BLUE: UNIT 3 Neural Mechanism
RED: UNIT 4 Neurons & Hormones
EXPERIMENT NAME HYPOTHESIS CONTROLS (+ other STRENGTHS LIMITATIONS
conditions)
Receptor for Monogamous higher expression Correlational study
Vasopressin - vole in ventral pallidum VP vs
brain scan non-monogamous higher Environmental influences
expression in lateral septum LS could also influence
vasopressin levels
Enhanced Partner Increasing V1aR expression in Infused with AAV which Between subjects design Environmental influences
Preference by adult non-monogamous male expressed irrelevant gene could also influence
manipulating single meadow vole will increase the vasopressin levels
gene - voles interaction with old mates
(=monogamous behavior)
Hanuman Langur Dominate male of the group is Observational study
Monkeys replaced the new male will spend
much of the time trying to kill
infants of the group
