From secretly watching her SfN talk on zoom during the pandemic to watching her crush her PhD defense, my bestie did it! Congratulations to the new Dr. @racheldonka.bsky.social ! We are all so proud of you!

Beach day in the Roitman labs’ meeting #cornsweat #jamiestrainees #mitchsriches @racheldonka.bsky.social @jamiedroitman.bsky.social @mitchroitman.bsky.social
Photometry phriends preprint: excited to share @racheldonka.bsky.social's side quest to validate how multiple sensors of mesolimbic signaling respond to acute morphine treatment - with @mitchroitman.bsky.social and @basedownloh.bsky.social

Question of the day: Will we win our dept’s annual holiday drink contest?
Seeing my trainees flourish at #SSIB2025 is special. @ssibsociety.bsky.social always does such an amazing job centering the work of early career investigators.Thrilled that @basedownloh.bsky.social won the Harry R Kissileff Award for outstanding talk by a postdoc and we could celebrate as a team.
Scientist in photo is taller than they appear!! Always a thrill to share our work at @ssibsociety.bsky.social! Love working and showing off my dream team (i.e., Roitman Labs). #mitchsriches
Bonita Springs -> Tromsø -> Oxford. Wrapping up my summer talk tour at #SSIB2025 today! Come join us to learn how Semaglutide-induced conditioned taste aversions impact dopamine signaling to sucrose at 4PM in L1.
Very excited to share our new paper on the effects of adolescent opioid exposure on reward sensitivity during initial morphine administration and withdrawal, as well as during and after re-exposure in adulthood! Now out in Physiology & Behavior: www.sciencedirect.com/science/arti...
It doesn’t matter how many degrees you have, getting shipments with dry ice will always lead to a good time.
Swapped a big tv for three projector screens and a Britney Spears mic. It felt like a dream to present our work at @ibnsconnect.bsky.social hosted in Tromsø last week. Awesome time meeting new peers/friends in 24/7 sunlight!
Biiiiiiiiiiiiig TV. It was awesome getting to share some recently published work and ongoing experiments with everyone at @achems.bsky.social ! So grateful for the opportunity and the fun discussion that followed.
Our VoR (doi.org/10.7554/eLif...) is out! See how phasic DA to sucrose flips and changes during acq., maintenance & ext of a conditioned taste aversion. Makes for great reading on your way to your local @standupforscience.bsky.social tomorrow!
Dopamine activity encodes the changing valence of the same stimulus in conditioned taste aversion paradigms
Phasic dopamine cell body activity and release in the nucleus accumbens differentially respond to the taste of sucrose in correlation with its hedonic valuation.

Completed my T32 fellowship with UIC’s Division of Endocrinology, Diabetes and Metabolism and got this neat award! Thank you to Drs. Xu, @mitchroitman.bsky.social, and Unterman for their mentorship and the reminder to bring a step stool to future photo opps.
Ringing in the New Year in Italy with some swag from last SfN. This post isn’t sponsored (but it could be??).
Since I've been here for a while… here are some useful features on Bluesky that you might not have discovered yet! 🧵
I don’t always post on social media…but when I do, it’s to share our new pub in #elife! Via conditioned taste aversion paradigm, we show dopamine and behavior responses to an intraorally delivered sucrose when sucrose is appetitive versus aversive. Fav part: the dopamine to behavior correlations!

Mitch Roitman@mitchroitman.bsky.social · 2y agoJust in time for Thanksgiving, we're grateful for the publication of our paper in #eLife doi.org/10.7554/eLif... We measured dopamine and behavioral responses to intraorally delivered sucrose across acquisition and extinction of a conditioned taste aversion. 1/n
