And, even if new neurons do appear later in life, scientists dont know if they could integrate into long-established brain networks or affect cognition. In fact, certain cognitive abilities improve in middle age: the Seattle Longitudinal Study, which tracked the cognitive abilities of thousands of adults over the past 50 years, showed people actually performed better on tests of verbal abilities, spatial reasoning, math, and abstract reasoning in middle age than they did when they were young adults. Of course, this is not fully accomplished in infancy and toddlerhood but continues throughout childhood and adolescence. government site. Then, in our 30s and 40s, the brain starts to shrink, with the shrinkage rate increasing even more by age 60. [2] Imagine how difficult it must be to raise ones head during the first year of life!

Dendrites are projections of a neuron (nerve cell) that receive signals (information) from other neurons. Although scientists once thought neurogenesis came to a halt after birth, we now know that two brain regions continue to add new neurons throughout life: the olfactory bulbs and the dentate gyrus of the hippocampus. From birth until age 2, dendrites in the cortex increase. What are three primary 3 focus on the gross motor development of children?
