To explore the maximal rate of neuronal signaling and to analyze the presynaptic mechanisms, we focused on the input layer of the cerebellar cortex, where exceptionally high action potential (AP) frequencies have been reported invivo. With paired recordings between presynaptic cerebellar mossy fiber boutons and postsynaptic granule cells, we demonstrate reliable neurotransmission upto ~1 kHz. Presynaptic APs are ultrafast, with ~100μs half-duration. Both Kv1 and Kv3 potassium channels mediate the fast repolarization, rapidly inactivating sodium channels ensure metabolic efficiency, and little AP broadening occurs during bursts of up to 1.5 kHz. Presynaptic Cav2.1 (P/Q-type) calcium channels open efficiently during ultrafast APs. Furthermore, a subset of synaptic vesicles is tightly coupled to Ca2+ channels, and vesicles are rapidly recruited to the release site. These data reveal mechanisms of presynaptic AP generation and transmitter release underlying neuronal kHz signaling.","lang":"eng"}],"_id":"1898","publication":"Neuron","intvolume":"        84","citation":{"mla":"Ritzau Jost, Andreas, et al. “Ultrafast Action Potentials Mediate Kilohertz Signaling at a Central Synapse.” <i>Neuron</i>, vol. 84, no. 1, Elsevier, 2014, pp. 152–63, doi:<a href=\"https://doi.org/10.1016/j.neuron.2014.08.036\">10.1016/j.neuron.2014.08.036</a>.","apa":"Ritzau Jost, A., Delvendahl, I., Rings, A., Byczkowicz, N., Harada, H., Shigemoto, R., … Hallermann, S.
