Reversible lesions can be produced by microinjection directly into the target brain structure of

B) lidocaine.
C) a coolant.
D) all of the above
E) both A and B

Question

Quizplus · Accepted Answer

Local anesthetics (such as lidocaine) can temporarily block neuronal activity in a specific area and coolants (such as ethanol or a fine-tipped cryoprobe) can also produce reversible lesions by reducing the temperature in the targeted area. Therefore, options A and B (local anesthetics and lidocaine) and C (a coolant) are all capable of producing reversible lesions. Option D is incorrect as it includes all the options, even those that are not relevant to the question.
