[Facilitation phenomenon in the accessory and main olfactory bulbs of the frog Rana temporaria].
It has been demonstrated that facilitation of orthodromic EP by paired electrical stimuli (which was observed earlier in the accessory olfactory bulb of the frog) is also realized in the main olfactory bulb. Facilitation phenomenon in both bulbs is revealed provided the conditioned EP is present before paired stimulation. The accessory olfactory bulb differs from the main one by a longer duration of facilitation. Possible nature of facilitation phenomenon is discussed. It is suggested that differentiation of the olfactory system into the main and accessory ones may be based on differences in the velocity of their activity.
