A red-emitting, genetically encoded indicator for two-photon voltage recording in vivo www.biorxiv.org/content/10.6...
Excited to announce big steps for electrical imaging in the brain! In 4 preprints, we and collaborators present 2 new GFP-based voltage sensors: ASAP6c for high-throughput spike recordings, and ASAP7y for subthreshold 1P and 2P imaging bit.ly/4x3k3kX bit.ly/3RKZhq3 bit.ly/4o4fKl3 bit.ly/4uHXuk3 🧵
Neuropixels + Optogenetics = Neuropixels Opto Combining high-resolution electrophysiology and optogenetics. 960 sites, 28 emitters, 2 colors. Today in @natmethods.nature.com doi.org/10.1038/s415... Thanks to @wellcometrust.bsky.social, @alleninstitute.org, @hhmijanelia.bsky.social & team.
