Non-negative Matrix Factorization as a Tool to Distinguish Between Synaptic Vesicles in Different Functional States

Authors Neher E, Taschenberger H Journal Neuroscience Citation Neuroscience. 2021 Mar 15;458:182-202. Abstract Synaptic vesicles (SVs) undergo multiple steps of functional maturation (priming) before being fusion competent. We present an analysis technique, which decomposes the time course of quantal release during repetitive stimulation as a sum of contributions of SVs,

The vesicle cluster as a major organizer of synaptic composition in the short-term and long-term

Authors Reshetniak S, Rizzoli SO Journal Current Opinion in Cell Biology Citation Curr Opin Cell Biol. 2021 Mar 8;71:63-68. Abstract For decades, the synaptic vesicle cluster has been thought of as a storage space for synaptic vesicles, whose obvious function is to provide vesicles for the depolarization-induced release of neurotransmitters;
