Abstract
This paper addresses the issue of how efficient stimulus encoding may be ca rried out within the early stages of the olfactory system-in particular how a rate-coding scheme compares to the direct transmission of graded potenti als in terms of the accuracy of the estimate that an ideal observer may mak e about the stimulus. We make use of a spiking neuronal model of the early stages of the olfactory system that is driven by fluorescent microbead chem osensors in order to compare these two coding schemes. Our results indicate how the charging time-constants present at the first stages of neuronal in formation processing within the olfactory bulb directly affects its ability to accurately reconstruct the stimulus.
