Graded and prolonged presynaptic depolarizations trigger the tonic release of neurotransmitters from sensory neurons. In this issue of Neuron, Simmons reports that postsynaptic responses of locust interneuron synpapses are determined by the rate rather than the amplitude of presynaptic depolarization, suggesting a mechanism for increasing the signaling capabilities of this synapse with respect to visual processing.
