Abstract	:	The sustaining fiber (SF) stage of the crayfish visual system converts analog stimulus repre-sentations to spike train signals. A recent theory quantifies a system's information processing ca-pabilities and relates to statistical signal processing. To analyze SF responses to light stimuli, weextend a wavelet-based algorithm for separating analog input signals and spike output waveformsin composite intracellular recordings. We also present a time-varying RC circuit model to capturenonstationary membrane noise spectral characteristics. In our SF anlysis, information transfer ra-tios are generally on the order of lo-". The SF information processing dynamics show transientpeaks followed by decay to steady-state values. A simple theoretical spike generator is analyzedanalytically and shows general dynamic and steady-state properties similar to SFs. The infonna-tion tnnsfer ratios increase with spike rate and dynamic properties are due to direct spike generatordependence on input changes..-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
