| Key points | Current stimulation in the lower gamma band during REM sleep altered ongoing brain activity and induced self-reflective awareness in dreams, while stimulation at other frequencies was not effective. The authors suggest this supports a link between higher-order consciousness and synchronous oscillations around 25 and 40 Hz. |
Abstract
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.
