PSY E111 Chapter Notes - Chapter 1: Pituitary Gland, Language Development, Sensory Cortex
Document Summary
Hypothalamus = body temperature, food intake, thirst, behavior. Thyroid = metabolism, parathyroid = calcium, adrenal = fight or flight, pancreas = sugar, testes = male sex, ovary = female sex. Androgens = male sex hormones (testosterone), estrogens = female sex hormones (estradiol), also progestins (progesterone) Presence or absence of testosterone determines genital development. Turner = xo, klinefelter = xxy, cah = extra androgens, ais = xy with defective androgen receptors. Sexual dimorphisms: men larger cerebral cortexes, sdns, amygdala (fight or flight); women larger frontal and limbic cortex parts (cognitive function, emotion), proportion of corpus callosum. Once excited, neurotransmitters cross synapse from axon to dendrite. Brain stem: includes medulla and pons life sustaining functions: midbrain/thalamus: relay and process sensory information, perform early regulatory functions, cerebellum: movement and sensory integration. Limbic system: emotion, motivation, learning, memory: hypothalamus: drinking, eating, sex, reward center, amygdala: emotion, evaluating stimuli, hippocampus: learning, forming new memories. Social referencing (7-9 months) = reliance on facial cues.
