WebDec 22, 2014 · We have developed an all-optical strategy for activating and recording the same neurons with cellular resolution in mice in vivo using a dual two-photon optogenetic and calcium imaging approach. The strategy relies on viral coexpression of a genetically encoded activity sensor (GCaMP6s) and a red-shifted opsin (C1V1). WebDuring my PhD and internship, I focused on VIS-NIR open-optic spectroscopic setup to record the optical response of my sensing chip in contact with biological samples (e.g. cell and tissue) as well as microscopy-based measurements to reveal their neural activity under electrical, chemical or optical stimulations. Besides my main project, I was working on …
