Glutamate is an excitatory fast-acting neurotransmitter that mediates inter-neuronal communication. Evoked and spontaneous release of neurotransmitters are proposed to have distinct roles and rely on divergent vesicle pools and receptors. Moreover, changes in extracellular [Ca2+] ([Ca2+]o) are shown to differentially affect the probability of release for each mechanism. Ca2+ entry via voltage-gated calcium channels (VGCCs) is responsible for evoked release however the same pathway does not contribute to spontaneous release. How does extracellular [Ca2+]o stimulate spontaneous release? 000008410 536__ $$oU.S. Department of Veterans Affairs$$cBX002547 000008410 540__ $$fCC BY 000008410 542__ $$fIn copyright - joint owners 000008410 650__ $$aReceptors, Calcium-Sensing$$035430 000008410 650__ $$aCalcium$$015963 000008410 6531_ $$aPLC 000008410 6531_ $$aMEPSC 000008410 6531_ $$aneurotransmitters 000008410 6531_ $$aspontaneous release 000008410 7001_ $$aFeldthouse, Maya$$uPortland VA Medical Center$$041358 000008410 7001_ $$aSmith, Stephen$$uPortland VA Medical Center$$041358 000008410 711__ $$aResearch Week$$uOregon Health and Science University$$d2020 000008410 8564_ $$9cc659b94-3afc-45d1-bcf2-b4c516f78f90$$s43442$$uhttps://digitalcollections.ohsu.edu/record/8410/files/ResearchWeek.2020.Feldthouse.Mary.pdf 000008410 905__ $$a/rest/prod/k9/30/bx/55/k930bx55d 000008410 980__ $$aResearch Week
