Investigation of visual dream reports after transcranial direct current stimulation (tDCS) during REM sleep

This is one of the applications of tDCS I’ve been waiting to hear about. I was hoping tDCS might help facilitate an active dreaming state or even lucid dreaming.

Conclusions
In summary, using two different methodologies it appears that tDCS had no effect on the presence of dream reports with visual imagery or measures of dream quality. However, this may be due to methodological limitations of these stud- ies, as the delivery methods employed allowed only low levels of tDCS to be delivered without waking participants. Improvements allowing higher levels of stimulation during sleep and stimulation of other cortical regions could poten- tially provide more definitive conclusions regarding the ef- fectiveness of tDCS on dream imagery reported from REM sleep.

  1. I am also testing this TCDC method but haven't had the time to actually use it during REM. I think it will work if the current is more than 2mA but it will have to be intervals not left on for long periods. on said:

    Very interested in this TCDC since I already have the timer set-up for light cuing so I just connect this TCDC to the cue.
