Sensory coding taking place at the level of receptor cells, and the adjacent neuronal circuitry is a conditio sine qua non for processing of olfactory stimuli. However, those sensory events do not represent the whole coding process. Different features concerning the stimuli in question are being ascribed to the corresponding neural message processed by the brain, probably. The added parts of the code are derived from two sources, apparently: from information concerning the proper stimulus, and those generated from interactions between the stimulus and the brain. The results discucced in the present paper have been acquired in psychophysical experiments. The aim was to draw inferences on the underlying coding processes. Candidates for feature codes could be considered: the presence/absence of the stimulus, its quality, intensity, spatial localization, dicriminability from other stimuli, mutual timing with respect to other stimuli, adherence to a stimulus sequence of increasing intensity. Interaction coding concerns: the conscious nature of the stimulus, its hedonic interpretation, the signalling features added by Pavlovian conditioning, and its dependence of the actual state of the brain.
