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). Please RT! https://t.co/t3GdEsEX20

@martaapp @StephenXZhang @harvardmed @nyuniversity Congrats Marta on a very strong effort!

NEW: Mark Andermann (@andermann_mark) of @harvardmed and @BIDMChealth brings experimental data and computational modeling together to understand cortical reactivations. Watch the video:

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.

Nice work, Marta & team!

🚨Paper alert!
📣  We found abnormal feeding-related neural responses in satiety-promoting, MC4R-expressing neurons in the mouse paraventricular hypothalamus (PVHM-C4R) following diet-induced obesity. https://t.co/8pBvZAGcvU ​#obesity #feedingbehaviour #obesityresearch

A drop of milkshake takes a wild ride after it is swallowed. Rachel and Kiersten 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.

I’m so excited to share our preprint on how brainstem neurons sense and integrate multiple body signals during food consumption. We imaged 1000s of neurons across the lateral parabrachial nucleus (LPBN) in behaving mice. https://t.co/OB6dozSeMZ

We lack tools to 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 (MORSE).

[Peter Kalugin @pnkalugin]

I’m thrilled to share our preprint presenting MORSE: a new way to simultaneously and quantitatively track patterns of neuromodulators/neuropeptides in vitro & in vivo using spatially multiplexed 3D imaging of 10+ green optical sensors on a microendoscope.

Eight days left to submit your abstract for the 2025 Keystone Symposium on Brain Body Communication at the Allen Institute for Brain Science in Seattle! Join us in exploring the latest in interoception research. Please repost, thanks!

[@markandermann.bsky.social @andermann_mark]

Come explore emerging research in brain-body communication @KeystoneSymp Interoception: Neural Sensing and Control of Organ Function, this April in Seattle! https://t.co/l6KIgl5sSd #KSInteroception25 https://t.co/57McwPKaAL

[Amelia Douglass @AmeliaMDouglass]

I am thrilled and grateful to share that I’ll be starting my lab at @ISTAustria in June 2025! We will study how the hypothalamus maintains homeostasis in response to challenges. Check out our website: https://t.co/y7e7atzcTr, and if interested please get in touch!

@rolls_asya Thanks!

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.

[Stephen Zhang @StephenXZhang]

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: https://t.co/ONFDccZXc5

[@markandermann.bsky.social @andermann_mark]

In other words, perhaps we should consider slowing down and savoring each moment.

Pretty exciting result: disrupting cue reactivations in mouse visual cortex in the hours *after* operant training completely blocks learning.
