We have a new preprint which characterizes characterizes two arteries that form the major blood supply to the hippocampus using in vivo Time-of-Flight (TOF) MR angiography 3T on 7T and . 🍤. We used compressed sensing to substantially reduce scan time and compare vessel diameter estimates and CNR.

Sharing the latest from the lab. Led by Yunlong Liu, this work explores how microglia and engram neurons interact during fear extinction in the hippocampus.

Nature Neuroscience - Liu et al. show in mice that microglia are recruited to the soma and dendritic processes of fear engram neurons during extinction learning and that they weaken fear memories...

Asking: is curiosity a homeostatic drive, or a policy learned through reinforcement?
How can we tell, and why does it matter? 🧵👇

Saturday was a good day for a fun chat about dreams and stuff with Katherine Bell on her podcast "the Dream Journal" (on ksqd.org/the-dream-jo...) - www.youtube.com/watch?v=fQ4H...
Human curiosity is dynamic, however the principles governing its fluctuations remain
debated. Here, we test two competing hypotheses about how past...

New paper from our group out in @pnas.org! doi.org/10.1073/pnas.... Big thank you to coauthors @vosstacular.bsky.social and @anikka-jordan.bsky.social. Anikka spearheaded this project during her time as an RA and is now a grad student at Yale.
For more than a century, the study of brain lesions has been central to understanding cognitive processes and normal brain function (e.g., Broca’s studies).
However, what electrophysiological signatures emerge following a brain lesion?
What drives human curiosity? Is it a need to balance stimulation — or something we learn over time?
In our 🚨 new preprint, we show that learning reinforces curiosity, especially for related content.
