Document Summary
Psyc 2p12 chapter 3 notes: infancy- physical & cognitive development. Cerebral cortex: the outer folded mantle of the brain, responsible for thinking, reasoning, perceiving, and all conscious responses. Axon: a long nerve fiber that usually conducts impulses away from the cell body of a neuron. Dendrite: branching fiber that receives information and conducts impulses toward the cell body of a neuron. Synapse: gap between the dendrites of one neuron and the axon of another, over which impulses flow. Synaptogenesis: forming of connections between neurons at the synapses; this process, responsible for all perceptions, actions, and thoughts is most intense during infancy and childhood but continues throughout life. Myelination: formation of a fatty layer encasing the axons of neurons. This process which speeds the transmission of neural impulses, continues from birth to early adulthood. Plastic: malleable, or capable of being changes (refers to cognitive development) Sucking reflex: the automatic sucking movements newborns produce especially when anything touches their lips.
