In children, inhibits cognitive development, deficiency in iq (10-15 pts) Distinguishes early brain development is the steep increase in synaptic density: number of synaptic connections among neurons. Peak production in our frontal lobes -> reasoning, planning, and creativity. In toddlerhood, frontal cortex are produced at mind-boggling rate of 2 million per second, by age. Peak synaptic density is end of toddler, third birthday. Methods of assessing brain activity- provide evidence of rapid growth.
