Exposure to an unrelated male or its urinary pheromone is essential to induce estrus in female voles. |
Male prairie voles become aggressive after mating and exhibit aggression towards intruders. |

Vasopressin in the Vole Brain |

Vasopressin immunoreactive fibers in the lateral septum of male prairie voles that were intact (A), castrated (B), or castrated and implanted with testosterone (C) |

Neurogenesis in the Vole Brain |
 |
|
Neurons and glia labeled for BrdU, a cell proliferation marker, in the rostral migratory stream of the adult prairie vole brain. |
 |
|
BrdU-labeled cells in the dentate gyrus of the hippocampus 48 hours after treatment. Subjects were female prairie voles either (A) isolated, (B) housed with a female, or (C) housed with a male. (GCL= granule cell layer; Hil= hilus) |

Confocal laser microscope images of cells stained for BrdU, TuJ1 and/or NG2 in the amygdala of male meadow voles. Images display staining for new cells [(A) BrdU, red], neurons [(B) TuJ1, green], glia [(C) NG2, blue], and all three markers (D). A new neuron (BrdU and TuJ1 colocalized) cells display a yellow image (arrow), and a BrdU only labeled cell displays a red image. |
Cells in the dentate gyrus of the hippocampus double-labeled for BrdU (red) and TuJ1 (green). |
