6. ELECTRODE PLACEMENT
Letter for region
F - Frontal Lobe
T - Temporal Lobe
C - Center
O - Occipital Lobe
Number for exact position
Odd numbers - left
Even numbers - right
ELECTRODE PLACEMENT FOR 10-20 SYSTEM [spaced apart 10-20%]
7. BRAIN WAVES
Type 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
