📣 Heads-up that our amazing dept (Berkeley Psych) is anticipating hiring *two* TT Asst Profs this Fall, under the themes of (1) Social & Personality Psychology, (2) Biological Basis of Behavior. Official job ads coming soon... Send qs for 1 to I Mauss/S Chen, 2 to L Wilbrecht

New preprint! tl;dr — We ran around late at night to record wild rats in NYC and figured out how to quantify their behavior and environment. 🧵 w/ Dima Batenkov, @zamakany, @e_mackevicius biorxiv.org/content/10.110…

I'm excited to share another piece from my PhD - and start of my postdoc! Based on our previous study refining heroin self-administration, we propose a choice procedure to identify individual differences in preference for heroin and social interaction. bpspubs.onlinelibrary.wiley.com/doi/10.1111/bp…

What’s better than a one-channel #Miniscope? 🥁 A TWO-CHANNEL Miniscope! Our new Miniscope2C is a dual-channel, open-source Miniscope that lets you record 2 fluorescent signals simultaneously in freely moving animals. Read the paper here: science.org/doi/10.1126/sc… (1/9)

GREAT NEWS! Our paper on dopamine signaling of valueless prediction errors is out in @ScienceAdvances! I found that striatal dopamine tracks cue-cue prediction errors in sensory preconditioning, which goes against model-free theories of dopamine function. science.org/doi/10.1126/sc…

Excited to share our latest paper in @npp_journal! Chronic CBD mitigates alcohol dependence, reduces withdrawal symptoms, & offers neuroprotection in BLA & striatum in rat AUD models. Congrats to 1st author @neuroselo! Thanks to @cmcr_ucsd funding for the pilot that sparked this.…

(1/3) Excited to introduce our new GRAB sensors for a series of steroid hormones! These tools enable real-time detection of steroid hormone dynamics in vivo🐭🧠.Happy to share these sensors and welcome any feedback!Please contact [email protected] for information.
