Abstract

We are interested in understanding how information about air-current dynamics is represented and processed in the primary sensory interneurons of the cricket cercal system. In this work, we develop channel models based on voltage-clamp data from Kloppenburg and Hörner (J. Exp. Biol. 201 (1998) 2529), use channel ensembles to construct model neurons, and analyze the underlying mathematical structure of these excitable systems. We also examine the behavior of the model neurons in response to constant frequency stimuli and its dependence on channel kinetics. This study provides a crucial step toward developing models for studying the contributions of channel dynamics to mechanisms underlying information processing in this system.
