Online now: Attenuated hypothalamic response to fructose via a dedicated gut-brain pathway dlvr.it/TSz9JP
New lab paper @NeuroCellPress!
@_Aaron_McKnight asked a simple question:
Do calories look the same to hunger neurons in the brain? The answer is no.
Fructose and glucose contain the same calories, but they engage fundamentally different gut-brain pathways.
doi.org/10.1016/j.neuron.202…
Thank you to the team, including @_Aaron_McKnight, @alanaraujo87, @_alexvtheg, @GdeLartigue, and our other co-authors!

Can we predict what a molecule smells like from its structure? A new exchange in @ChemSenses debates this question. @KingFunk5000 @emilyjmayhew

I’ve been hosting the 7th International Melanocortin Meeting here in Cambridge with my co-organisers Roger Cone, Kate Ellacott and Anne White. Spectacular science! Here we are at the conference dinner! #obesityisnotachoice

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. biorxiv.org/content/10.1101/…

The one and only @AmberAlhadeff visited @UBuffalo and gave a great talk about the power of hunger in the @UBNeurosci seminar series. #SSIBlingInTheWild @SSIBsociety @ub_cibr

🚨 Exciting New Research Alert! 🚨 Our latest study, published in #NatureMetabolism, reveals how memory circuits in the brain drive intake of fats and sugars and impact body weight. 🍫🍟 Let’s break it down! 🧵

Very good, concise summary of the gut-brain axis of communication and interoception

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

HAPPY to share our new paper! Are there specific neurons for food need (hunger) and food motivation (appetite)? Computational modeling and neural activity recording dissociated these two neurons.THX to @HyungGoo_Kim @kyusik_kim_ @SerenaYounghee @bbbining science.org/doi/10.1126/scia… – at Songpa-gu, Republic of Korea

Monell Chemical Senses Center. These are the people who truly understand my deepest questions. This is the reason I chose the life of a scientist, to chat forever about nerdy things and making special friends. @AmberAlhadeff @GdeLartigue @dietrich_mo – at Philadelphia, PA

Be mindful about axon collateralization! We have changed some experimental strategies based on this discovery. Proud to have the cover image for this journal issue and also a “Featured Article” designation! Happy times.

Specific neurons in the brain’s zona incerta play a crucial role in the early social interactions of an infant and its mother, building their bond and reducing stress, according to a new Science study in mice.

So happy to share our new work that is now out @sciencemagazine: We show how neurons in the mouse zona incerta (ZI) modulate infant social behaviors and learning. This work was led by the AMAZING graduate student Yuexuan Li @yuexuan_li. 🎉science.org/doi/epdf/10.1126… #ScienceResearch

#NatMetabPicks | In @Nature led by @AmberAlhadeff (@Penn):
The neural circuits in the hindbrain linking satiety and aversion are shown to be separate, raising the possibility of developing #obesity drugs without the side effects of nausea and vomiting.
