Yet another cool story just came out of the ever-so-capable hands of Roy Harpaz (@royharpaz.bsky.social). www.nature.com/articles/s41... Roy showed that larval zebrafish will adapt and get used to crowded conditions, and that they are then, later on, less sensitive about their personal space.

My PhD paper is out in Science Advances! We found that the adult zebrafish cerebellum encodes both positive and negative valence during GO/NOGO task learning, and teaching signals sent to Purkinje cell update internal models of task rules. www.science.org/doi/10.1126/...

The cerebellum implements structured representation of valence to support adaptive behavior control

Cerebellar circuits identify danger and safety to guide flexible, adaptive behavior.

New method for identifying the fine transcriptomic types of thousands of neurons recorded in vivo!

New preprint from the lab, led by Bradley Cutler. With the @james-gagnon.bsky.social lab we use zebrafish to show that fever is not a reduction in the perception of warmth. Immune signals instead increase the valence of warming stimuli while cooling turns aversive. www.biorxiv.org/content/10.6...

Using light-activated CRISPR in zebrafish, we triggered synchronized DNA breaks and track the repair process. ⚡🐟⚡

What has changed in mama bear brain (well, actually mice) to make her risk her life to attack a potential threat and protect her young? Oxytocin is the key! Happy to share our new study led by two awesome postdocs: Takashi Yamaguchi and Rongzhen Yan. www.nature.com/articles/s41...

In mice, female aggression is governed by an amygdala–to–medial hypothalamus circuit that is strengthened during pregnancy and is dynamically amplified by oxytocin during lactation.
