The SPiNS lab is ready to share what we’ve been working on! Sonya, Steve, and Kate are presenting their projects at CEMS 2026. If you’re interested in the structure, dimensionality, and flexibility of semantic memory check out a sneak peak of their posters below 👇

I'm proud to say we are releasing LAION-fMRI, a densely sampled 7T fMRI dataset of natural images, with very broad stimulus sampling for testing countless hypotheses and for deeply exploring brain representations. The dataset is now available at laion-fmri.hebartlab.com What does LAION-fMRI offer? 🧵

LAION-fMRI - a 7T fMRI dataset of human vision

LAION-fMRI (LfMRI / LAION MRI dataset): 5 subjects, 25,052 launch-release natural images, 165 acquired 7T fMRI sessions with single-trial GLMsingle betas, retinotopy, localizers, and diffusion.

any other neuroscientists out there writing about Brian all the time or is that just me? 🧠 (highly recommend reading up on traumatic brian injury and all the brian regions of the human brian on pubmed sometime)

Super excited to share this preprint! How do we disentangle underlying structure from the particular features of a learning episode to benefit future learning? We find that memory reactivation during sleep promotes this structure abstraction process. www.biorxiv.org/content/10.6...

Curious what a representation of "everything" you know might look like? Wonder how you might fill it in? Check out our demo and paper (led by @paxt0n4.bsky.social and now out in @natcomms.nature.com ), or read on to learn more! Demo: context-lab.com/mapper/ Paper: www.doi.org/10.1038/s414...

We've posted a new fMRI study of semantic relations (has-part, is-a, made-of, etc.), a key aspect of language. We find that relations are represented in the same brain regions as are other semantic concepts, though voxels tend to be selective for only one relation or another. doi.org/10.64898/202...

kate, our lab tech, is doing some really cool work constructing concept networks from text embeddings and aligning them with human concepts. seeing the networks come to life is 🔥

2026 big update to the psycholinguistic database page! If you know of corpora, lexical databases, or other resources that I've missed, please LMK. Trying to keep this thing relatively current and could use the help www.reilly-coglab.com/data

⭐ My lab is recruiting a grad student for fall 2026! ⭐ 🧠 If you are interested in semantic learning & memory, and want to use fMRI + computational models to ask these questions, I'll be excited to hear from you. Come join us in Bing! 🔗 sites.google.com/view/spinslab

My lab is hiring! We have an opening for a full-time RA to focus on computational modeling and fMRI analysis. Programming skills are required. Psych/cog/neuro experience not necessary but a big plus. A great fit for someone who wants lab experience before grad school. Details and job link below ⬇️

See you at CNS! We’ve got new data suggesting that reactivating a recently learned category during sleep facilitates abstraction of category structure & promotes transfer learning to a new category. Transfer was not seen immediately or after a delay—only after sleep+TMR. w/ @annaschapiro.bsky.social

1. For the past thirty years I've had the best job in the world. 
I've had the opportunity to follow my curiosity; explore the workings of nature and society; mentor students and junior colleagues in the same process; and teach generations of students about it all.

wishing I could be rallying with the philly science community today—do some shouting for me!!!

Memory-sky: I'm going to be teaching a new (open!) grad course in the spring, where we read about and implement some memory models (and ideally for them to some small datasets). Looking for suggestions to include! I could go "classic" (Hopfield nets, SAM, TCM, etc.), or "modern" with newer stuff 🤔

🚨BREAKING. From a program officer at the National Science Foundation, a list of keywords that can cause a grant to be pulled. I will be sharing screenshots of these keywords along with a decision tree. Please share widely. This is a crisis for academic freedom & science.

going to a conference in your first semester as a PI see ya at #psynom24 !

🚨Job alert! My new lab at Binghamton University is hiring a full-time lab manager ("assistant"). This is a great fit for a recent grad looking for cog/comp neuro experience before grad school. Details below, feel free to reach out with questions! binghamton.interviewexchange.com/jobofferdeta...

Are semantic representations stable or plastic over time? VERY excited to share this preprint, revealing plasticity within the MTL: reps in parahippocampal cortex drift over ~8 months and are also rapidly reshaped within ~1 hour. w/ @annaschapiro.bsky.social www.biorxiv.org/content/10.1...

Recent statistics shift object representations in parahippocampal cortex

Our representations of the world need to be stable enough to support general knowledge but flexible enough to incorporate new information as our environment changes. How does the human brain manage this stability-plasticity trade-off? We analyzed a large dataset in which participants viewed objects embedded in thousands of natural scenes across many fMRI sessions. Semantic item representations were located by jointly leveraging a voxelwise encoding model to find reliable item representations and a word-embedding model to evaluate semantic content. Within the medial temporal lobe, semantic item representations in hippocampal subfield CA1, parahippocampal cortex, and perirhinal cortex gradually drifted across a period of multiple months. However, rapid plasticity was observed only in parahippocampal cortex, such that item co-occurrence statistics warped item representations within a single session. In conjunction with whole-brain analyses, these results suggest that the brain solves the stability-plasticity trade-off by promoting plasticity in only a subset of semantic regions. ### Competing Interest Statement The authors have declared no competing interest.

New preprint! We show that category structure rapidly warps memory for individual object features according to their roles in the category. Features shared across exemplars pull together while unique features stay apart. With @annaschapiro.bsky.social and Cody Dong. doi.org/10.31234/osf...

I'm recruiting PhD students to join my new cognitive neuroscience lab at Binghamton next fall! We'll use behavior, fMRI, and computational methods to explore how humans learn, represent, and flexibly use concepts in language and thought. If this excites you, too, please apply! tinyurl.com/42arf45f

Shamelessly using my first post on this app to share that I got married a few weeks ago! (from now on I promise my posts will be about science...mostly)
