One reason why cholinergic neurons in the basal forebrain die during synaptic pruning is that they must compete for limited amounts of:
A) radial glial cells.
B) cell adhesion molecules.
C) nerve growth factor.
D) tropic molecules.

Question

Quizplus · Accepted Answer

Cholinergic neurons in the basal forebrain rely on nerve growth factor (NGF) for survival. During synaptic pruning, there are limited amounts of NGF available to support the survival of all neurons, so the competition for this limited resource can result in some cholinergic neurons dying off.
