A treatment for severe depression in which an electric shock is delivered to the patient, resulting in a seizure of the body and the release of a flood of neurotransmitters in the brain, is called __________

A) prefrontal lobotomy.
B) electroconvulsive therapy.
C) trephining.
D) relaxation training and meditation.

The description given matches the procedure of electroconvulsive therapy (ECT), in which an electric shock is delivered to the patient, resulting in a seizure of the body and the release of a flood of neurotransmitters in the brain. A prefrontal lobotomy involves surgically cutting or removing part of the prefrontal cortex of the brain, and trephining involves drilling a hole in the skull. Relaxation training and meditation are non-invasive and non-pharmacological treatments for mental health issues, but they do not involve electric shocks or seizures.
