I first understood that you published with your husband and your wife - separate papers 😂

Hey, it's out!
doi.org/10.1016/j.ce... Aligning Big Brains and Atlases, ABBA in short, is published in Cell Reports @cp-cellreports.bsky.social . @biancasilvalab.bsky.social's lab added an analysis pipeline on top of it (BraiAn) and did all the relevant biological work. What is it ? Short thread:

Happy to finally publish this work… Congrats authors and thanks funders @agencerecherche.bsky.social #FondationBettencourtSchueller‬‬‬

These findings help to establish THG microscopy as a quantitative, multiscale imaging technique, paving the way for new applications. 📖 #Neuroscience #Myelin #THG #Microscopy #Research

Finally, we illustrate the relevance of pTHG microscopy for characterizing myelin distribution at different scales in fixed mouse and human brain tissue.

Fun fact for multiphoton microscopy geeks: aberrations caused by vertical micro-interfaces appear to be a significant contrast mechanism in polarized THG imaging. 😎

We show that axons exhibit complex pTHG profiles that depend on axon morphology and can't be explained by classical models. We establish a numerical strategy to relate pTHG profiles to axon diameter and myelin thickness, taking into account myelin-induced optical aberrations.

Our study presents a systematic characterization of polarized THG (pTHG) signals from individual axons, enabling the derivation of myelin scores in various systems. 🐭🐟
We confirm the sensitivity of THG for myelin in mouse tissue and detect early axon development in zebrafish.

Do you need to analyze your FLIM data with open source software?
The #Virtual #I2K2024 workshop on "Interactive #phasor analysis of #FLIM data using FLUTE" given by Bahar Asadipour is online. www.youtube.com/watch?v=q7W1...
#FLUTE can analyze data of most commercial cards

True, but it is also a matter of disseminating scientific knowledge. Biology has made tremendous and rapid progress in the last century, with consequences for medicine. (So has physics (not to mention computer science 😂)).
