Question 1

What does the term 'rise and fall' of postnatal brain development refer to with respect to brain maturational processes?

Accepted Answer

The 'rise and fall' of postnatal brain development refers to some processes that are additive early in life - the 'rise' -and some processes that are subtractive - the 'fall'. Additive processes include the increase in brain volume during infancy, childhood, and adolescence, where brain volume quadruples in size. Another additive process is dendritic arborization, where increases in dendrites of neurons is found. A related process is synaptogenesis, the increase of synapses. A fourth additive process is myelination, where a fatty sheath called myelin grows around neural fibers, providing a faster transmission of information. The 'fall' processes include a period of loss of synapses - called neural pruning. While early in life, the dendritic arborization occurs, as the infant and young child grows, the density of this forest of dendrites becomes less dense, with neural pathways becoming more formed with faster connections.
