Non-Invasive Techniques
Electroencephalography (EEG):
- electrodes placed at scalp to record signals
- reflection of sum of postsynaptic potentials
- cannot record signals from tangential to scalp/deep inside the brain
- poor spatial resolution (cm), great temporal resolution (ms)
Conditions
- weak signals, need amplification/processing and avoid movements
- cap with recording electrode along with position references: mastoids (behind ear), nasion (on top of nose), inion (base of skull) -- to measure skull circumference
