What is the term used to refer to the process of scrambling nerve cells in the brain during early stages of development?

  1. Maturation

  2. Pruning

  3. Differentiation

  4. Synaptogenesis

The correct answer is: Pruning

Pruning is the process of reducing the number of unnecessary neurons and connections in the brain during early development. While maturation, differentiation, and synaptogenesis are all important processes in brain development, they are not specifically related to the scrambling of nerve cells. Maturation refers to the overall growth and development of the brain, differentiation is the process of cells becoming specialized for a specific function, and synaptogenesis is the formation of new connections between neurons. Therefore, B is the best answer as it specifically refers to the process described in the question.
