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"}],"ec_funded":1,"pubrep_id":"421","_id":"2031","oa_version":"Submitted Version","status":"public","date_published":"2014-12-09T00:00:00Z","type":"journal_article","volume":3,"project":[{"_id":"25C26B1E-B435-11E9-9278-68D0E5697425","name":"Mechanisms of transmitter release at GABAergic synapses","call_identifier":"FWF","grant_number":"P24909-B24"},{"grant_number":"268548","call_identifier":"FP7","_id":"25C0F108-B435-11E9-9278-68D0E5697425","name":"Nanophysiology of fast-spiking, parvalbumin-expressing GABAergic interneurons"}],"citation":{"mla":"Arai, itaru, and Peter M.
