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...

We identified how mechanical forces shape myelin development. The TMEM63A channel in oligodendrocytes converts physical cues into molecular signals that control myelin growth. Oligodendrocyte mechanotransduction channel TMEM63A regulates myelin sheath geometry: Neuron www.cell.com/neuron/fullt...

We are delighted to sponsor both the GRC and GRS meetings, supporting innovative science and the next generation of leaders in basal ganglia research. #CoherentCorp #GRCBasalGanglia

❄️ Now I understand why people rave about Winter Conferences. I attended one last week and am still under the influence of the fantastic conversations, presentations, and mountain views. #neuroscience

On my way to BIOS and Photonics West in San Francisco. There will be many interesting presentations from Coherent (see the list under link below). Pick and choose something to match your interests! See you soon! #BIOS26 #PW26 www.coherent.com/events/photo...

🔬 What’s next for ultrafast laser sources in multiphoton microscopy? Let's meet at BIOS on January 18, 2026 | 3:25 PM - 3:40 PM PST | Room 160 (Moscone South, Upper Mezzanine) and discuss! #BIOS26 #PhotonicsWest #UltrafastLasers #Microscopy #Photonics @spie.org spie.org/photonics-we...

#fluorescencefriday shows the intimate relationship between astrocytes, (cyan) microglia (green) and amyloid plaques (magenta). we find that in APOE4 mice there is much more glia associated with plaques.

Exploring the Brain - One Spine at a Time 🔬 Just chatted with @sainsburywellcome.bsky.social about our latest work, miniaturising two-photon microscopy for neuroscience at @kavlintnu.bsky.social www.sainsburywellcome.org/web/qa/mini-... A few highlights:

Good morning from Maine! #conference

Very nice nature review on emerging three-photon microscopy!

Going East, again this summer.

Beautiful Saturday

Absolutely gorgeous both shape and color palette

A nice z-stack through cortical layers containing plaques and structures that express vimentin, a cytoskeletal protein. #microscopy #neuroscience #2Photon #fluorescence

We're having a great time at @mblscience.bsky.social Neurobiology, and @nsb-mbl.bsky.social courses! This time excited to showcase multiphoton microscope from Sutter, powered by the Chameleon Discovery LX femtosecond laser from Coherent Corp. #microscopy #neuroscience #2Photon #STEM

Proud to support the next generation of imaging scientists. Here are a few shots of Coherent's ultrafast fixed-wavelength Axon lasers at 780, 920, and 1064 nm, lighting Thorlabs scope-ready for student prepared samples at @mblscience.bsky.social. #Microscopy #Neuroscience #UltrafastLasers #STEM

I told you 🫵

It's officially published!! In my main postdoc work with @markplitt.bsky.social and @lgiocomo.bsky.social, we found that the hippocampus simultaneously encodes an animal's spatial position and its experience relative to reward in parallel population codes. 🧵 www.nature.com/articles/s41...

Hey! I’ll be in the Boston area next week and at MBL consulting on imaging technologies. If you're using multiphoton microscopy in your research, I'd love to hear about your applications and share some of the latest laser developments from Coherent. Send me a msg.

Loved the @neurophotonics.bsky.social summer school, Quebec City and French people. Also got in touch with some people I’ve been meaning to connect with for a while!!

On the plane next to a guy with a running nose. It hurts my ears. Offered a tissue to him but he refused and warned me to continue making the noise.

Here come our new palette of fluorescent dyes. The BD dyes endeaves to balance glowy brightness, robust photostability, and biocompatibility. Let's boost 4D dynamic super-resolution imaging!!! www.nature.com/articles/s41... @spirochrome.com

I'm looking forward to attending, even if just briefly, the 18th Edition of the Frontiers in @neurophotonics.bsky.social Summer School this week at the CERVO Brain Research Center in Quebec City. I have a few openings on Wednesday (June 4). Let me know if you'd like to catch up or show me around!

It is out! Read how you achieve 1.7 mm deep 3-photon imaging in prefrontal cortex with dendritic spine resolution over a week. www.nature.com/articles/s42...

I urge everyone to read Unbreaking’s new page on everything the govt is doing to destroy & diminish medical research funding. It’s the best thing I’ve read on this topic: @lizneeley.bsky.social & co have such done an incredible job. unbreaking.org/issues/medic...
