And the setup robustly works! After building it at @BU_NPC we reproduced it in my @ibs_bifold lab and ran more studies with this solution for colocalized #DOT-#EEG - zero crosstalk, great signal quality!.
😎 Fascinating new #multimodal work from Rogers et al (2025) introducing a co-localized #fNIRS - #EEG cap using custom grommet designs. High-density fNIRS optodes to attach directly to EEG electrodes, without interference. Read the full study here 🔗

Thanks @eikemiddell for representing our @ibs_bifold lab and providing the training for our #fnirs / #dot #python toolbox Cedalion. I am excited about 2025 and what we will be able to do kickstart with it! Thanks @AddisonBilling for the invitation and organization!.
Many thanks to @eikemiddell and the team at @ibs_bifold for the training course on how to use the Cedalion toolbox to analyse fNIRS data. Excited to see this open-source Python toolbox being used to analyse LUMO datasets! #fNIRS #Neuroimaging @cambridge_uni @AddisonBilling

Looking forward to this demo! Cedalion is our #opensource #python toolbox for advanced #fnirs and #dot processing - and the #coregistration feature using #photogrammetry is easy to adapt and use, and works also for other sensors such as #eeg and #oMEG.
Next Monday, Nov. 18th, 4pm, Berlin time. Join Alexander von Lühmann and Eike Middell at their Webinar: "Photogrammetric fNIRS optode registration on the head with the Cedalion toolbox: A tutorial".@avolu_neurotech @eikemiddell.

How much does #fNIRS signal quality depend on factors like hair and skin type, and how does that affect inclusivity? ☝🏿☝🏾☝🏼.See the preprint of our study with 115 participants that quantifies the answer, lead by a great team around @MeryemAYucel and @BoasDavid at @BU_NPC.

Recommendation to join! We are already frequently using #NIRFASTer in #cedalion and have an example Notebook for #DOT that is easy to run. You can choose either way of photon simulation (the other being MC with #MCX). More through here:.
Register now for a webinar with Dr. Jiaming Cao discussing a new algorithm combining DOT and EEG signals for improved neuronal source reconstruction. Learn about the updated Python-based version of NIRFASTer in the Cedalion toolbox to enhance your knowledge in the field. #webinar
