A wide range of light-activated molecules (photoswitches and phototriggers) have been used to the study of computational properties of an isolated neuron by acting pre and postsynaptically. However. new tools are being pursued to elicit a presynaptic calcium influx that triggers the release of neurotransmitters. most of them based in calcium-permeable Channelrhodopsin-2 mutants. https://www.hindirochakkahaniya.com/
