Can a single brain cell decide whether to eat or not? ๐ง ๐ชฐ
Turns out... yes. And we found it in the fruit fly.
A pair of neurons called SELKs (subesophageal leucokinin neurons) can drive feeding behavior in both directions. They promote it or suppress it. Here's how: ๐งต

Fรฉlix Simon's paper is out in its final form ๐
When we got into (extreme) detail in the temporal and spatial patterning of neuroblasts, Fรฉlix asked a simple question "sure, but how does this translate into neuronal cell fate?". www.nature.com/articles/s41...
New @currentbiology.bsky.social paper from Dr. Leila Elabbady on neural circuits that transform a touch stimulus into spatially targeted grooming.
Leila discovered a leg somatotopic map and used it to infer tactile receptive fields in the fly VNC connectome.

New preprint with @sevberg.bsky.social! We map Hopfield-like binary networks onto spiking networks with dendrites โฆ and it works! Same memory capacity, bigger basins of attraction, plus selective recall through dendritic gating, and more. How? Dendrites! See below.
Are you a computational scientist? Within 7 years of your PhD? Come join us at Lund University! We have two new positions as assistant professor! Deadline: 25th of May. The advert is broad, but this is your chance to push computational neuroscience in a fantastic place!

How spontaneous is spontaneous behavior? ๐ง ๐ญ
We found that whole-brain fUSi signals predicted spontaneous behavioral transitions seconds in advance. Inhibiting one node of this transition-prone state, the medial septum, facilitated switching!

Graphical abstract showing that NMDAR immunisation drives psychosis-like behaviour in mice, while clozapine reverses this. Upper panel: arrows show NMDAR immunisation producing a mouse exhibiting psychosis-like behaviour, with clozapine reversing this effect. Lower panels: anti-NMDAR antibodies bind neuronal NMDA receptors, which are then eliminated by microglia via phagocytosis, leading to psychosis. Clozapine restores NMDA receptor levels by reducing anti-NMDAR antibody levels, consistent with an immunomodulatory mechanism of action.

How does an animal choose between exploring for a better food source and taking advantage of a known one? Our recent work in Current Biology demonstrates how recent feeding and metabolic state dynamically influence fly local search. bit.ly/3PfrIv3 #Science #Neurosky #Foraging #Drosophila

Paper out now in eLife: DANCE. We combine machine learning with accessible hardware to quantify Drosophila social behaviors.
Low-cost behavioral rigs are not a compromise, they are a design philosophy. Accessibility changes the questions we can ask.

Several fly larvae are crawling on an agar surface.
The second paper from the lab is now available on bioRxiv: www.biorxiv.org/content/10.6...
We discovered that cannibalistic behavior in fly larvae is social-context dependent. Larval groups avoid dead conspecifics; individuals show high attraction. They only do it when no one is watching ๐
