Normal homing behavior in infant rats despite extensive olfactory bulb granule cell losses

Abstract

Severe irradiation-produced granule cell losses in the internal granular layer of the main olfactory bulb had no significant effects on homing to home-cage wood shavings in infant rats on postnatal Days 9 and 13. Granule cells of the main olfactory bulb do not seem to be required for the mediation of this behavior.
