How do brains rewire throughout life?
Our paper out in @Nature today outlines several principles of brain circuit development that we found by mapping the complete wiring of eight brains.

Our paper on flexibility in the cellular encoding of sexual state in C. elegans is out today! Great work from @TheScientistHan, @LeighWexler (former @portmanlab graduate students) and Hayley Wnuk (current graduate student). Here’s a synopsis. #celegans cell.com/current-biolog… 1/
First: this is a story about biological sex, not gender. The latter is socially and culturally influenced and is deeply tied to self-identity. Humans have this; worms don’t. 2/
Biological sex is typically seen as a static, binary characteristic. It’s not hard to see why — most species have two distinct morphs that produce different types of gametes, and this state is often set by a binary sex-determining cue (e.g., sex chromosomes). 3/
How does the brain coordinate animal behavior across timescales?
@salazarori and I address this question in our latest from @Zimmer_Lab: “Nested neuronal dynamics orchestrate a behavioral hierarchy across timescales”

@salazarori @Zimmer_Lab @NeuroCellPress In a behavioral hierarchy, as proposed by Tinbergen, long-timescale behaviors are composed of shorter-timescale ones. For example, the stickleback’s reproductive instinct (Hierarchy Level 1) includes mating and fighting (Level 2); each in turn consists of several sub-actions. 2/
@salazarori @Zimmer_Lab @NeuroCellPress Many behaviors can be described this way (e.g. recent work by @gordonberman @aexbrown @daniobrain), but are the underlying neuronal mechanisms actually hierarchical? 3/
