Happy to share our work on CFC paradigms using head-fixed mice in VR. We elicited freezing as a conditioned response, making the paradigm comparable to freely moving setups and compatible with techniques requiring head fixation, like 2p microscopy/stimulation. #neuroscience 🧠 doi.org/10.1101/2024...

🚨📃New Wassum Lab Paper📃🚨

Out today, @jackiegio.bsky.social discovered brain pathways that support agency and habit and how chronic stress disrupts them to rob of us our agency and cause us to form rigid habits 🧵👇

Adaptive decision-making often requires an understanding of our agency in a situation; however, chronic stress can disrupt agency and promote inflexible, habitual behaviour by turning off a brain path...

I know this site only reaches a subset of neuro/ cog professors. If you know a young professor in the area who would benefit from a week of targeted learning about doing good science, good mentoring, networking etc, it would be great if you could forward them: compneurosci.com/Neuro4Pros/i...

📣 As promised, here is our protocol paper on chemotagging! This new technique combines calcium imaging with chemogenetics to identify cell types in commonly used Miniscope recordings & can be used to tag ANY CELL TYPE! #Neuroskyence

Apropos of everything 🌎, we're declaring it "Fear and Anxiety Week" here on Bsky. It's like shark week but better!

This week, we'll hear about fear and anxiety from brain researchers, psychiatrists, clinical psychologists, and individuals with lived experience.

We invite you to chime in! 1/n

What if… spontaneous neural activity 🧠 reflects the baseline rumblings of a brainwide dynamical system initialized for learning? We find that the rumblings have macroscopic properties like those emerging from linear symmetric, critical systems 🧵 #neuroscience #neuroAI www.biorxiv.org/content/10.1...

Bummer that @zachtpennington.bsky.social is missing #ACNP2024 due to stomach flu. But be sure to check out his discovery about how the anterior hypothalamus codes stress 👇

This is one of the most important, surprising, and exciting findings I've been a part of!
❓ Do you know what the anterior hypothalamic nucleus (AHN) does? No? Neither did we! 🧠

In a new preprint from the Cai Lab, learn how we discovered the AHN’s central role in regulating stress vulnerability.
