Document Summary
Chapter 6 the child"s growth: brain, body, motor skills, and sexual maturation. In the prenatal period, the brain grows very rapidly, and it continues to grow at an amazing pace. Some glial cells are responsible for the important task of myelination: neural migration: the movement of neurons within the brain that ensures that all brain areas have a sufficient number of neural connections. At birth in the brain"s visual cortex alone, there are 2500 synapses for every neuron. = one quadrillion synapses in the adult human brain. Sequential development of the brain: huttenlocher (1994) found that the processes of forming and pruning synapses occur at different times for various parts of the brain. As baby moves from mostly reflexive behaviour in the early months of life to voluntary control over movements, the motor area of the brain develops most rapidly.
