Many neurones in the Aplysia abdominal ganglion are active during the gill-withdrawal reflex

摘要: Publisher Summary This chapter describes the results of application optical methods for monitoring neuron activity to abdominal ganglion Aplysia. The recording are used study interneurons in Aplysia during gill-withdrawal reflex. technique is based on a system changes absorption or fluorescence voltage-sensitive dye that has stained piece nervous tissue. In recordings from intact invertebrate ganglia, signal-to-noise ratio been larger than californica. illustrates analysis 124 detectors two gill withdrawals one preparation. this study, number active neurons was 150 sensitized state and 92 habituated state. action potential siphon, brachial, genital nerves pleuro-abdominal connectives recorded with extracellular electrodes. also comparison spikes per second. main effect habituation sensitization neurons, although there appears be small cell.
