AP PSYCHOLOGY

Detailed explanation-1: -Electroencephalography (EEG) Whereas fMRI records blood flow, a proxy of neuron activation, EEG directly records the brain’s electrical activity via electrodes placed on the scalp of the subject.

Detailed explanation-2: -A key advantage of ERP methods is that they provide measures of neural activity with very high temporal resolution. The superior temporal resolution of ERPs makes them well suited to examinations of neural events responsible for human memory, which can potentially be monitored on a millisecond-by-millisecond basis.

Detailed explanation-3: -An EEG is a test that detects abnormalities in your brain waves, or in the electrical activity of your brain. During the procedure, electrodes consisting of small metal discs with thin wires are pasted onto your scalp. The electrodes detect tiny electrical charges that result from the activity of your brain cells.

Detailed explanation-4: -Magnetoencephalography (MEG) MEG is a sophisticated non-invasive functional neuroimaging technique that measures the external magnetic field generated by the neural activity of the brain. Changes in the neuromagnetic field are a direct and instantaneous reflection of neural events in the brain.
