Updating tracklist took a second. One of the rock covers of Tomorrow, from Annie, magically disappeared over the past day or something.
Earlier R.E.M. query (not the band) didn't even mention the dang delta. Didn't post it but I parroted their theta beta gamma championing. I think that my present disillusionment with AI has a few slaps in the head still to come.
Captured for posterity, here, as this subject remains a bucket list rabbit hole. Found the earlier theta beta gamma sorority as well.
ex1: hertz frequency of r.e.m. sleep
AI Overview
REM sleep is characterized by brainwave frequencies primarily in the theta (4-8 Hz), beta (16-32 Hz), and gamma (>32 Hz) ranges. During this stage, brain activity resembles that of wakefulness, with fast, low-amplitude, and desynchronized oscillations.
Key Brainwave Frequencies in REM Sleep:
- Theta Waves (4-8 Hz): Predominate in the hippocampus and cortex during REM sleep, similar to wakefulness.
- Beta Waves (16-32 Hz): Also prominent during REM sleep.
- Gamma Waves (>32 Hz): Another frequency range active during REM sleep.
- 40 Hz: A coherent oscillation observed during REM sleep, potentially linked to cognitive processes.
- 1.5-3 Hz: A rhythmic hippocampal oscillation specifically associated with REM sleep, according to a study published on PubMed.
- 15-45 Hz: High-frequency bands in this range are also present during REM sleep.
In contrast to NREM (non-REM) sleep:
- NREM sleep, especially deep sleep (NREM stage 3), is characterized by slow, high-amplitude delta waves (typically 0.5-4 Hz).
- REM sleep, with its faster, lower-amplitude oscillations, more closely resembles the EEG activity observed during wakefulness.

ex2: what is delta sleep?
AI Overview
Delta sleep, also known as deep sleep or slow-wave sleep (SWS), is a stage of sleep characterized by slow, high-amplitude brain waves called delta waves. It's the deepest stage of non-rapid eye movement (NREM) sleep and is crucial for physical restoration and bodily recovery.
Here's a more detailed explanation:
- Delta Waves:
Delta sleep is defined by the presence of delta waves, which are the slowest brainwave frequencies, ranging from 0.5 to 4 Hz.
- Deep Sleep:
During delta sleep, the body's heart rate, breathing, and muscle tone slow down, and it becomes difficult to wake someone up.
- Restorative Sleep:
Deep sleep is essential for physical restoration. It's when the body repairs tissues, builds bone and muscle, and strengthens the immune system.
- Occurence:
Deep sleep occurs primarily in the first two sleep cycles of the night, with the longest periods occurring early on, according to sleep experts.
- Importance:
Delta sleep is vital for feeling refreshed and energized upon waking. It's also linked to cognitive functions like insightful thinking, creativity, and memory consolidation, according to the Sleep Foundation.
