Document Summary
Difference is in how you process the data a. ii. Brain-generated electrical activity is by-produce of neuronal communication and can be measured by elctrodes on the surface of the scalp a. iii. Scalp recorded electrical activity reflects summed activity of many thousands of neurons a. iii. 1. Works well for surfaces closer to scalp a. iv. Neural nets: sponges soaked in potassium-chloride and are conducting, put it on the head and make sure you are getting a good signal from all electrodes a. v. Eeg pattern changes as behavior changes (different state of arousal) a. vi. 1. Tells you how engaged that region of the brain is a. vii. Eeg power: prism white light parsing into rainbows a. vii. 1. Eeg can parse out each type of wave in the brain hinting at kids engagement a. vii. 2. Myelination leads to more high wave neural maturity a. vii. 2. a. Good for seeing if kids at high risk are on track for their age group a. viii.
