An infant will gain control over their neck muscles first, which allows them to hold their head steady. During the next several years,dendrites, or connections between neurons, will undergo a period of transient exuberance or temporary dramatic growth (exuberantbecause itisso rapid andtransientbecause some of it istemporary). Still, studies in mice have found that strategies to boost neurogenesis, such as regular exercise, can improve cognitive function. The myelin sheath that surrounds and protects nerve fibers wears down, which can slow the speed of communication between neurons.

Signaling by one or more of these small GTPases appears to play a role in dendrite initiation, growth and dendrite branching (Luo, 2002; Leemhuis et al., 2004). Some of the studies point to age being less of a factor in cessation of neurological development, with environment (e.g., lack of ongoing learning that could promote maintenance/ growth) being more of a factor.

Huelke D. F. (1998). Myelin helps insulate the nerve cell and speed the rate of transmission of impulses from one cell to another. Once the growth stops, they generate small specialized protrusions known as dendritic spines for nerve impulse transmission. By the time typically developing children are 3 to 5 years old, examples of gross motor development include being able to run, hop, balance on one foot, throw and kick a ball, climb up stairs or playground equipment and ride a tricycle.
