Document Summary
Development: a process of becoming biologically mature, change. Exemplifies nature/nurture debate (cid:1) as a function of age (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) structures (e. g. frontal cortex) (cid:1) places (cid:1) (cid:1) display differential rates of synaptic peak density. Human brain develops slower in relation to other animals. More delayed development later volume of later developing. Subcortical structures largely in place and intact. Overall synaptic density increases but different cortical regions. Around birth, most neurons have migrated to their respective. E. g. visual cortex peak synaptic formation around 3~4 months, maximum density around 4~12 months. Synaptogenesis in the frontal cortex starts around the same time, (cid:1) but synaptic density increases at a much slower rate (cid:1) (cid:1) (cid:1) Maturational account (or stage-like development) (cid:1) roots in piagetian cognitive development, whereby cognitive development is seen as progressing through a sequence of well- defined stages.
