NEURAL MECHANISMS IN THE ANTERIOR OLFACTORY NUCLEUS OF THE RABBIT AND THEIR POSSIBLE RELEVANCE TO LOCALIZATION OF AN OLFACTORY SOURCE

Extracellular recordings were obtained from 40 Anterior Olfactory Nucleus (A.O.N.) units in response to birhinal olfactory stimulations. The units located in the A.O.N. pars dorsalis responded differently according to the time interval between the onsets of right and left puffs during birhinal olfactory stimulation. On the contrary, the greater part of the units located in the A.O.N. pars ventralis was not sensitive to time intervals variations. These data indicate the ability of some A.O.N. cells to encode temporal characteristics of an olfactory stimulation. © 1979 Information Retrieval Ltd, 1 Falconberg Court, London WIV 5FG, England.
