RECRUITING!

I am establishing my new lab at Weizmann Institute (www.weizmann.ac.il/chembiophys/...) and am recruiting at the Senior Intern/Staff Scientist track, & at the Postdoctoral, PhD, MSc, and Technician levels. All positions are fully funded- I warmly welcome applications from outstanding candidates.

New website! still a bit rudimentary, but hopefully will be updated soon! :-) Stay tuned for job postings (in the meantime you can check the "join us" tab if you are interested!) www.weizmann.ac.il/chembiophys/...

Come work with us. Huge strengths in MRI, neuroscience and musculoskeletal health and their intersections such as pain, child development or ageing. Preclinical and clinical research and translation are also big opportunities. Shoot me a note if you have questions.

The ultrahigh field 18 Tesla @brukercorporation.bsky.social MRI Scanner has just arrived to @champalimaudr.bsky.social! Along with its cryoprobes, it is expected to be the most powerful preclinical scanner in the world. Ramping up will take time... will keep you posted!

@champalimaudf.bsky.social just installed a custom-built 18-Tesla horizontal-bore MRI scanner – the strongest for in-vivo imaging – to advance preclinical research non-invasively in neuroscience and cancer. Full story: shorturl.at/pGREa #PreclinicalResearch #Neuroscience #Cancer #MedicalImaging

The paper demonstrating that #psilocybin alters contextual computations is out in @natcomms.nature.com : doi.org/10.1038/s414... Thanks to the reviewers and coauthors : @marcoaqil.bsky.social , @tknapen.bsky.social , @gillesdehollander.bsky.social , and Nina Vreugdenhil

New preprint from the lab on stroke and oscillations detected via ultrafast fMRI! www.biorxiv.org/content/10.1...

Great coverage by @thetransmissions.bsky.social of our latest preprint: adding new evidence (and a hint of controversy 🙂) to the E/I imbalance debate in autism 👇👇 www.thetransmitter.org/spectrum/ram...

Unlike the heart attack of getting a “Decision” email, it’s such a good feeling to get a “Your review is ready” email from qed :)

BIG ANNOUNCEMENT📣: I haven’t been this excited to be part of something new in 15 years… Thrilled to reveal the passion project I’ve been working on for the past year and a half!🙀🥳 (thread 👇)

Tried this on a very technical fMRI manuscript with neuroscience applications. It warned me that neuroses outside its core expertise, but then proceeded to present an amazing analysis of the claims in the paper. Vastly superior to ChatGPT for example. I am impressed!

The things we can do @westernu.ca thanks to platform support grant funding from @braincanada.bsky.social And #NFRF

Even though the controversial DIANA method didn’t pan out, neuroimaging researchers still hold out hope to one day measure neuronal activity using fMRI. By @callimcflurry.bsky.social www.thetransmitter.org/retraction/a...

New paper in Imaging Neuroscience by Roza G. Bayrak, Catie Chang, et al: DeepPhysioRecon: Tracing peripheral physiology in low frequency fMRI dynamics doi.org/10.1162/IMAG...

A new open source nonsurgical head restraint for awake mouse fMRI from our lab led by Sam Laxer. TL;DR Scanning about 25% longer than with a surgically implanted head post, combined with some training gives good results. Happy mice = happy rsfmri networks. direct.mit.edu/imag/article...

Science is self correcting. Finally!

A method for capturing neuronal activity using fMRI excited the neuroimaging field but couldn’t be replicated. Today, the authors of the original paper retracted their work. By @callimcflurry.bsky.social #neuroskyence www.thetransmitter.org/retraction/a...

An important retraction of the DIANA paper. Scientific progress is often made by correcting prior efforts, and here the community played its part efficiently. While this particular form of mapping neural activity was unsuccessful, the search continues! www.thetransmitter.org/retraction/a...

New paper in Imaging Neuroscience by Marie E. Galteau, Joanes Grandjean, et al: Activation mapping in multi-center retrospective rat sensory-evoked functional MRI datasets using a unified pipeline doi.org/10.1162/IMAG...

direct.mit.edu/imag/article... NEW PAPER! After many years in the making... we present evidence that BOLD-fMRI can detect push-pull interactions in subcortical areas. Congrats to Frederico Severo and Mafalda Valente!

More fields need to do this.

Another new paper from the Lab, with a multimodal fMRI / CBF / cFOS approach in an animal model of Parkinson's Disease! Congrats @ruxandalungu.bsky.social @ciscaff.bsky.social, Sara Monteiro and our great collaborator Tiago Monteiro! journals.sagepub.com/doi/10.1177/...

🧠👁️A SC push-pull interaction during the dynamic vision mode, revealed with fMRI and brain lesions, challenges the notion that intertectal connections solely serve as reciprocal inhibitory mechanisms for avoiding visual blur during saccades. @shemesh-lab.bsky.social doi.org/10.1038/s420...

new paper from the Lab, harnessing fMRI and lesions to reveal some interesting "push-pull" interactions in Superior Colliculus! Check it out here www.nature.com/articles/s42...

1/ Six years in the making! Our preprint on SORDINO fMRI is out. We're sharing the raw data and sequence to facilitate brain-wide mapping in awake, behaving rodents. If this could be useful to your colleagues and friends, please help spread the word! www.biorxiv.org/content/10.1...

AMAZING opportunity, don't miss it!

It’s the honour of a lifetime to be elected as ESMI's President-elect. Thank you for your faith in me. I will work hard to promote the values of the Society to a broad audience and be a strong advocate for the discoveries you have made in molecular imaging. 🙏🏻 www.kcl.ac.uk/news/profess...

check out our new preprint! Together with Joana Carvalho and Koen Hak (and co-authors) we developed an ultrafast fMRI with layer resolution, and show how feedback/feedforward signals can be mapped from a layer connective field model www.biorxiv.org/content/10.1... MORE in a few weeks!

🔍 New must-see resource! 🧠 --> Reproducible Brain Charts – an open-data tool for mapping brain development & mental health www.biorxiv.org/content/10.1... 👏 Kudos to @ted-satterthwaite.bsky.social and Michael Milham @childmindinstitute.bsky.social for leading this effort!

Consistent with earlier publications, the #PETALUTE sequence features enhanced incoherent sampling for compressed sensing (CS). Through simulation, phantom, and in vivo comparisons, results demonstrate PETALUTE's competitive performance against conventional nuclei #MRSI and #MRI methods.

Our first experimental demonstration of changes in diffusivity and kurtosis in the rat somatosensory pathway, where BOLD responses are not detected. Congratulations, Andreea Hertanu! @snsf-ch.bsky.social @fbm-unil.bsky.social

Dear wonderful imaging community, I'm running for (vice)president of the European Society for Molecular Imaging - ESMI. A society I care deeply about. The election opens on 18th February for all members of the society. I would be very grateful for your vote. 🙏 Tim
