Answer:

The correct option is B: the expression of NMDA receptors is more abundant in hippocampal than cortical neurons

Explanation:

Global Ischemia is known to cause damage to neurons in distinct areas of the brain. The expression of NMDA, a pattern of selective vulnerability capable of being reproduced is usually seen in the dorsal hippocampal of animals, especially rodents, where the neurons in the CA1 area is mainly affected. Thus, this explains why the hippocampal is the area well faced with a high risk of vulnerability during global ischemia.
