Detailed explanation-1: -By analyzing intracranial electrode data from humans, we demonstrate for the first time that there are prominent beta (15–35 Hz) and theta (4–8 Hz) oscillations in both the anterior cingulate cortex (ACC) and the DLPFC during REM sleep.
Detailed explanation-2: -Stage R: Alpha and Beta Waves During the REM sleep stage, we have very similar brainwaves to when we are awake. Our brain exhibits mixed frequency brain wave activity, most likely due to our dreams.
Detailed explanation-3: -Indeed, they distinguished two groups of delta waves occurring during REM sleep: slower (<2 Hz) waves, recorded in medial-occipital regions, present in both NREM and REM sleep, and faster (2.5–3 Hz), REM-sleep-exclusive, fronto-central/occipito-temporal “sawtooth” waves.
Detailed explanation-4: -Beta waves oscillate between about 13 and 35 times per second. Beta waves are prominent during states of concentration and problem solving. Beta waves are common in the EEG’s of most waking adults but may also be present during drowsiness. Beta waves tend to be more visible in the EEG when the patients eyes are open.
