Final answer:
The correct procedure for treating severe depression with electric current administered to the brain is electroconvulsive therapy (ECT).
Step-by-step explanation:
The procedure used in the treatment of severe depression that involves an electric current being briefly administered to a patient's brain is known as electroconvulsive therapy (ECT). Unlike psychotherapy or pharmacological approaches like taking monoamine oxidase inhibitors or selective serotonin reuptake inhibitors, ECT involves inducing a brief seizure in the patient through an electric current.
This method has proven to be effective for severe depression that does not respond to other treatments. Alongside ECT, other neurological disorder treatments like deep-brain stimulation and transcranial magnetic stimulation utilize electrical or magnetic induction to affect brain activity. However, the correct answer to the multiple-choice question is electroconvulsive therapy.
