Document Summary

Structures of the brain: neurons: basic units of the brain and the nervous system, synapses: connective spaces between neurons, gila: nerve cell that develop and produce myelin to protect and nourish the neurons, the cerebral cortex. Developmental processes: neurogenesis (proliferation of neurons, synaptogenesis (formation of synapses): overproduction (genetic, synaptic pruning (elimination of excess connections, experience-dependent, myelination (insulation) The importance of experience: plasticity: the capacity of the brain to be affected by experience, experience-expectant plasticity: the normal wiring of the brain as a result of general experiences that human infants normally have. Vulnerability: experience-dependent plasticity: neural connections are created and reorganized throughout life as a function of experience that is unique to an individual. Structures of the brain: neurons, synapses, glia, cerebral cortex. Developmental processes: neurogenesis, synaptogenesis, synaptic pruning, myelination. Four fundamental relations: parent"s genotype to child"s genotype (human heredity, conception, the chromosomes. Stretches of dna (deoxyribonucleic acid): the chemical code for development (instructions: multiple births.
