It seems like magic!

Also works for increasing the phase range of adaptive optics!

Check out this video if you want to be walked through the preprint. https://t.co/fhcINT84kP

[Spencer LaVere Smith @Labrigger]

NEW PREPRINT: For 2-photon imaging (or any laser scanning), fast scanning often shrinks the field-of-view and/or decreases resolution.

Che-Hang Yu found a bunch of ways to increase the field-of-view, with no trade-offs in speed or resolution. 1/2

@brunopichler @pacificoptica Thanks, Bruno! And if anyone wants to learn more about the optics, they might have fun with this video: https://t.co/fhcINT84kP

[Bruno Pichler @brunopichler]

Fantastic work (as always) from Che-Hang Yu and colleagues in Spencer Smith's lab @Labrigger. Neat method to increase scan speed and/or FOV in 2p microscopy. Commercially available from @pacificoptica . I'd love to build this for a client at some point! https://t.co/caj5Pv3ZIA

Beautifull! Nisam + Cousa (>3 mm x > 3mm) by Che-Hang Yu et al.

[Spencer LaVere Smith @Labrigger]

This is actually fun. Try it!

Your preprint -> AI-generated fake podcast -> video with actual human commentary -- It's remarkably effective!

I wrote to my representatives again. Maybe at this point I should just let them subscribe to my newsletter.

Huge field of view with a scan engine https://t.co/v0RUDxXOlT

[Pacific Optica @pacificoptica]

The Ventana SL and Ventana TL are now available. https://t.co/mGQmxjhMet This is a new standard in scan engine optics. Nothing else comes close. These optics enable diffraction-limited imaging over a huge field-of-view. They're easy to integrate into your systems.

I have new posts and whatnot here:

I'm on mastodon because it's simple, clean, open, and a community. It's not perfect, but there's no profit-driven algorithm.

Bluesky is nice from what I hear, but it could easily run into the same issues. (1/3)

[Spencer LaVere Smith @Labrigger]

I'm on social media to share with technical communities in neuro, optics, computation, ML, etc. I don't need a free-for-all platform with the potential to reach millions.

Mastodon is a good fit for me. (2/3)

[Spencer LaVere Smith @Labrigger]

@BoninLab I'll try again right now.

[Spencer LaVere Smith @Labrigger]

The Nemonic discussion group (Slack-like Mattermost interface) is a nice place to ask questions and share info for 2p neuro and related topics. Join here or message me. https://t.co/crnqtW2V3G

[Spencer LaVere Smith @Labrigger]

I'm excited about this. If your experiments benefit from having a large field-of-view scanned fast at high resolution, this is beyond anything else out there. It's ready to go. If you want in early, email me and we'll let you know the details. No pressure. It's just very cool.

[Pacific Optica @pacificoptica]

Here are a couple of shots of one of our new products. Unlocking the widest fast scanning ever. Looking forward to sharing more about this new tech! https://t.co/fG3gFCU7MN See more. Measure more.

[Spencer LaVere Smith @Labrigger]

Called it.

[Fermat's Library @fermatslibrary]

2¹³⁶²⁷⁹⁸⁴¹−1, discovered today, is the largest known prime. It's a Mersenne prime (2ᵖ-1), which are easier to find.

It took nearly 6 years for the GIMPS software to find it after the previous largest known prime. It was also the first Mersenne prime found using GPUs.

We grieve the passing of Dr. Yves Frégnac.
Yves has shaped the study of cortical processing and plasticity. He heralded interdisciplinarity and was one of the founding fathers of our institute.
Our thoughts go to his family and to his friends in the community and beyond. https://t.co/BGE4QGcg8g
