- Our first preprint has been accepted for publication www.science.org/doi/10.1126/... !! tldr: @ezeyulu00.bsky.social , @amartyapradhan.bsky.social , @dkoveal.bsky.social and I developed a method using injectable nanoparticles to turn mice into…constellations in motion. 🧵⤵️
- If we want to understand movement, we have to track it. In people, we can look like Andy Serkis and wear a Styrofoam ball bedazzled swimsuit.
- Unlike Mr. Serkis, mice don’t like the suit, and they don’t like anything being attached to their skin. And even if you did manage to get something onto/into the skin, they have lots of fatty tissue, which makes their gelatinous bodies hard to track from the “outside-in”.

- Reposted by Jeff MarkowitzVery honored to be awarded tenure officially this week. SO grateful to my amazing lab, and to mentors, sponsors, and friends who played an absolutely essential part in this.
- Reposted by Jeff MarkowitzOur latest! We measure dopamine signals as rats disambiguate cues that predict reward or threat. We find that dopamine flexibly tracks the changing salience and value of cues, but according to region-specific scales, rapid within-trial dopamine fluctuations prioritize different stimulus features.

- Reposted by Jeff MarkowitzThe final #InterfaceNeuroGT session covered joint modeling of brain and behavior. Speakers highlighted how they're using innovative computational and experimental approaches to understand how neural activity influences behavior and intention. Chaired by @vulcnethologist.bsky.social.
- Reposted by Jeff MarkowitzMaps are everywhere in the brain...and finally we've discovered one in the nose! Led by @davidhbrann.bsky.social, we uncovered the logic that specifies the positions of each of the 1,000 sensory neuron subtypes in the nose and aligns their projections to the brain.👇👃see more details below👃👇
- Reposted by Jeff MarkowitzInterfaceNeuro was a great meeting! There is such an impressive range of technologies being developed for neuromodulation and brain-computer interfaces. It was nice to see this work presented alongside more basic science efforts to figure out exactly what/where we should be modulating.

- Wrote a review with some thoughts about dopamine's role in movement. Hope people find it useful and/or stimulating! Thanks again to @bensaunders.bsky.social for the invitation and editing this issue. kwnsfk27.r.eu-west-1.awstrack.me/L0/https:%2F...
