Gamma Entrainment Improve the Recovery of Awareness

"We expect to screen out the efficacy of Gamma band in the prognosis and treatment of disorders of consciousness by various frequencies of stimulation.~Optical stimulation:~A computer program is used to control the flashing frequency of LED lights for stimulation. The serial port can convert the parallel data characters of the computer CPU into a continuous serial data stream. According to the frequency designed by experiment (10Hz, 20hz, 40hz, 80hz), we modulate the flicker frequency of LED lamp. LED lamp uses T8 lamp, diameter 25.4 mm, length 620 mm, and power 20W.~Acoustic stimulation:~We use Adobe Audition CC 2022 to modulate the tones. The tones modulated to 10Hz, 20Hz, 40Hz and 80Hz are play by noise-canceling headphones to the patients."
