Minel Arinel

one last PhD poster in the city where my next adventure starts… see you soon SD 🌊💙 #SfN25 @sfn.org

Thank youu!!!

Thank you!! 🥳

Wonderful news! Congrats, Dr. Arinel 🎉 #PhDone

I’m officially Dr. Minel Arinel!! Grateful for every person who got me here, family, friends, mentors, and the zebrafish who made it all possible 🐟✨

Thank you!

Thank you!! By the power of the fish, I shall defend this doctorate 🐟🎓💪

I'm excited (and a little emotional) to be giving my PhD dissertation seminar as I wrap up my time in the Duke Neurobiology program 🧠🐟

📅 Monday, Nov 10 at 12:00 PM Eastern Time
📍 Bryan Research Building, Room 103

If you'd like to attend virtually, please feel free to DM me for the Zoom link! ✨

Just found out I received the @sfn.org #TPDA Trainee Professional Development Award FOR THE SECOND TIME!! 🧠🎉 Grateful for the continued support and excited to connect with the neuroscience community at #SfN25!

Thank youu!!

oh wow 🥹 @hhmijanelia.bsky.social

@natrevneuro.nature.com just published a beautiful cover for the issue that includes the recent review on analogies in the visual system of vertebrates and invertebrates (@ryosuketanaka.bsky.social). Read it here doi.org/10.1038/s415...

Frontiers | The gut and heart’s role in reward processing Reward processing, which ensures survival, has evolved to also shape emotions, learning, and overall well-being. While traditional models of reward have focu...

✨ New publication! ✨

Our mini-review on the #gut-brain and #heart-brain axes in #reward processing is out in Frontiers in Integrative Neuroscience! 🧠

We dig into how body-to-brain signals shape emotion and motivation and why it matters for mental health.

Compound found in common herbs inspires potential anti-inflammatory drug for Alzheimer’s disease

Scripps Research scientists have created a diAcCA, a stabilized form of carnosic acid—an antioxidant in rosemary and sage—potentially improving memory, fortifying neuronal connections & reducing brain inflammation— a promising therapeutic for Alzheimer’s.

Dual neuromodulatory dynamics underlie birdsong learning - Nature Dopamine release in the basal ganglia of the zebra finch is driven by neurons associated with reinforcement learning and by cholinergic signalling, and tracks performance quality during long-term lear...

Proud to have contributed to @jiaxuanqi.bsky.social's masterpiece out @nature.com! She shows that dopamine transients track the learned quality of song during juvenile learning and that dopamine release is driven not just by VTA firing, but by a local cholinergic mechanism! (1/x)

Super excited to share that my abstract got selected for a short talk at the @keystonesymposia.bsky.social on Interoception! Can't wait to visit Seattle and the @alleninstitute.bsky.social for the first time! #KSInteroception25

A genome-based phylogeny for Mollusca is concordant with fossils and morphology Extreme morphological disparity within Mollusca has long confounded efforts to reconstruct a stable backbone phylogeny for the phylum. Familiar molluscan groups—gastropods, bivalves, and cephalopods—e...

From octopuses to snails, the complicated molluscan family tree has now been mapped in unprecedented detail, researchers report in Science.

This includes sequences for 13 new complete genomes from across the phylum. scim.ag/3DrGAkg

Thalamic opioids from POMC satiety neurons switch on sugar appetite High sugar–containing foods are readily consumed, even after meals and beyond fullness sensation (e.g., as desserts). Although reward-driven processing of palatable foods can promote overeating, the n...

🧠🍽️ Satiety neurons that make you crave sugar? 🍬 New research shows that POMC neurons, typically linked to appetite suppression, release opioids in the thalamus, flipping the switch to increase sugar intake.

#neuroskyence 🧪 #appetite

Loggerhead turtles have an uncontrollable urge to dance whenever they anticipate food—a trait scientists used to test whether the reptiles can memorize their favorite feeding sites based on Earth’s magnetic fields.
