Question

the biomedical technique in which a part of the brain is destroyed with electric current is known as
a. electroconvulsive therapy
b. prefrontal lobotomy
c. bilateral cingulotomy
d. tardive dyskinesia
please select the best answer from the choices provided
o a
o b
o c
o d

Explanation:

• Electroconvulsive therapy (A): Uses electric currents to induce a seizure, not to destroy brain parts.
• Prefrontal lobotomy (B): Involves destroying part of the brain (prefrontal cortex) with electric current (historically).
• Bilateral cingulotomy (C): Targets the cingulate gyrus, usually via surgical lesions (not just electric current - more modern, precise methods).
• Tardive dyskinesia (D): A side - effect of certain medications (involuntary movements), not a brain - destroying technique.

So, the answer is B as it matches the description of destroying a part of the brain with electric current (in its historical context).

Answer:

B. prefrontal lobotomy
