We found that in vivo peptide release and signaling gradually enhances the response of satiety-promoting hypothalamic neurons to each bite of food during a meal. These consequences of each bite take minutes to manifest, and could help explain why slow eating enhances satiety.
I am thrilled to share the published version of our study on how neuropeptide signals regulate feeding in the hypothalamus! We imaged endogenous peptide signals in subcellular compartments during behavior. Below is an updated summary: rdcu.be/dZlI3
I am very excited to share new paper! We dissociated food need and motivation via normative framework and calcium imaging :) Thanks for amazing members @HyungGoo_Kim @HyungJinChoi_ @bbbining and Jong Won Yun 👍 science.org/doi/10.1126/sc…
Postdoc Fellow Opportunity‼️ Looking for a PhD in freely moving ephys to apply for this amazing Postdoc Fellows program to do wireless triple neuropixel ephys in the Agouti in the rainforests of Panama! Lets figure out what the brain does in nature 🔔please RT!
MindCORE Postdoc Fellowship @Penn Apply by Dec 1, 2024 Designed for new(ish) PhDs in neuro, psych, ling, philo, CIS, cog sci+ 3 yrs salary +20K research fund More: mindcore.sas.upenn.edu/post-doctoral-… Pls RT @whartonknows @PennEngGrad @AnnenbergPenn @PennLinguistics @PennBiology @PennNGG
More discoveries about IPN! (one of the players in head-direction system in vertebrates (at least in zebrafish)) So exciting🤩
New lab preprint! 1/7: If you are just like us, you have probably spent years wondering about the structure of the interpeduncular nucleus (IPN). The wait is over! Read our new bioRxiv preprint: doi.org/10.1101/2024.1….
So cool! Congratulations @joshsselfe 👏🤩
Ever wanted to explore the driving forces underlying inhibitory neuronal signalling? We did! So, for my MSc in @JosephRaimondo lab, we developed the all-optical approach ORCHID - all-Optical Reporting of CHloride Ion Driving force. Now out in @NatureComms nature.com/articles/s4146…
In what organism might your research questions be most tractable? Tiny, transparent Danionella fishes could be the ticket to uncovering general principles of brain-wide circuits. Also, they make sounds. And some have fangs. Read more here: nature.com/articles/s4159…
Amazing lab with great questions and very cool model, transparent singing fish! Check it out if you are looking for a postdoc.
We’re seeking a postdoc/student excited about animal communication, brain-wide circuits, microscopy, singing fish (@danionella), wacky ideas and who likes to: get things done, experiment, analyse, ask, learn, help and cooperate. jlab.berlin Please RT
Come this afternoon to our posters to see how pupil dynamics organize memory replay, how the hipp balances reactivation and homeostasis, how hipp-cortical interactions evolve during learning, and the neural mechanisms of foraging and territory formation in natural enviroments
Looking forward to meet everybody and enjoy the science once again this #SfN24 ! The lab is presenting several posters, most of them on Sunday afternoon. Stop by to chat, check out what we have been up to this year and meet our amazing students and postdocs 🤩
📢We are looking for a postdoc to follow up on these results. How do depth-selective responses arise and are transformed across the visual hierarchy? How do V1 neurons encode depth in freely moving animals? Please RT and get in touch if you are interested! crick.ac.uk/careers-study/…
Thrilled to share the first preprint from the lab! We find that mouse V1 contains a three-dimensional map of visual space with different populations of neurons responding to near and far visual cues! Led by @yiran25_ with @populusalba9 and @ant_blot biorxiv.org/content/10.110… 1/n
Xinyue and the team did an amazing job! Congratulations 🎉 Xinyue even developed a completely new prep for 2p imagining of food moving to the stomach of the fly!🔥
My PhD paper is out! We imaged gut neuron activity in living, eating flies (first time in history!), and found a Gut-Brain-Gut neural circuit loop that allows fruit flies to adjust their ingestion bouts based on the sucrose concentration of the food! (1/n biorxiv.org/content/10.110…
Congratulations to my labmates! Such a beautiful project!🔥💪
An incredible force of nature in our lab @karaba08 and the best interneuron hunter @heathlarsson, along with collaborators, amazing @ryaneharvey and @YYC356, made some cool findings: during sleep, our brain consolidates but aso reset memories. @antferrui science.org/doi/10.1126/sc…
It is so great to be at the course again🔥
Days 16 to 20 at #CSHLimaging2024 have been a whirlwind of excitement. I got the chance to sync #mini2P data with #freelyMoving mouse #behavior. My goal? To see how #neuronalActivity ties into #directionChange in an #openField. Data recorded at 14.6 fps (16X fast-forwarded)
Congratulations @TravisDGoode 🎊🤩
🎉🎉🧠🧠🔬🔬🥼🥼🧬🧬 Big day! New @AmarSahay_ lab #preprint! Please share! Feedback welcome! 🍫🍫🍩🍩🍦🍦🔥🔥 Here we identify a unique cell-type and circuit in the brain 🧠 that regulates context-dependent feeding! 🍫🍫🍫 🧵… 1/9
Wow, that was magical! Such a great meeting! Thank you @HypothalamusGrc, this conference was just awesome! So many great ideas, discussions and amazing people❤️ So grateful to participate and learn so much!🙏
We wrapped up Day 5 of the #CSHLimaging24 course by diving into the fundamentals of lasers and the basics of #2PhotonImaging! Tomorrow, we head straight to the lab to finalize our build ups of two-photon (2P) systems. Stay tuned for images captured using our setups!
