WebMay 5, 2024 · Interestingly, additional short-lived increases in short-lived brain wave activity were seen at the peak of the DMT experience and not seen in psilocybin and LSD EEG data. These changes, namely theta waves, correlated with participant reports of complex visionary phenomena and are otherwise classically associated with REM sleep. Theta waves generate the theta rhythm, a neural oscillation in the brain that underlies various aspects of cognition and behavior, including learning, memory, and spatial navigation in many animals. It can be recorded using various electrophysiological methods, such as electroencephalogram (EEG), recorded either from inside the brain or from electrodes attached to the scalp. WebSuccessful memory encoding is marked by increases in 30–100 Hz gamma-band activity in a broad network of brain regions. Activity in the 3–8 Hz theta band has also been shown to modulate memory encoding, but this effect has been found to vary in direction across studies.
