_____ is required for normal brain maturation to occur.

A) Experience-expectant growth
B) Experience-dependent growth
C) Self-righting
D) Head-sparing

Experience-expectant growth refers to the process where the brain develops in response to expected experiences in the environment during critical periods of development. This process is necessary for normal brain maturation to occur. Experience-dependent growth, on the other hand, is the process by which the brain forms neural connections in response to unique experiences and is not necessary for normal brain maturation. Self-righting refers to the innate ability of the body to correct imbalances and return to a normal state, while head-sparing refers to the preservation of brain function during malnutrition.
