Questions and Answers

What was the outcome of artificially over-expressing the V1aR gene in the ventral pallium of male meadow voles?

  • Decreased number of Vasopressin 1A receptors on the post-synaptic membranes
  • Had no effect on the number of Vasopressin 1A receptors on the post-synaptic membranes
  • Altered the location of Vasopressin 1A receptors
  • Increased number of Vasopressin 1A receptors on the post-synaptic membranes (correct)

    • What effect did the increased V1aR gene expression have on the vasopressin-responsive neurons?

  • Reduced the effect of vasopressin released on the neurons
  • Caused the neurons to become less responsive to vasopressin
  • Had no impact on the vasopressin-responsive neurons
  • Enhanced the effect of vasopressin released on the neurons (correct)

    • What behavior did male meadow voles with V1aR Ventral Pallium over-expression exhibit that was non-species typical?

  • Strong huddling (correct)
  • Aggressive behavior
  • Increased solitary behavior
  • Avoidance of other voles
