PSYCH 2410 Lecture Notes - Jean Piaget, Neural Development, Strabismus
Document Summary
Structures of the brain the neuron continued. Aborization increase in the density of the branches of dendrites, do this to increase the surface area so they can receive more signals. Myelination laying down of the fatty substance on the axon to increase speed of transmission and also insulates so signals aren"t lost. Synaptogenesis process of pruning away surplus connection. Plasticity: the capacity of the brain to be affected by experience (strabismus: experience-expectant plasticity, basic experiences are expected by the individual brain less information needs to be coded by the genes b. If expected experience does not occur, deficits may result and rewiring may occur: congenital blindness, experience-dependent plasticity, neural connections are created and reorganized throughout life as a function of individual experience, expert skills, cellists and violinists. Brain damage and recovery: worst time, earliest stages of prenatal development and in first year. Affects neurogenesis and neuron migration: best time, early childhood.
