Document Summary
Structure ad connections of the hypothalamus: each side of hypothalamus: 3 functional zones, lateral, medial and periventricular. Increases brain responsiveness, speeding info by point to point sensory and motor systems: breakthrough: hillarp and falck, axons leave the locus coeruleus in many tracts and innervate cerebral cortex, thalamus, hypothalamus, olfactory bulb, cerebellum, midbrain and spinal cord. 4 tflow of sympathetic and parasympathetic innervation of visceral organs: neurosecratory neurons: extend axons down toward the stalk of pituitary gland, command attention. Pathways to the pituitary: has two lobes: posterior and anterior, hypothalamus controls both differently. Increases brain responsiveness, speeding info by sensory and motor systems: breakthrough: hillarp and falck, axons leave the locus coeruleus in many tracts and innervate cerebral cortex, thalamus, hypothalamus, olfactory bulb, cerebellum, midbrain and spinal cord. 5: raphe nuclei cells fire most during wakefulness (aroused and active, most quiet during sleep. Locus coeruleus and raphe nuclei are part of ascending reticular activating system.
