Here’s our latest preprint on uncovering neural control of a coordinated walking pattern! doi.org/10.64898/202... (author-list jumbled, see pdf for corrected). Video shows the central paradigm in this study, we optogenetically induce walking in headless flies and sequentially reduce proprioception.

Back from #OpticaBiophotonics26. I had an opportunity to share how we think about lasers and our laser solutions for emerging imaging applications.

PinkyCaMP is finally published!! My first paper co-first authored with @sikmys.bsky.social where we make a great optogenetic and multiplex compatible red calcium indicator. Thank you to @massecklab.bsky.social and @campbell-lab.bsky.social for guiding this journey www.nature.com/articles/s41...

Open-source modular FPGA system for two-photon mesoscope: multiarea, multidepth neural activity recording. @riichirohira.bsky.social et al. present high throughput 2p calcium and what is maybe the largest field-of-view 2p fluorescence lifetime imaging (FLIM) data. doi.org/10.1117/1.NP...

I spent a bit more time thinking about this pre-print biorxiv.org/content/10.6... 👉3P isn't about more laser power. It's about the right rep rate, one pulse per pixel, and laser stability. If you are not measuring pulse-to-pulse noise you're not measuring your biology.

Back from #FOM2026. In multiphoton microscopy space label-free imaging, and spectroscopy in structural and metabolism biological imaging stood out. I’m excited to grow and support this space too.

*First preprint from our lab* !!!!! How does the brain learn to anchor its internal sense of direction to the outside world? 🧭 led by Mark Plitt @markplitt.bsky.social & Dan Turner-Evans, w/ Vivek Jayaraman: “Octopamine instructs head direction plasticity” www.biorxiv.org/content/10.6... Thread ⬇️

The most sensitive green and red #norepinephrine #sensors engineered to date are out in #naturemethods! Deeply grateful to all our funders and contributors who made this work possible. A true team effort. @erc.europa.eu @snsf.ch doi.org/10.1038/s415...

We are finally online 🥳 What a fantastic adventure with @rrsims, the @emilianilab.bsky.social and all co-authors from IdV Paris #TwoPhoton #Voltagers #Holography #Rhodopsins

😎I'm delighted to announce that Coherent Corp. will be exhibiting at Sunposium Conference (mpfi.org/events/sunpo...) on Mar 09 - 11, 2026 in West Palm Beach. 🤩Attend my presentation Monday, March 10, board #101. 🤝Schedule a 1-1 with me to talk about your next microscopy projects. #neuroscience

Out today in Neurophotonics, we show that cross-talk between the imaging laser and opsin in all-optical experiments can affect response dynamics beyond what has been accounted for. Imaging conditions subthreshold for evoking spikes can accelerate opsin desensitization: doi.org/10.1117/1.NP...
