Pharmacological study of the one spike spherical neuron phenotype in Gymnotus omarorum

Highlights • Gymnotus shows one-spike neurons firing one-to-one after electric organ discharge. • A low-threshold potassium channel supports such a profile, causing long refractoriness. • These features subserve a dynamic sensory filter for streaming self-generated signals. • Differences with wave f...
