Stage 3 : Differentiation

• Differentiation - refers to the process by which cells in the developing nervous system become specialized to perform specific functions.
• During differentiation, neural stem cells give rise to different types of neurons and glial

  cells.

  • example, some neurons may specialize in detecting light, while others may be responsible for processing auditory information.
• Differentiation - is a crucial process in physiological psychology because it determines the functional properties of the nervous system.
