Here, we examine the time course of release at inhibitory basket cell-Purkinje cell synapses and show that it is independent of [Ca2+]o. Modeling of Ca2+-dependent transmitter release suggests that the invariant time course of release critically depends on tight coupling between Ca2+ channels and release sensors. Experiments with exogenous Ca2+ chelators reveal that channel-sensor coupling at basket cell-Purkinje cell synapses is very tight, with a mean distance of 10–20 nm. Thus, tight channel-sensor coupling provides a mechanistic explanation for the apparent [Ca2+]o independence of the time course of release.","lang":"eng"}],"scopus_import":1,"intvolume":"         3","author":[{"full_name":"Arai, Itaru","id":"32A73F6C-F248-11E8-B48F-1D18A9856A87","last_name":"Arai","first_name":"Itaru"},{"full_name":"Jonas, Peter M","id":"353C1B58-F248-11E8-B48F-1D18A9856A87","last_name":"Jonas","orcid":"0000-0001-5001-4804","first_name":"Peter M"}],"date_created":"2018-12-11T11:55:19Z","pubrep_id":"421","title":"Nanodomain coupling explains Ca^2+ independence of transmitter release time course at a fast central synapse","day":"09","citation":{"mla":"Arai, itaru, and Peter M.
