Very excited to share our new preprint. We identify the basolateral amygdala dopamine system as an important interface between dynamic shifts in the environment and decisions to engage in vigorous drug use. Really challenging studies led brilliantly by Dr. Megan Brickner.
The basolateral amygdala dopamine system shapes dynamic drug seeking states
Drug-associated sensory cues and contexts exert powerful influence over drug seeking motivation, but in vivo brain mechanisms governing this process remain unclear. Here, we recorded and manipulated d...

🚨 new work from the lab! "Dissociable cortical-hippocampal dopamine dynamics support memory-guided behavior" by @albitc.bsky.social et al. congratulations whole-heartedly to the team and we're excited to hear everyone's thoughts on the work! 👇🏽 www.cell.com/current-biol...
🚨 new work from the lab! "Hippocampal astrocytic sequences emerge during learning and memory recall" by @ryguy.io & @rsuthard.bsky.social thank you to the entire team for your camaraderie and for muscling through science together 🧠 -- we welcome all feedback! nature.com/articles/s41...
Hippocampal astrocytic sequences emerge during learning and memory recall
Nature Neuroscience - Senne, Suthard and colleagues show that dorsal hippocampal astrocytes display time-compressed calcium-event sequences after foot shock and upon context re-exposure, and that...

new paper out, led by @jobeneuro.bsky.social , exploring 5HT dynamics in cingulate and central amygdala, and how a history of alcohol consumption changes them! www.nature.com/articles/s41...

Less immediately, I am hearing that NIH is overwhelmed with applications (not surprisingly) and they are sufficiently short-staffed in CSR that they will continue with the only discussing 1/3 (rather than 1/2) of the applications. There apparently will be a Notice about this soon. 3/3
Attention all central amygdala aficionados and habit learning lovers: Sharing the latest work from my time at Dartmouth where we examined CeA activity during habit formation, now out at JNeuro www.jneurosci.org/content/earl...
Habit learning shapes activity dynamics in the central nucleus of the amygdala
A habit develops as a motivated behavior that is strengthened by extended experience and feedback. While the performance component of a habit is relatively well studied, being linked to action-related...

When a student tells you they thought the amygdala only does fear learning and you see an opportunity to spread the Good Word

Fresh from the Castro Lab! We characterize how mu opioid receptors on pancreatic alpha cells regulate ingestive phenotypes. Surprise! Mu can act both inside and outside the brain😱 Congrats to our technician Diego De Gregorio! @ssibsociety.bsky.social www.sciencedirect.com/science/arti...
Pancreatic mu opioid receptors regulate metabolism and ingestive behaviors
The mu opioid receptor system has long been recognized for its role in regulating ingestive behaviors and food palatability. However, beyond their rob…

I am happy to share our latest manuscript, led by newly-minted PhD Justin Wang, identifying a neural population that selectively controls hedonic, but not homeostatic, feeding. www.biorxiv.org/content/10.6...
Ventral pallidal GABAergic neurons control hedonic feeding and obesity
Food intake is governed by two interacting drives. The homeostatic hunger drive regulates food intake to fulfill caloric needs while the hedonic drive promotes intake of palatable foods outside of cal...

Running a lab is like running a small business. When you run out of money, you close. Right now we are favoring incumbents and squeezing out the most vulnerable. Life saving research is abruptly shutting down and early career scientists are paying the price!
Thanks again to @michaeldgreen.phd for telling us how politicization of NIH funding has derailed early career researchers. Catch us every Monday 2pm on the #TraumaCode on WBAI 99.5 FM NYC podcasts.apple.com/us/podcast/t...

First Castro Lab paper, brought to you by the hard work of Dr. Kathryn Braden @katybraden.bsky.social In this manuscript we investigate the role of endogenous enkephalin or dorsal raphe nucleus. We find that it is incredibly important for buffering negative affect 😱 www.nature.com/articles/s41...

NIH spending on these 5 programs (F31, F32, F99, K99, DP5) grew $3M between FY2024 and FY2025. But new-award dollars fell $16M, and 337 fewer scholars received new awards (~-20%). I’ve seen claims about forward funding helping young scientist, how does it help us if we can’t get an award?
The NIH has canceled 48 early career training funding opportunities in the last year. elizabethginexi.substack.com/p/scientific...
Heads up to postdocs writing K99s out there, reviewers will want you to have already collected data with the tool you’re proposing to learn
