Biological bases of behaviour: the brain, left/right side dominant brains is a myth. Creativity and logic in both halves: parts i. Hindbrain: vital functions: circulating blood, breathing, sleep, coordinated movement. Coordinate fine motor movement (1st affected by alcohol: midbrain, sensory functions: voluntary movement, pain perception. Important structures: voluntary movements, reticular activating system, sleep and arousal regulation iii. Forebrain (deep structures: human functions: emotion, complex thought. Relay station, sensory integrator: hypothalamus i. ii. Limbic system: hypothalamus 4 f"s, feeding, fleeing, fighting, reproduction, amygdala: perceive emotion and feat, hippocampus: new memories iii. Cerebrum: 2 hemispheres, left hemisphere - verbal processing: language, speech, reading, writing, right hemisphere - nonverbal processing - spatial, musical, visual recognition, 4 lobes, frontal - forehead i. Wernicke"s: parietal - above & behind temporal lobe i. Somatosensory, touch information: occipital - back of head i. Left hemisphere: language, mathematics, analytic, sequential: 95% of right handers, 62% of left handers, typically wired to right side of body ii.
