My fMRI study from the Mack Lab (@drmack.bsky.social) is now published on JNeuro! Here, we look into how hippocampal subfields flexibly update category knowledge representations in the face of novel exceptions. Check out the article here: doi.org/10.1523/JNEU....

Distinct Hippocampal Subfield Representational Shifts Underlie Category Exception Learning

When we encounter an exception to our prior category knowledge, such as a leaf-like butterfly that perceptually diverges from the butterflies we commonly see, we must update our knowledge to reconcile...

How do hippocampal pathways contribute to learning regularities and exceptions? To answer this, Melisa Gumus & @drmack.bsky.social use diffusion imaging to identify the endpoints of different hippocampal pathways, and then analyze functional activity within those "footprints". Super innovative!

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.

A neural state space for episodic memories

Episodic memories are highly dynamic and change in nonlinear ways over time. This dynamism is not captured by existing systems consolidation theories …

This is one of the most exciting pieces of science I have had the privilege to be involved in, led by @rui-xu.bsky.social‬, Bob Desimone, and Mark Richardson: the discovery of actual long-range monosynaptic connections in the human brain! For example the FFA connects to the rTPJ, how cool is that?

Reparative microglia persist in the brain after stroke but become dysfunctional through ZFP384-mediated mechanisms; however, this process can be mitigated by targeting Zfp384 using therapeutic an...

Children get better at reasoning from memory as they grow up. But is it the same brain process getting stronger, or something more fundamental changing? In our new paper, we use fMRI and computational modeling to test that question directly 🧵

Attention fluctuates over time and across contexts—how is this reflected in the brain?🧠 Fitting a dynamical systems model to fMRI data, we show that the geometry of neural dynamics along the attractor landscape reflects changes in attention.
