ABSTRACT Background Transcranial photobiomodulation (tPBM) enhances cognitive and emotional states. We compared continuous‐wave (CW) and pulsed‐wave (PW) tPBM effects on 24 healthy males. Method Participants received 630 nm tPBM at 95 mW/cm2 for 10 min: Sham, CW, or PW (500 Hz). Outcomes were assess...
