Summary Single olfactory receptor cells of the migratory locust and of honeybee drones were stimulated with the two enantiomeric forms of 4-methylhexanoic acid. In the majority of cells, equal stimulus quantities of either the (+)- or the (−)-isomer elicited a greater number of nerve impulses. Behavioral discrimination of the two enantiomers was demonstrated in drones. Here, the proboscis extension response served as indicator of the discrimination following the conditioning to one or the other steric antipode. These findings are explained by a minimum of two variants of one structurally highly stabilized type of acceptor present in different numbers on the membranes of individual cells of this type.
