Behavioral Alterations in Prairie Voles (Microtus ochrogaster) after Parent-Pup SeparationYamamoto, Mihoko 01 January 2009 (has links) (PDF)
The prairie vole (Microtus ochrogaster), a highly social species, offers a unique opportunity to examine the effects of parent-pup separation in a biparental family system similar to humans. We hypothesized that 1) repeated separation from pups affects parental behavior and emotionality in parents, and 2) neonatal parental separation affects emotional and physiological development in pups, and thus induces altered adult parental, emotional, and social behaviors. During postnatal day (PND) 1-10, pups were removed from their parents for 0, 15, or 360 min and housed either individually or with siblings. Unhandled controls experienced only daily lid opening. Tests for parental responsiveness and emotionality were conducted on PND11 for parents and PND90-92 for their offspring. Emotionality tests included the elevated plus maze, open field, and forced swim tests. Starting at PND150, half of each litter was paired with an opposite-sex vole for 24 hours and tested for partner preference. Additionally, behavioral response to stress was measured in all animals 0, 30, or 60 min after exposure to a forced swim. Generally, the behavior of the parents and adult offspring was influenced by daily handling, the length of the separation, and presence of siblings. Parental behaviors in parents did not differ among groups, while their anxiety- and depression-like behaviors were influenced by pup separation. For the adult offspring, separation treatment altered parental behavior, emotionality, partner preference, and stress response. Our results demonstrated that parent-pup separation affects emotional and social behaviors in prairie vole parents and adult offspring.

Comparative Neuroanatomy of the Sexually Dimorphic Hypothalamus in Monogamous and Polygamous VolesShapiro, Lawrence E., Leonard, Christiana M., Sessions, Charlene E., Dewsbury, Donald A., Insel, Thomas R. 15 February 1991 (has links)
In the present work we evaluated the degree of sexual dimorphism in two cell groups of the medial preoptic-anterior hypothalamus (MPOA-AH) in monogamous and polygamous voles. Quantitative determinations were made of volume, cell number, and cell density for the anteroventral-periventriular nucleus (AVPV) and the sexually dimorphic nucleus of the preoptic area (SDN-POA). Polygamous montane voles (Microtus montanus) had a greater degree of sexual dimorphism in both cell groups than did monogamous prairie voles (M. ochrogaster). Most notable was the complete absence of the AVPV in male montane voles; male montane voles also had a significantly larger SDN-POA volume than did females. The only sexual dimorphism in prairie voles was a greater cell density in the female AVPV. In addition, prairie voles had larger relative brain size than did montane voles. Comparative behavioral studies have revealed a correlation between the degree of sexual dimorphism in external morphology and mating system, i.e., polygamous species display greater levels of dimorphism than do monogamous species. The present results indicate that the effects of sexual selection can also be seen in those brain regions, like the hypothalamus, that underlie social and reproductive behavior. Moreover, these results support the hypothesis that neuroanatomic dimorphisms in the MPOA-AH may be related to sex differences in behavior.
