Abstract: Role of serotonin in olfactory recognition was tested by depleting the olfactory bulb serotonin during postnatal day (PND)1- 4 following administration of 5,7-dihydroxytryptamine. Significant difference in the olfactory recognition test was observed during PND5-7; control pups successfully recognized and oriented towards their mother; whereas treated pups failed to recognize their mother odour. Later on, during PND12-14, both group of pups responded equally in the recognition test. Levels of olfactory bulb serotonin were depleted (53.3%) in the treated pups on PND-8, which was restored on PND-14 with only 15% variation. Further analysis demonstrated that depletion of serotonin in olfactory bulb did not affect the normal suckling and weight gain, it only modulates olfactory recognition.
