Dynamically primed synaptic vesicle states: key to understand synaptic short-term plasticity

E Neher, N Brose - Neuron, 2018 - cell.com
Based on evidence that the docked and primed synaptic vesicle state is very dynamic, we
propose a three-step process for the buildup of the molecular machinery that mediates …

Single bursts of individual granule cells functionally rearrange feedforward inhibition

M Neubrandt, VJ Oláh, J Brunner… - Journal of …, 2018 - Soc Neuroscience
The sparse single-spike activity of dentate gyrus granule cells (DG GCs) is punctuated by
occasional brief bursts of 3–7 action potentials. It is well-known that such presynaptic bursts …

GPCR regulation of secretion

YY Yim, Z Zurawski, H Hamm - Pharmacology & therapeutics, 2018 - Elsevier
Modulation of neurotransmitter exocytosis by activated G i/o coupled G-protein coupled
