Happy to share our preprint! We show that hypothalamic hunger-promoting AgRP neurons reflect proximity to food across different mazes in hungry mice. After mice discover food, AgRP activity decreases as they approach the food and increases as they move away.

We launched NISB to make #connectomics neuron segmentation progress measurable. 📈 First submission — straight to the top 🏆 Donglai Wei: 59.6% NERL vs our baseline's 43.0%. Congrats! 👏 ~40% of neuron length still unaccounted for. Rolling submissions 👉 structuralneurobiologylab.github.io/nisb/

1/11 Excited to share my postdoc work from @schierlab.bsky.social and Rainer Friedrich! 🐟👃 How does the brain decide whether an odor is good or bad? In larval zebrafish, we find that odor preference is reflected in spatially cohesive neuronal domains of the olfactory bulb. 🧵

🚨 New paper in @nature.com We asked why two hippocampal areas with very different anatomy, CA3 and CA1, often seem to code space so similarly? By recording bats flying up to 200m, we found that the difference was hidden by scale! www.nature.com/articles/s41... 🧵 1/11

Sparse-to-dense coding transformation between hippocampal areas CA3 and CA1 - Nature

The hippocampus exhibits a CA3-to-CA1 coding transformation that combines fast learning with an efficient, compressed neural code.

#SfN25 Monday morning we present FERAL: a video-understanding tool for animal behavior detection without the need for tracking or pose estimation! FERAL detects single animal, social and collective behavior in the lab and the wild! Visit our poster at board ZZ5 and check more here: www.getferal.ai

Let me introduce our new lab homepage. www.spatial-navigation.com We are looking for PhD students and one Postdoc that can start in November 2025. Contact me if you are in to studying spatial memory of honeybees. @uni-wuerzburg.de @neuroethology.org

Beetz Lab

Our group studies the neural mechanisms underlying spatial memory in insects. As central place foragers, honeybees begin their foraging trip at a fixed location, i.e., their nest. This site fidelity.....
