Early appearance of inhibition in the neonatal rat olfactory bulb.
The functional development of inhibition in the rat olfactory bulb was examined in the present study. Inhibition of presumed mitral cell spontaneous activity following stimulation of the lateral olfactory tract was present by postnatal day 5, the youngest age tested. The duration of this inhibition was greatest in young animals, decreasing after postnatal day 15. Possible mechanisms of this enhanced inhibition in neonates were discussed.
