https://en.wikipedia.org/wiki/Neural_oscillation#Overview says brainwaves are 1-150 Hz? IIRC compassion is acheivable on a bass guitar.

Doodling improves memory retention / learning, too. IDK how much difference the content of a doodle makes? Hypothesis: Additional "cognitive landmarky" content in the doodle or received waveforms would increase retention up to a limit.

" IDK how much difference the content of a doodle makes?"

I'm a doodler. I also make art. And you are right, the cognitive load of the doodle makes a difference. My 'learning doodles' are really a mindless endeavor, and they only realistically look arty because I have been making art for decades now. The actual content of the doodle matters little. The real point is more keeping the hands busy and the mind lightly engaged with something else - I suppose it is akin to listening to a podcast while walking or driving.

I can get something similar from taking notes, but even that is better if I have doodle space since I don't need to write everything down.

Regarding doodling, it seems that any active productive study method is at least somewhat beneficial. I've found this in my own personal experiments. For example, testing myself with cloze deletions, creating Anki cards, generating mind maps, Cornell notes, inline annotation/marginalia, doodling, generating questions, generating mnemonics, mind palaces, etc.

An interesting one is reading and reciting out loud: https://www.tandfonline.com/doi/full/10.1080/09658211.2017.1...

Another non-intuitive method that is helping me a lot is pacing around my house slowly while I read. It goes to show that cognition is an embodied phenomenon. It's unintuitive when intelligence is viewed from the traditional split mind/body paradigm but just take a look at an image of our nervous systems. Those wires to and from our brain and guts wrap around every part of us.

Mnemosyne/Anki, (FreeMind, yEd, Gephi, AtomSpace as-moses, RDF bnodes, ONNX,) mind maps, RestructuredRext, MyST-Markdown, todo.txt (TaskWarrior,), StructuredProcrastination, ActivityWatch, Dogsheep, *-to-sqlite, awesome-quantified-self, https://github.com/woop/awesome-quantified-self

But metrics for actual memory retention? I've heard of TinCan xAPI w/ a LRS. nbgrader, Khan Academy exercises, OpenBadges to demonstrate proficiency,

Awesome. Thanks for the resources. Coincidentally, I stumbled on this research today on the effect of exercise + meditation on word recall: https://hpp.tbzmed.ac.ir/PDF/hpp-9-314.pdf
