which of the following techniques involves passing a mild current through the brain to activate certain structures without damaging them?
∘ electroconvulsive tomography (ect)
∘ electrical stimulation of the brain (esb)
∘ deep brain lesioning
∘ magnetic resonance imaging (mri)

Explanation:

• Electroconvulsive tomography (ECT) is a treatment for severe mental illness that induces seizures, not mild activation without damage.
• Electrical stimulation of the brain (ESB) involves passing a mild electrical current to activate brain structures without damaging them, matching the description.
• Deep brain lesioning involves creating lesions (damage) in the brain, so it does not fit "without damaging them".
• Magnetic resonance imaging (MRI) is an imaging technique using magnetic fields, not passing current through the brain.

Answer:

B. electrical stimulation of the brain (ESB)
