We develop a geometric theory of how neural populations support generalization across many tasks.

Very cool!!

Would love to be added too. Thanks Amy

Revisiting the high-dimensional geometry of population responses in the visual cortex with @jpillowtime.bsky.social. The review took forever because a reviewer was doubtful our new estimator can infer eigenvalues beyond the rank of the data! (1/6)

I have a PhD opening for my #VIDI BrainShorts project 📽️🧠🤖! Are you or do you know an ambitious, recent (or almost) MSc graduate with a background in NeuroAI and interest in large-scale data collection and video perception? Check out our vacancy! (deadline Feb 15).

New preprint: Confidence-accuracy dissociations in perceptual decision making. A review I was supposed to write 3 years ago for my VSS Young Investigator Award. Better late than never 😅 I tried to organize the literature and explore the likely mechanisms. Feedback welcome!

A distinct set of brain areas process prosody--the melody of speech Human speech carries information beyond the words themselves: pitch, loudness, duration, and pauses--jointly referred to as 'prosody'--emphasize critical words, help group words into phrases, and conv...

New preprint on prosody in the brain!

Prosody areas are distinct from pitch, speech, and multiple-demand areas, and partly overlap with lang+social areas→🧵

MOSAIC: A scalable framework for fMRI dataset aggregation and modeling of human vision Recent large-scale vision fMRI datasets have been invaluable resources to the vision neuroscience community for their deep sampling of individual subjects and diverse stimulus sets. However, practical...

Please reach out with feedback or if you feel we should include certain functions that would help you in your research!

Thanks to a data grant from @amazonwebservices.bsky.social MOSAIC has been publicly hosted online. Just pip install mosaic-dataset!

MOSAIC is community-led and is meant to be a living resource. Do YOU have a large-ish dataset you'd like to add to MOSAIC? Please contact us! You can do it yourself (if you prefer) or we can help you with it. Let's push the field forward together..

nterested in training models directly on brain data? MOSAIC has the scale and quality to do this well!
Ben and Mayukh trained several models directly on MOSAIC (see preprint). You can do this easily as well!

nterested in computational modeling? MOSAIC provides careful test-train splits of the data ensuring that there is no data-leakage! (Something I think is very much needed and IMO missing from the field. More on this later though).

MOSAIC aggregates data from 8 publicly available fMRI datasets (93 subjects, >400k trials, and 163k individual images). Each dataset has been re-analyzed from scratch, and preprocessed using SOTA methods (GLMSingle
@jacob-prince.bsky.social , Kendrick Kay and colleagues)

Need more fMRI data (beyond the amazing NSD)? Introducing MOSAIC! Incredible effort led expertly by Ben Lahner, with help from grad student Mayukh Deb. Work in collaboration with the amazing Aude Oliva! @neurosky.bsky.social. More below..

Investigating individual-specific topographic organization has traditionally been a resource-intensive and time-consuming process. But what if we could map visual cortex organization in thousands of brains? Here we offer the community with a toolbox that can do just that! tinyurl.com/deepretinotopy

Applications due December 1st!
Come work with us!

Excited to share our work on mechanisms of naturalistic audiovisual processing in the human brain 🧠🎬!!

What happened when you told him? Curious abt his reaction 😂

Fantastic! Congratulations Iris

Delighted to share our new paper, now out in PNAS! www.pnas.org/doi/10.1073/...

Thank you, Jane Goodall

Excited to share new work with @hleemasson.bsky.social , Ericka Wodka, Stewart Mostofsky and @lisik.bsky.social! We investigated how simultaneous vision and language signals are combined in the brain using naturalistic+controlled fMRI. Read the paper here: osf.io/b5p4n

Thanks Tahereh! I’ll unfortunately not be at Neurips this year but will request Herrick to reach out directly. I’m sure he’d appreciate the feedback. He can also tell you about other things works and esp things that don’t work as well.

At Neurips? You can now check out @herrickfung.bsky.social ‘s new work on modeling individual differences at two workshops! Much more to say on this awesome colab with @dobyrahnev.bsky.social very soon. 🙂

Neuronal signatures of successful one-shot memory in mid-level visual cortex High-capacity, one-shot visual recognition memory challenges theories of learning and neural coding because it requires rapid, robust, and durable representations. Most studies have focused on the hip...

New preprint! How can you remember an image you saw once, even after seeing thousands of them? We find a role for humble mid-level visual cortex in high-capacity, one-shot learning. doi.org/10.1101/2025.09.22.677855 🧵🧪1/

ATTN🚨: I will be looking for PhD students through NYU's Center for Data Science PhD program this year. Applicants should have an interest in either NeuroAI (specifically biological attention or AI interpretability) or ML for Remote Sensing. Visit my lab website for more info: lindsay-lab.github.io

What fun to hang out in Amsterdam with former lab members, dear friends, and scientific rock stars @evfedorenko.bsky.social‬ @lisik.bsky.social‬ @apurvaratan.bsky.social‬ @carolinerobertson.bsky.social‬

Omg seeing this just now. Happy birthday Iris!
