| Research Abstract |
Neuronal populations essential for nipple search, nipple attachment and subsequent suckling behavior were determined to be approximately 50% and 40% of normal values of olfactory receptor neurons and bulbar projection neurons in neonatal rats. Further, suckling-related olfactory information was demonstrated to be conveyed via the lateral olfactory tract and its functional recovery was determined to occur approximately 2 weeks after the tract transection of neonatal rats.
