Reproductively experienced male California mice (Peromyscus californicus) act highly paternal towards their own as well as non-related pups. I am trying to answer several research questions:

-is behavior towards a non-related pup different between virgin, sexually experienced (pair-bonded) and paternally experienced male California mice, and if so: why and how?
-which brain areas (medial preoptic area, nucleus accumbens, medial/central amygdala, ventromedial hypothalamus, bed nucleus of the stria terminalis) and neuropeptides (oxytocin, vasopressin, CRH, prolactin) are involved in (the transition to) paternal behavior?

General Research Interests

I am broadly interested in the neuroanatomical organization of behavior. Which central nervous system pathways and neurotransmitters control complex behavioral patterns such as copulation, parental behavior and coping with stress and anxiety? I have studied these topics using mice, rats and guinea pigs and am now working with the lovely California mice.
