Document Summary

Accuracy is measured by the number of electrodes placed on the scalp. Eeg a technique for measuring the spontaneous electrical activity of groups of neurons across the brain to different stimulation conditions using electrodes placed on the scalp. Assess the nature of neural and brain maturation and determine those who are at risk for neurological problems. Event-related potentials (erps) a technique for measuring the electrical activity of specific brain areas in response to the presentation of a particular stimulus/action. Technique same at all ages- continuous assessment across development. Both infants and adults exhibit greater activity at the same scalp location for fearful than for either happy or neutral faces, suggesting that the same brain areas are responsible for face processing throughout development. Magnetoencephalography (meg) a technique in which the magnetic field generated by the electrical activity of the brain is measured by sensors placed on the scalp. Skull and scalp are transparent, allowing for clear neuronal activity.
