AP PSYCHOLOGY

Detailed explanation-1: -Electrophysiology is the branch of neuroscience that explores the electrical activity of living neurons and investigates the molecular and cellular processes that govern their signaling. Neurons communicate using electrical and chemical signals.

Detailed explanation-2: -An electrophysiology (EP) study is a test performed to assess your heart’s electrical system or activity and is used to diagnose abnormal heartbeats or arrhythmia. The test is performed by inserting catheters and then wire electrodes, which measure electrical activity, through blood vessels that enter the heart.

Detailed explanation-3: -fMRI measures the cerebral hemodynamic changes which arise from the neuronal activity. The major advantages of this method are the non-invasive basis of the imaging modality as well as the ability to image the entire cerebral volume including deep sources of activity.

Detailed explanation-4: -There are many techniques available to record brain activity-including electroencephalography (EEG), magnetoencephalography (MEG), and functional magnetic resonance imaging (fMRI)-but these do not allow for single-neuron resolution.

Detailed explanation-5: -Electrophysiology: The biomedical field dealing with the study of electric activity in the body. Electrophysiology includes the study of the production of electrical activity and the effects of that electrical activity on the body.
