Excited to share my PhD paper! In it, we use targeted 2-photon optogenetic stimulation to determine how V1 activity is read-out in a detection task. We found that network influence, not visual coding properties, predicted the impact of ensembles on behavior - contradicting our expectations (1/5).

Our lab is hoping to hire a long-term lab manager / research associate to help with admin tasks and neuroscience experiments (3-year minimum commitment). bilh.wd1.myworkdayjobs.com/External/job...

Congrats Marta on a very strong effort!

Out now in @nathumbehav.nature.com: Cuts to NIH funding will impact the economy and employment nationwide. We visualize these losses and advocate for a theory-driven approach to communicating local, self-relevant impact. w/ @joshuasweitz.bsky.social + SCIMaP team: www.nature.com/articles/s41...

Wild! Stephen, Praneel and their team use fluorescence lifetime imaging and various manipulations to show that, in male mice, both mating drive and hypothalamic tonic dopamine release drop after a successful mating and gradually recover over the next week, paralleling the recovery in sperm count.

Disruption of visual cortical activity and offline reactivations of recent salient experience in the hours following training on a task associating cues with outcomes completely blocks across-day learning! Exciting work by Kristian, Marianne and their team!

We previously showed that specific hypothalamic neurons get more and more activated by each bite of food until they put a brake on homeostatic feeding. Here, we find that this brake is already on at the start of a meal in obese mice on a high-fat diet. Congrats to Marta, Stephen and the whole team!

Academic workers across the country are calling 📞 Legislators to ask them to sign on to bipartisan letters ✉️ in support of robust NIH funding and opposing the 15% indirect cost caps. Take 5 minutes to call your legislators today. Deadline is May 19th. docs.google.com/document/d/1...

A drop of milkshake takes a wild ride as it passes through the body. Rachel and Kiersten and the team came up with cool strategies for visualizing food passing through the mouse GI tract and mapping the activity of the same 100s of brainstem neurons across weeks during feeding and other behaviors.

🚨iGluSnFR4 is finally out!🚨🧪 We present iGluSnFR4f and 4s, a novel pair of genetically-encoded glutamate indicators designed for high-fidelity imaging of synaptic activity in the living brain. ⬇️ www.biorxiv.org/content/10.1... 🎥 Below: iGluSnFR4s detecting minis in cultures w/ TTX #Neuroscience

New report shows that NIH grants fueled $95 billion in economic activity and 407,782 jobs in 2024. That's not to mention the countless lives that biomedical research has saved. Show me a better investment than that. www.forbes.com/sites/michae...

We lack tools to rapidly track >1-2 changing signals in brain fluids. Peter Kalugin and an amazing team begin to address this challenge with simultaneous, real-time tracking of many (10+) neuromodulatory signals using Multiplexed Optical Recording of Sensors on a micro-Endoscope. Feedback welcome!

Stephen Zhang and the team found that in vivo peptide release and signaling gradually enhances responses of satiety-promoting hypothalamic neurons to each bite of food. These consequences of each bite take minutes to manifest, and could help explain why slow eating enhances satiety. rdcu.be/dZlI3
