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? 🧵
Excited to see our paper describing a stereotyped receptor map for smell (led by @davidhbrann.bsky.social ) out in the world! See below for short thread with open access link to paper

Decomposing representational drift across wake and sleep https://www.biorxiv.org/content/10.64898/2026.03.31.715372v1
Sleep ripples drive single-neuron reactivation for human memory consolidation https://www.biorxiv.org/content/10.64898/2026.03.27.714528v1
🔔 Preprint: “Hippocampal ripples evoke a stereotyped cortical response followed by spindle-mediated network synchronization.”
Combining iEEG+scalp EEG during sleep, we show that hippocampal ripples leave a decodable cortical fingerprint and are followed by brain-wide spindle synchronization!

How do experiences reshape our internal representations of the world? @bstaresina.bsky.social &co show that learning sequential experiences reshapes how the #brain represents what we see; a post-learning nap strengthens these predictive changes @plosbiology.org 🧪 plos.io/4dJGwMC
