the.com/brain waves
your neurons gossiping in rhythm, and the gossip has a frequency.
means brain waves are the rhythmic electrical patterns produced by billions of neurons firing in sync, measurable on the scalp as oscillations grouped by speed.
from first recorded in 1924 by hans berger, a german psychiatrist obsessed with telepathy who instead invented the eeg and accidentally discovered the brain hums at measurable frequencies.
slowest banddelta waves appear during deep dreamless sleep
fastest bandgamma waves link to peak focus, over 30hz
berger's motivehe wanted proof of mental telepathy, not eeg
alpha discoverynamed alpha simply because berger found it first
for instance
hans berger 1924 — recorded the first human eeg in jena, germany
sleep spindles — 12-14hz bursts during stage 2 sleep, aid memory
meditation studies — tibetan monks show unusually strong gamma synchrony, 2004 richardson lab
epilepsy monitoring — spikes on eeg pinpoint seizure origin points
