic applications for brain disorders.
