In the development of the cerebral cortex
A) internal genetic factors control all differentiation.
B) external inducing factors control all differentiation.
C) a combination of internal genetic factors and external inducing factors control differentiation.
D) neither internal genetic factors nor external inducing factors appear to play a role in differentiation.

Question

Quizplus · Accepted Answer

The development of the cerebral cortex involves both internal genetic factors and external inducing factors. The genetic factors provide a basic blueprint for the overall organization and differentiation of the cortex, but specific cell populations and connections are also influenced by external cues such as signaling molecules and electrical activity. Therefore, a combination of internal and external factors control differentiation.
