ELECTRODE PLACEMENT FOR 10-20 SYSTEM [spaced apart 10-20%]

BRAIN WAVESType Frequency Location Use

Delta <4 Hz everywhere occur during sleep, coma

Theta 4-7 Hz temporal and parietal

correlated with emotional stress(frustration & disappointment)

Alpha 8-12 Hz occipital and parietal reduce amplitude with sensory stimulation or mental imagery

Beta 12-36 Hz parietal and frontal can increase amplitude during intense mental activity

Mu 9-11 Hz frontal (motor cortex)

diminishes with movement or intention of movement

Lambda sharp, jagged

occipital correlated with visual attention
