Excited to post a new preprint, work by @T___Kawashima, @zq_wei and collaborators: Voltage imaging reveals circuit computations in the raphe underlying serotonin-mediated motor vigor learning https://t.co/IHzsx0z4AF
biorxiv.org
As animals adapt to new situations, neuromodulation is a potent way to alter behavior, yet mechanisms by which neuromodulatory nuclei compute during behavior are underexplored. The serotonergic raphe...

This was such a fun animation to make! Very happy for Mike, @malcgcamp @naoshigeuchida et al to see their work now out on @biorxiv
Excited to share our updated preprint on the neural basis of foraging decisions! This work was co-led by Michael Bukwich (twitterless, now at UCL) and me, with major contributions from co-authors, and the incredible animation is by @KJHerr23. (1/12) https://t.co/GopGdBoVly

I’m very excited to share that my graduate work is now online in @ScienceMagazine today! With generous help from my mentor @yuji_ikegaya and my amazing teammates, we investigated a top-down pathway for volitional heart rate regulation! https://t.co/AoYwZ4J1Z0
science.org
Heart rate (HR) can be voluntarily regulated when individuals receive real-time feedback. In a rat model of HR biofeedback, the neocortex and medial forebrain bundle were stimulated as feedback and...

Mood-altering compounds hold promise for the treatment of many psychiatric disorders, such as depression, but connecting their molecular, circuit, and behavioral effects has been challenging. Here we...
We are very excited to share our work using #zebrafish to study fast acting antidepressants work! Tl;dr –ketamine and related drugs drive minutes-long calcium elevations in astroglia sufficient to mediate their effects. https://t.co/1XIqOcIQqG Details below:
