Document Summary
In uences on brain and behavior: correlating emerging brain structures with emerging behaviors. Ability to plan ef ciently: correlating emerging behaviors with neural maturation. Thursday, september 29, 2016: identifying in uences on brain and behavior. Neurobiology of development: early in development, all vertebrates look alike, prenatal stages. Neural tube - structure in the early stage of brain development from which the brain and spinal cord develop: major events. Day 49: embryo begins to resemble a miniature person. 7 months: gyri (hills/bumps) and sulci (valleys/cracks) begin to form. 9 months: brain looks like an adult brain. Origins of neurons and glia: stem > progenitor > blast (neuroblasts and glioblasts produced) > specialized (neurons and glia differentiate, glia cells are support cells (ex) coating the axons with myelin, https://faculty. washington. edu/chudler/glia. html. Chemical signal > turns genes on (gene expression) > speci c proteins are made > speci c cells develop.
