Document Summary
Serotonin normally involved in regulating high levels of carbon dioxide buildup in blood, and expel gas. Causes serotonin to be less effective during life threatening events (such as carbon dioxide buildup during sleep) that is trapped in bedding and suffocate: higher sid mortality in boys. Have fewer 5-ht1a receptors (reduce serotonergic system"s effectiveness in regulating behavior) Increased connections between neurons (not increased numbers: as brain develops + forms complex behavior. Structural development of nervous system can be correlated with emergence of specific behaviors. Development of brain structure to motor development (grasping, crawling) Neural structures that develop quickly visual system exhibit functions sooner than structures that develop slowly, such as speech. Cognitive behaviors in frontal lobes develop last. Tower of haoni test shows how planning skills can be measured in laboratory. Changes associated with neural structures when language emerges in young child. Interrelations between brain and behavior development is to identify factors that influence both.
