Neurobiological Bases of Paternal Nurturance
Biological Bases of Individual Variation in Paternal Nurturance
The overall goal of this project is to identify the genetic, hormonal, and neurobiological influences on paternal nurturing behavior and to determine if fathers' neural responses to infants can be modulated by neuropeptides known to play a role in parenting in experimental animal models.
The aim is to determine if pharmacological manipulation of central oxytocin (OT) and vasopressin (AVP) levels influences the neural response to viewing pictures of one's own infant or to hearing cry stimuli. In a double-blind procedure, fathers with 1-3 year old children will be scanned on two separate occasions; once under the influence of OT/AVP and once under the influence of placebo. Fathers will be randomized to either OT or AVP, and order of administration of drug and placebo will counterbalanced across subjects. Fathers will be scanned while viewing pictures of their own and an unknown child and while listening to unknown infant cry stimuli.
The investigators hypothesize:
- OT will augment the ventral tegmental area (VTA), ventral striatum and medial orbitofrontal cortex (mOFC) response to viewing pictures of one's own child, and will augment the primary auditory cortex (AI) response of fathers to infant cries.
- AVP will augment the lateral septum response to viewing own child pictures.

Inclusion Criteria:
- above 18
- biological fathers of 1-3 year old infants who are currently cohabitating with the child's mother
- normal or corrected-to-normal vision of 20/40
Exclusion Criteria:
- current or past history of mental illness
- active medical or neurological disorder
- current or past history of alcohol or drug dependence
- claustrophobic (at the discretion of the PI with subject consultation)
- history of seizures or other neurological disorder
- history of hypertension, cardiovascular disease, nephritis, diabetes or other endocrine diseases or malignancy

Kokeellinen: OT + placebo
The OT + placebo group will self-administer no more than 1 ml solution of oxytocin or placebo in each nostril; five (5) sprays per each nostril, for a total of ten (10) sprays.
The order of administration of drug and placebo will counterbalanced across subjects, such that half will receive OT first, and half will receive OT second.
