Document Summary
Brains are encoded in genes but genes do not includes every instructions for brain assembly and wiring. Brain development is influenced by the environment in the course of the construction phase and by the quality of the materials used. Correlating brain structure and behaviour: as speech emerges, the speech-related structures in the brain thus are undergoing the necessary maturation, same for frontal-lobe development which mature through adolescence. Influences on brain and behaviour: sensory experience, injuries and the actions of hormones and genes, example. Abnormal secretion of a hormone affects both a certain brain structure and a certain behaviour. Neural plate: thickened region of the ectodermal layer that gives rise to the neural tube. Neural tube: structure in the early stage of brain development from which the brain and spinal cord develop. Chapter 8: how does the nervous system develop and adapt? (even though cellular structure is different)
