Abstract

Precise measurement of receptor thresholds is important in understanding the role a sense organ plays in the biology and the sensory information processing of an organism. Previous crustacean chemoreceptor thresholds are too high because of the adaping effects of high stimulus intensities and the order effects of stimulus presentation sequence used in threshold experiments now in the literature. The present study uses an experimental design geared to produce the lowest adaptation possible and shows that single unit chemoreceptor activity occurs at lower concentrations than any previously documented. The differences between lateral and medial chemoreceptor and the variability of the antennular chemoreceptor population are also treated in the present study. It is concluded that threshold differences do not account for the differential behavioral effect of lateral vs medial antennal filament ablation, and that the observed response variability is inherent in receptor response and important to receptor function.
