I've been waiting some years to make this joke and now it’s real:
I conned somebody into giving me a faculty job!
I’m starting as a W1 Tenure-Track Professor at Goethe University Frankfurt in a week (lol), in the Faculty of CS and Math
and I'm recruiting PhD students 🤗

The spot of a past lab member usually gets scavenged by other members rather quickly, on a first-come, first-served basis. This time, I'm separating my most valuable possessions and making a raffle so that the other lab members have equal opportunities in the scavenging

Stoked to see this paper finally out!
It answers two big questions: where visual objects are encoded in the brain, and how head-direction cells get oriented using visual landmarks.
Super fun collaboration with @mace-lab.bsky.social and Stuart Trenholm.

We found a preference for visual objects in the mouse spatial navigation system where they dynamically refine head-direction coding. In short, objects boost our inner compass! 🧭

Gero's talk at the last SFN about this has been the most mind-blowing seminar in neuroscience I've seen.
Sleep might be an “inescapable consequence” of aerobic metabolism, new findings in fruit flies suggest.

Mitochondria set ‘ancient’ metabolic thermostat for sleep in flies, separate from circadian rhythms
During waking hours, a specialized set of sleep neurons in the fly brain accumulates reactive oxygen species, which eventually trigger sleep to clean up and repair the damage they do.

I previously noticed that to decode body movements from V1 superficial layers required much more neurons (>600) than my recordings of deep layers (~200). It's great to see a head-to-head comparison
A new study led by @timothysit.bsky.social reveals that different layers of mouse V1 integrate visual and non-visual signals differently.
Activity is dominated by vision (or spontaneous fluctuations) in L2/3 and by movement in L5. This leads to different geometries.

Can the brain reverse its dynamic flow? Batista/Yu’s lab shows that neural activity follows strict temporal constraints. Monkeys using a BCI could not reverse neural trajectories, suggesting that the brain’s intrinsic dynamics enforce a structured flow of activity. doi.org/10.1038/s41593-024-01845-7

Oby, Degenhart, Grigsby and colleagues used a brain–computer interface to challenge monkeys to override their natural time courses of neural activity. They found the time courses to be highly robust,…
