There is some discussion on the Forum at the moment on the possible use of external electrical stimuli to the head to help PwP.

For some time now, I've been looking at a related area: sensory stimulation. This started with strobe lighting effects, as described above. I've now added audio effects to the program. The sounds are stereophonic, with each channel linked to the corresponding left/right strobe effect.

(Note: to work the program requires a modern browser supporting HTML 5: Chrome is fine, IE8 is not.)

I've set the parameters to default to the ones I use (with the exception that I've set the duration to 10 seconds, while I use 300 seconds).

STROBE EFFECTS ARE DANGEROUS FOR SOME PEOPLE.

ONLY IF YOU KNOW YOU ARE NOT ONE OF THESE PEOPLE:
