PSY 213 Chapter Notes - Chapter 8: Synaptic Pruning, Cerebral Cortex, Dental Caries
Document Summary
Body growth tapers off in early childhood. In the skeleton, new epiphyses emerge, where cartilage hardens into bone. Children begin to loose their primary teeth. Care of primary teeth is necessary because they can. Childhood tooth decay remains common in low ses effect baby teeth. children. Neural fibers in the brain continue to form synapses and mylenite. The cerebral cortex has overproduced synapses and synaptic pruning occurs. To make room for the connective structures of stimulate neurons, many surrounding neurons die, leading to reduced brain activity. Prefrontal cortical areas, involved in executive function show rapid growth. The left hemispheres develops before the right, supporting rapidly expanding language skill. Hand preference reflects the individual"s dominant cerebral hemisphere. Fibers linking the cerebellum to the cerebral cortex grow and myelinate, enhancing motor coordination and cognition. The reticular formation is responsible for alertness and. The hippocampus plays a vital role in memory and consciousness. understanding of space. emotional information.
