which contains association areas that integrate information from several sensory modalities, matured last suggesting that the higher-order association areas mature only after the lower-order sensorimotor regions, whose functions they integrate, have matured (Gogtay, Giedd et al., 2004). Time-lapse maps of this developmental trajectory may be seen at http://www.loni.ucla.edu/∼thompson/DEVEL/dynamic.html. To some extent, ontogeny recapitulates phylogeny; the latest developing areas are most recent areas from an evolutionary standpoint, including prefrontal regions involved in executive function, decision-making and inhibition (Puelles & Rubenstein, 2003).
