The Inhibition of Infanticidal Behavior Requires

Question

The inhibition of infanticidal behavior requires:
A) the vomeronasal organ in males.
B) the TrpC2 channel in males.
C) galanin-expressing neurons of the medial preoptic area in parents.
D) galanin-expressing neurons of the medial preoptic area in virgin females.
E) All of the above

Accepted Answer

Vomeronasal organ-ablated and Trpc2 knockout male mice exhibit reduced infanticidal behaviors. Ablation of the galanin-expressing neurons of the medial preoptic area, which may be the target cells of the accessory olfactory system, increases pup attacking in virgin females but not in male or female parents.
