We find that chronic nicotine, when administered to adult mice, decreases dopaminergic neuron spontaneous firing rate and rebound activity. These effects could protect the neurons by decreasing their metabolic load.

The reason for this is that nicotine's protective effects seem to be only preventative, in that it reduces the risk of developing Parkinson's, but doesn't have a therapeutic effect on symptoms or disease progression after diagnosis.

Excited to share our new findings on how chronic nicotine changes dopaminergic and cholinergic neural activity. biorxiv.org/content/10.648…

Interested in doing you PhD at Georgetown? Come chat with students and faculty at grad fair booth 48A. #SfN25

Our lab has 2 great posters at #SfN25 this year! Plus a collaborative poster. Come see us Wednesday afternoon to learn how brainstem connections process sensory stimuli.

@lvolpic Yeah right from the start he's pouting in his tent, lol.

@cellularscale i have heard of him as some great hero. he is so annoying. I am on Hector's side 100%

Just finished the Iliad. My synopsis: A lot of battles, Achilles is a whiny bitch

#nokings in Prince William County, VA yesterday. Peaceful, positive. People chanting "we love america".

@ewadorotaz Thanks!

@cellularscale congrats Rebekah!

Excited to share our version of record in eLife! We find that two ways of inhibiting a brainstem structure (PPN) actually result in completely different and even opposite behaviors. One inhibitory connection is rewarding and one is aversive. doi.org/10.7554/eLife.…

@DautanDaniel Thanks! We actually show that the snc projections, not the snr input increase movement (see supplemental figures), and likely through antidromic stimulation, not through actions in the PPN. However, the rewarding and aversive effects don't appear to require antidromic activation

@cellularscale Congrats. Will have to check that one, the SNr ChR2 increasing locomotion is interesting.

Exciting work from the lab on unique DA subpopulation! SN pars lateralis DAN firing differs from SNc in super interesting ways. We find robust auditory CTX input and test in threat behavior. Congrats to Lorenzo Sansalone (@newrochemist), @cellularscale @e_twedell, Sherry Zhang!

"Female academics also have disproportionately fewer Twitter followers, likes and retweets than their male counterparts, regardless of their Twitter activity levels or professional rank." ihenow.com/2OVuRPz It's time to change this. Let's make today #FollowWomen day!

Reminder that CU Boulder is hiring three tenure track neuroscientists, broadly defined. Info/application here jobs.colorado.edu/jobs/JobDetail…

Michel Fallah, from the lab of 2023 Stanley Fahn Awardee @cellularscale, presented her meticulous physiology work on the differential inhibitory inputs to PPN neuron populations. Great work!

Thanks to @BenSaunders for posting his lab's sfn posters yesterday. I am 100% copying him here.

The lab is presenting 4 exciting projects at #SfN24 #SfN2024 this year! See you all Saturday afternoon and Monday morning. @SfNtweets

We are hiring 3+ Neuroscience faculty at CU Boulder! Seeking applicants with outstanding research programs in cell/molecular neuroscience, behavioral neuroscience, and integrative physiology. #academicjobs @FuturePI_Slack @NeuroRumblr jobs.colorado.edu/jobs/JobDetail…

@TaliaLerner Wow! Congrats, that is huge!
