Three big ideas from brain science have arisen during the past 20 to 30 years: neural connections form rapidly early in life; critical periods occur in development; and enriched environments profoundly affect brain development during the early years. Current brain research has little to offer educational practice or policy. (10 references) (MLH)

Debunks the "myth of the first three years"--notions about synaptic density changes, critical periods, and "enriched" or complex environments in early brain development. Neuroscientists say synaptic densities vary over the life span. There is no linear connection between number of synapses in the brain and brainpower or intelligence. (Contains 44…
