Induction of self awareness in dreams through frontal low current stimulation of gamma activity

Nat Neurosci. 2014 Jun;17(6):810-2. doi: 10.1038/nn.3719. Epub 2014 May 11.


Recent findings link fronto-temporal gamma electroencephalographic (EEG) activity to conscious awareness in dreams, but a causal relationship has not yet been established. We found that current stimulation in the lower gamma band during REM sleep influences ongoing brain activity and induces self-reflective awareness in dreams. Other stimulation frequencies were not effective, suggesting that higher order consciousness is indeed related to synchronous oscillations around 25 and 40 Hz.
