🚨New paper alert: Excited to share our journey to contrast how multiple dopamine sensors respond to acute morphine treatment. We first compared changes in dopamine transients in rats prepared with VTA DA GCaMP6f, NAcLS dLight1.3b or GRABDA2h 1/5

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!

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

Happy Halloween from the Roitman labs! And thanks to @racheldonka.bsky.social for printing us festive, seasonal earrings!! @mitchroitman.bsky.social

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...

TODAY IS THE DAY! 🧪☀️⬇️ Join us at the Lincoln Memorial or your local site to Stand Up for Science!

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.

So much fun working with @basedownloh.bsky.social, Samantha Hurh, @racheldonka.bsky.social, Paula Bazzino, @atkeinath.bsky.social and @jamiedroitman.bsky.social We also had a really positive experience with #eLife and thank @flagel-lab.bsky.social and Michael Taffe for serving as editors! 4/end
