My PhD project is out as a preprint!
We combined 2P and synchrotron X-ray to understand mouse olfactory bulb circuits, linking physiology to structure in 3 animals! doi.org/10.1101/2025.04.24.6…

Hi @SfNtweets,
Neurons of the same olfactory circuit in the mammalian brain share firing properties while showing individual traits.
More about it today PM, poster E37 (PSTR341.09).

Big news! The fly connectome is featured on the cover of a special edition of Nature.
This is all possible thanks to the collaboration of 292 members of The FlyWire Consortium!

Our new paper is out today in @Nature , showing that bumblebees possess the cognitive capacity for some of the key ingredients of cumulative culture, previously though to be unique to humans

📣 We're excited to announce the opening of multiple faculty positions!
Do you use and/or develop artificial intelligence methods and mechanistic mathematical models to address fundamental questions in biology?
We'd love to hear from you.
(Please share far and wide 🙏)

Scientists from @UW (@casa_tuthill ) with @APacureanu at ESRF have found how fruit flies 🪰sense leg movements.
Their research is published in @NeuroCellPress

How useful is a connectome? We show that you can predict quite a bit about the neural activity of a circuit from just measurements of its connectivity. Led by star graduate student @lappalainenjk, collaboration with @jakhmack. #connectome biorxiv.org/cgi/content/shor… 1/n
