Paternal behavior is associated with central neurohormone receptor binding patterns in meadow voles (Microtus pennsylvanicus).

摘要: Paternal and nonpaternal voles (microtus) have different arginine-vasopressin (AVP) oxytocin (OT) receptor patterns in the extended amygdala, a neural pathway associated with parental behavior, Using autoradiography, authors examined whether AVP OT were facultative paternal behavior either sexually parentally inexperienced or experienced meadow (Microtus pennsylvanicus). Experienced, contrast to intexperienced, males had less binding lateral septum (LS), more anterior olfactory nucleus (AON), AON, bed of stria terminalis, LS, amygdala. Thus, specific patterns, which co-occur care consistently vales also may he (when present) typically species. This study demonstrated possible relationship between state male mammals.
