@Marmaduke: EEG-om je moguće razlučiti nekoliko vrsta moždanih valova koje se razlikuju prema frekvenciji. 1. Beta (iznad 12 Hz) je normalno budno stanje. 2. Alfa (8-12 Hz) je stanje opuštenosti i meditacije. 3. Theta (4-8 Hz) je stanje sanjanja, transa i hipnoze. 4. Delta (0,5-4 Hz) je stanje dubokog sna.
There's nothing like the laughter of a baby. Unless it's 1 a.m. and you're home alone.
