Congratulations Minel Arinel @minelarinel.bsky.social and the Naumann lab at Duke for this epic work on development of gut-brain communication!

Minel Arinel, Ph.D.@minelarinel.bsky.social · 2mo ago

My PhD paper (and my first research article👀) is out in @cp-iscience.bsky.social!🎉 Is gut-brain communication present in early development, and if so, how are these signals encoded in the brain? We tackled this question using larval zebrafish 🐟 www.cell.com/iscience/ful...

What a fantastic visit I had. Thanks so much @martinowk.bsky.social for hosting me and excited for future collaborations!

Was stoked to host @debbysilver.bsky.social at @lieberinstitute.bsky.social today! Fantastic talk on her lab's work on molecular features that make the human 🧠 unique and how RNA localization shapes early neurodevelopment. Great conversations + exciting ideas for future collaborations - thx Debby!

Very excited about this landmark study led by Drew Schreiner @schreinerdrew.bsky.social along with DIBS faculty network members John Pearson @jmxpearson.bsky.social and Rich Mooney! Opto & chemogenetic exploration of birdsong circuits guided by a computational framework. 🤩 Congratulations!

Where, exactly, does learning happen in the brain? Out today in @nature.com, we identify a synaptic locus of birdsong learning and show that the circuit can be tuned to make birds learn faster - but at a cost. Read on👇 #neuroskyence 🧪 #prattle 💬 #bioacoustics Shareable link: rdcu.be/fiyrS

New lab paper! 🧠 Human hippocampal & MTL theta activity is linked to eye movements, but only during memory-guided navigation. Theta is also strongest during longer, more exploratory eye movements. plos.io/4dwJhR8 Huge congrats to Humza & team! 👏

Eye movements reflect memory-related theta activity in the human brain

Theta oscillations in the medial temporal lobe support memory, but how they relate to eye and body movements during human navigation is unclear. This study shows that theta power increases during sacc...

How do MTL theta oscillations relate to eye & body movements during navigation? @suthanalab.bsky.social &co show that #theta power increases during #saccades under memory demands, linking exploratory gaze & planning to memory‑related dynamics during #navigation @plosbiology.org 🧪 plos.io/4dwJhR8

Experimental design and task. Top left: Intracranial electroencephalographic activity, eye and body movements were recorded as participants freely walked around the room. Wall-mounted motion-tracking cameras recorded the position of on-body reflective markers. Participants also wore an eye-tracking headset to monitor saccadic eye movements. A snapshot from the eye-facing camera is shown in the bottom right. For illustrative purposes, an experimenter is shown wearing the full setup. Top right: MRI of an example participant with an implanted RNS System. Purple dots indicate the location of four electrode contacts in the left medial temporal lobe (MTL). The top left inset shows an X-ray used to localize electrode positions. Bottom left: The environment contained 20 visible wall-mounted signs and three invisible circular target locations (0.7 m diameter). At the start of the task, participants freely explored the room to locate the invisible targets; each time a target was reached, an auditory tone signaled success, allowing them to gradually learn and remember these locations through experience. The task then alternated between two conditions: “visually-cued” navigation, during which participants navigated to a wall-mounted sign (e.g., “Blue 3”), and “memory-cued” navigation, during which they recalled and navigated to the previously learned invisible targets (e.g., “T”).

Another reminder as we've crossed into the second half of February. There's still time to apply for the Neurobiology Chair position at Duke University! Just send in a letter of interest and CV by Feb 28. Love of Duke basketball is not required.

The search for a new Chair of Duke Neurobiology is kicking off! Ad below. I've lived all over the country, but I'm glad I put my roots down here. Great people, great school, great area to live. Feel free to DM with any questions.

The biggest problem holding neuroscience back right now isn’t data or tools, thanks in large part to the BRAIN Initiative. It’s fragmentation across species. I wrote this to hopefully spark discussion around an issue that can only be solved as a community👇 www.thetransmitter.org/animal-model...

Neuroscience has a species problem

If neuroscience is serious about building general principles of brain function, cross-species dialogue must become a core organizing principle.

Last week, Jim Zhang (4th year PhD student, @DukeBrain ) presented Sina Tafazoli’s paper on building compositional tasks with shared neural subspaces. This 🧵 explores our thoughts (🤍 & ❔)
