Unformatted text preview: Bales study questions for NPB 152: Final, Spring 2010 These questions are devised to help guide your studying. Not all of them will appear on the exam; and these may not include EVERYTHING that may be asked on the exam. We will not provide an answer key, but if you are unsure what we are asking, email myself ([email protected]) or Michael Jarcho ([email protected]) or come to office hours. Affiliation and Aggression 1. Oxytocin and vasopressin are made in which nuclei in the hypothalamus? They are made in the paraventricular and supraoptic nuclei. 2. Which type of neurons are “large” cells that make the OT and AVP which gets released into the periphery via the posterior pituitary? Magnocelluar neurons are large cells that make the OT and AVP which gets released into the periphery via the posterior pituitary. 3. Which type of neurons are “small” cells that make the OT and AVP released into the rest of the brain? Parvocelluar neurons are small cells that make the OT and AVP released into the rest of the brain. 4. V1a receptors are higher in monogamous voles than in polygynous voles, primarily in which brain area? Monogamous voles have high densities of V1a receptors in the ventral pallidum. 5. OT receptors are higher in monogamous voles than in polygynous voles, primarily in which brain area? Monogamous voles have high densities of OT receptors in the nucleus accumbens. 6. Which vole species are monogamous and which are polygynous? M onogamous: P rairie and P ine P olygamous: M eadow and Mountain 7. Manipulation of V1a receptor levels in mice by injection of prairie vole receptor genes had what effect on social behavior? Mice got more social but they still didn’t form a pair bond. 8. Manipulation of V1a receptor levels in meadow voles by injection of prairie vole receptor genes had what effect on pair-bonding? You get partner preference in the meadow voles. 9. What happens to pair-bonding behavior if you: a. block OT receptors in a female – Block PB. b. block AVP receptors in a female – Block PB. c. block D2 receptors in a female – Block PB. d. block D1 receptors in a female – No change. e. block OT receptors in a male – You lose it. f. block AVP receptors in a male – You lose it. g. block D2 receptors in a male – Block PB. h. block D1 receptors in a male – No change. i. increase CRH in a male – Shorter time to PB. j. increase corticosterone in a female – Take longer to PB . k. increase corticosterone in a male – Shorter time to PB. l. adrenalectomize a male – Longer time to PB. m. adrenalectomize a female – Shorter time to PB. 10. Name the brain areas involved in pair-bonding behavior. What is the most crucial area for each sex? Why are these considered the most crucial area?...
