The gastropyloric receptor (GPR) neurons of the stomatogastric nervous system of the crab Cancer borealis are muscle stretch receptors that can fire in either a spiking ora bursting mode of operation. Our goal is to understand what features of muscle stretch are encoded by these two modes of activity. To this end, we characterized the responses of the GPR neurons in both states to sustained and rapidly varying imposed stretches. The firing rates of spiking GPR neurons in response to rapidly varying stretches were directly related to stretch amplitude. For persistent stretches, spikingmode firing rates showed marked adaptation indicating a more complex relationship. Interspike intervals of action potentials fired by GPR neurons in the spiking mode were used to construct an accurate estimate of the time-dependent amplitude of stretches in the frequency range of the gastric mill rhythm (0.05–0.2 Hz) . Spike trains arising from faster stretches (similar to those of the pyloric rhythm) were decoded using a linear filter to construct an estimate of stretch amplitude. GPR neurons firing in the bursting mode were relatively unaffected by rapidly varying stretches. However, the burst rate was related to the amplitude of long, sustained stretches, and very slowly varying stretches could be reconstructed from burst intervals. In conclusion, the existence of spiking and bursting modes allows a single neuron to encode both rapidly and slowly varying stimuli and thus to report cycle-by-cycle muscle movements as well as average levels of muscle tension.  \nI N T R O D U C T I O N  \nSensory neurons use a variety of coding strategies to deal with the wide dynamic range of the stimuli to which they respond. Some sensory neurons respond phasically to a signal, that is, their firing rates are initially affected by rapid changes in the stimulus but subsequently adapt. Other sensory neurons show considerably less or no adaptation and encode sustained stimulus intensities. An advantage of sensory neurons that show adaptation is that they can report changes in stimulus intensity over a very large range, whereas neurons that do not have appreciable adaptation may only be able to report stimulus intensity over a more limited range of values. It is often assumed that information about changes in stimulus intensity and information about sustained stimuli are encoded by different neurons. In this paper we demonstrate that a single muscle stretch receptor neuron can encode information over two different time scales by firing in two modes, spiking and bursting.

The stomatogastric nervous system of C. borealis is a small, well-studied neural network that controls stomach movements (Harris-Warrick et al. 1992) . The 25–26 motor neurons (Kilman and Marder 1996) in the C. borealis stomatogastric ganglion (STG) can be divided roughly into two groups: those innervating the muscles that move thr","cbCaimpyRp7vWtWc","https://ap.wps.com/l/cbCaimpyRp7vWtWc","pdf",617177,12,"English","# Introduction\n## Coding strategies in sensory neurons\n## Gastropyloric receptor neurons and two-mode behavior\n# Methods\n## Animals and solutions\n## Physiology","[{\"question\":\"What question does the study address about muscle stretch encoding?\",\"answer\":\"It examines what features of muscle stretch are represented when a single GPR sensory neuron alternates between spiking and bursting modes.\"},{\"question\":\"How is stretch information encoded in the spiking mode?\",\"answer\":\"For rapidly varying stretches, spiking firing rates track stretch amplitude, while for sustained stretches spike trains require interval-based decoding to estimate time-dependent amplitude.\"},{\"question\":\"How is stretch information encoded in the bursting mode?\",\"answer\":\"Burst rate relates to the amplitude of long, sustained stretches, and very slowly varying stretches can be reconstructed from burst intervals.\"}]","Encoding of Muscle Movement on Two Time Scales by a Sensory Neuron That Switches Between Spiking and Bursting Modes | PDF"]
