Description
This research was designed to assess the extent to which olfactory
cues, both main olfactory and vomeronasal, are important in the
expression of independent ingestion in 6-day-old rat pups.
Independent ingestion in young rat pups involves the intake of
large volumes of milk (delivered throught an intraoral cannula)
and is accompanied by dramatic behavioral activation. It was found
that behavioral activation in response to milk infusions or milk
odor was eliminated in pups deprived of main olfactory input (by
nasal lavage with ZnS04), or vomeronasal input (by vomeronasal
nerve sections). Similarly, after vomeronasal deafferentation and
ZnS04 lavage pups cease to probe and become active in response to
milk infusions and milk odor accompanied by water infusions. The
results suggest that behavioral activation may be mediated in a
similar fashion by both the main and vomeronasal olfactory system.
