An implantable device based on organic electrochemical transistors is developed for quantitative mapping of neurotransmitter release across multiple brain regions, revealing a cross-talk between the mesolimbic and nigrostriatal dopaminergic pathways.
The crystal structure of a large C-terminal fragment of Munc13-1 provides a key framework to understand how Munc13-1 mediates neurotransmitter release and presynaptic plasticity.
Cryo-electron tomography, reconstitution, and electrophysiological data show that a fundamental function of Munc13-1 is to bridge synaptic vesicles to the presynaptic plasma membrane.
Naturally-occurring v-SNARE TMD variants differentially regulate fusion pore dynamics and cooperate with phospholipids in supporting membrane curvature at the fusion pore neck.
Challenging a widespread model, biophysical and electrophysiological experiments suggest a new mechanism whereby complexins inhibit neurotransmitter release through electrostatic repulsion between their accessory helix and the membranes.
Fluorescent glutamate indicators distort the time course of neurotransmitter diffusion and uptake by competing with transporters, an important caveat to consider when using iGluSnFR and its analogs.
Dopamine release within the mouse external globus pallidus, an area of very sparse innervation, is observed and described for the first time through a new technique: flashing false fluorescent neurotransmitters.
