Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Dr. Angelo is interested in both the brain function and physical layout of his patient’s brain. He wants to see which specific regions contribute to particular brain functions using a technique that shows information about blood flow to certain regions in the brain. Which technique should Dr. Angelo use and why?

A	fMRI
B	PET
C	CAT
D	MRI

Explanation:

Detailed explanation-1: -Neurogenesis is the formation of neurons de novo-the hallmark of a developing brain. In an adult animal brain, neurogenesis is said to occur in the lateral subventricular zone (SVZ) and the DG of the hippocampus (Figure 1).

Detailed explanation-2: -Neurogenesis is the process by which new neurons are formed in the brain. Neurogenesis is crucial when an embryo is developing, but also continues in certain brain regions after birth and throughout our lifespan.

Detailed explanation-3: -Since then, work in animal models and people has indicated that adult hippocampal neurogenesis plays an important role in memory formation and that decreases in neurogenesis accompany aging, as well as cognitive loss and the development of Alzheimer’s disease, which affects 10 percent of Americans older than 65.
