1/8 Breathing seems automatic. But it's a finely tuned motor behavior that has to be controlled. In this preprint, I map the circuits that match a fly's respiration to the metabolic demands of flight and mitigate the risk of dehydration. 🧵🪰 www.biorxiv.org/content/10.6...

Finally out in @natneuro.nature.com! A forgotten memory isn't always gone. We show that forgotten memories persist as silent memory traces, can be recovered by reminders, and can even be reconstructed into false memories. Excited to finally share this work! www.nature.com/articles/s41...

The origin story of eukaryotes has more plot twists than a Hollywood blockbuster! 🧵 Read more in my new review: doi.org/10.1146/annu.... Only in the 1960s were the terms "prokaryote" and "eukaryote" formalized! As originally defined, eukaryotes had complex architectures, prokaryotes did not.

How can a single cell learn without a brain? We explore this in my paper with @wallaceucsf.bsky.social! We discovered that single cells may learn using molecules similar to those that animal brains use to learn, like CaMKII. Cells can also propagate memory states to their progeny!

Fresh results now in bioRxiv! 🎉 We know about the function of NREM sleep for overnight memory consolidation. But what about REM sleep? We found that in aging, slow delta waves can intrude phasic REM periods, and this, is associated with worse overnight consolidation 🧠 (1/5) doi.org/10.1101/2025...
