Menzinger M., Rovinsky A., Chillemi S. Dynamics of analog-to-frequency transduction in sensory receptors. In: Biosystems, vol. 40 (1-2) pp. 119 - 126. Elsevier, 1997.
We analyze the analog-to-frequency transduction by sensory neurons in vivo. Spatially extended neural models are made to fire by applying the stimulus to the membrane potential at the boundary of the trigger zone. The membrane property that provides a broad dynamical range of frequency is a prolonged hyperpolarizing afterpotential. In support of this PDE model, we study the stimulus-dependent location of pulse-initiation in crayfish stretch receptors Ringham (1971).
