Arc mediates intercellular tau transmission via extracellular vesicles

Tau pathology spreads cell to cell, but the mechanisms of intercellular tau transmission remain unclear. We find that the neuronal gene Arc is critica…

Our preprint is out! www.biorxiv.org/content/10.1... Peter Skovorodnikov and I are excited to present FERAL: a new video-understanding toolkit that maps raw video directly to behavior, no pose estimation required. It works across species, from lab to field, and even in collective systems. (🧵1/n)

FERAL: A Video-Understanding System for Direct Video-to-Behavior Mapping

Animal behavior unfolds continuously in time, yet quantitative analyses often require segmenting it into discrete, interpretable states. Although manual annotation can achieve this, it remains slow, s...

🧠🌟🐭 Excited to share some of my postdoc work on the evolution of dexterity! We compared deer mice evolved in forest vs prairie habitats. We found that forest mice have: (1) more corticospinal neurons (CSNs) (2) better hand dexterity (3) more dexterous climbing, which is linked to CSN number🧵

People thought I was bonkers studying courtship and mating in Drosophila erecta nearly 50 years ago. Sometimes you just have to wait.

Excited to share our new #biorxivpreprint We discovered that the fruit fly #drosophila erecta requires food odor to mate and arousal is further enhanced by social group motion. Cross-species analysis of brain activity reveals a novel gate evolved from within a conserved circuit shorturl.at/gGYm7

If you’re interested in ants, olfaction, gene regulation, or all of the above, here’s a new preprint from the lab for you. It describes an unorthodox mechanism of transcriptional interference by which ant olfactory sensory neurons produce a single functional receptor. www.biorxiv.org/content/10.1...

Transcriptional Interference Gates Monogenic Odorant Receptor Expression in Ants

Communication is crucial to social life, and in ants, it is mediated primarily through olfaction. Ants have more odorant receptor (OR) genes than any other group of insects, generated through tandem d...
