cool new work from @ppiantad.bsky.social and the Holmes laboratory looking at how BLA neurons encode risk using a variety of approaches. check it out!

for anyone interested in the amygdala and risky decision-making, check out our new preprint: biorxiv.org/content/10.1...

amygdala neurons track reward-seeking actions, and punishment risk dramatically alters this function. lots of other (BLA-accumbens!) data included.
Risk reshapes amygdala representation of choice
Modifying behavior in response to changing environmental conditions is a crucial adaptive function. This capacity is exemplified when animals curtail pursuit of a valued outcome that risks being punis...

How do we associate the flavors we experience during a meal 🍽️😋 with postingestive effects like food poisoning 🤢🤮 that arise much later?

Our answer in @nature.com this week: Illness signals from the gut reactivate and strengthen flavor representations in the amygdala.

FYI @ahmarilab.bsky.social is still following up on this work if any trainees are interested 👀

Great opportunity to study behavior relevant for OCD🐀🧠 use cutting edge techniques🔬🧬 and have a supportive and encouraging mentor 🫶
Not to mention, Pittsburgh is the best 💛🖤

So happy to see this paper out! Congrats @victoriacorbit.bsky.social and @ahmarilab.bsky.social! Lots of fond memories from running these experiments. The similarity in the behavioral and striatal neural response time course produced by driving M2 inputs was really striking.
