Given the cascade of events leading to ischemia-produced brain damage, __________ antagonists administered immediately after a stroke might reduce the development of brain damage.
A) GABA
B) glutamate
C) acetylcholinesterase
D) dopamine
E) serotonin

Question

Quizplus · Accepted Answer

Glutamate is a neurotransmitter that is released in excessive amounts during ischemia (lack of blood flow) in the brain, leading to excitotoxicity and cell death. Therefore, administering glutamate antagonists immediately after a stroke may reduce the development of brain damage. GABA, acetylcholinesterase, dopamine, and serotonin do not play as direct of a role in the development of ischemia-produced brain damage.
