Thank you so much to the NINDS for believing in my trajectory through this F32 award. Here's to the next phase of hard work learning exciting things about LV projecting ACC neurons in pain.

I am in tears today, so so so happy. Watch for our paper on mouse models of nocebo hyperalgesia, soon-to-be in press in #NatComms #Accepted! "Cholecystokinin input from the anterior cingulate cortex to the lateral periaqueductal gray mediates nocebo pain behavior in mice"

Interesting, mice are returned to a shock box and facial expressions analyzed. An alternative take though is that this is nocebo face. www.sciencedirect.com/science/arti...

Convolutional neural networks detected changes in facial expressions of mice that had conditioned fear stress
Animal models are essential for studying aversive states such as fear and pain. Facial expressions may provide non-invasive readouts of aversive state…

Such a fantastic experience at #USASP_2026 this year. Thank you so much to everyone who dropped by our poster on RMAs and for all of your feedback. Looking forward to showing this work and nocebo hyperalgesia (2 posters) at #CanadianPain at the end of April so please swing by if you're going. 🇺🇸🇨🇦

What's sad and mind-blowing is hearing the local businesses are really suffering this year because the universities and hospitals here in Philly aren't spending because the Trump administration put a squeeze on NIH and NSF funding. No parties that need catering, no flower orders, nothing like that.

Is it mirror neurons, or is it the perception in Perception Action Model of empathy: recognition of salient information in social partners. To me the cortical neurons in nocebo and are not bound to social interaction. How to handle it: look for the same neural patterns in contextual conditioning.

My arguments: 1) it was already like this for most postdocs for the last 3 decades 2) universities will always be a cheap place to train people how to think, which is what a phd is and 3) universities discover stuff in the process of training those phds journals.plos.org/plosbiology/...
