Compared with humans, however, prairie voleshave whirlwind courtships.
Within a day, a pair of the rodents can form a bond that lasts a lifetime.
The findings also reveal a surprising connection between orgasms andneural activity.
Then, the voles brains were prepared for neuroimaging.
This suggests ejaculation during mating plays an essential part in activating the neural circuits involved in bond formation.
Interestingly, both males and females responded to this effect.
Females also exhibited increased bonding-related brain activity when paired with males who reached this milestone.
