Differential odor processing in two olfactory pathways in the honeybee.

摘要: An important component in understanding central olfactory processing and coding the insect brain relates to characterization of functional divisions between morphologically distinct types projection neurons (PN). Using calcium imaging, we investigated how identity, concentration mixtures odors are represented axon terminals (boutons) two PNs - lPN mPN. In boutons found less dependence, narrow tuning profiles at a high concentration, which may be optimized for fine, concentration-invariant odor discrimination. mPN boutons, however, clear rising broader coding. addition, more mixture suppression lPNs than mPNs, indicating better adaptation synthetic processing. These results suggest division both PN types.
