Axonal defasciculation is restricted to specific branching points during regeneration of the lateral line nerve in zebrafish

Delighted to share this piece of my PhD work:
Astrocytes and neurons exhibit partially shared but distinct composite receptive fields for natural stimuli. We show that astrocytes have distinct receptive fields and suggest that they play a complimentary and distinct role in sensory processing.

Some of the work I did for my PhD finally on biorxiv! We study calcium responses of astrocytes and neurons in vivo in response to ultrasonic vocalisations

Researchers keep a mammalian cochlea alive outside the body for the first time - News The technological breakthrough may improve our understanding of the cellular mechanisms behind hearing loss.

Shortly before his death last month, James Hudspeth and his team achieved a groundbreaking technological advancement: the ability to keep a tiny sliver of the cochlea alive and functional outside of the body for the first time. #RockefellerScience

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...

Ants 🐜 coordinate their societies through smell 👃. They carry more odorant receptor genes than any other insect 🧬, yet each olfactory neuron must somehow select and express just one.

My brilliant former student Giacomo Glotzer and colleagues have discovered how:

It has been a great privilege to have worked with Jim. A truly inspiring individual who embodied a level of kindness, curiosity, and wisdom we should all aspire to.

Amplification through local critical behavior in the mammalian cochlea | PNAS Hearing hinges upon the ear’s ability to enhance its responsiveness by means of an energy-expending active process that amplifies the very mechanic...

We took the #ear ’s in-built amplifier out of the body, watched it work live, and saw that it runs near a state of #criticality, a knife-edge balance that lets us hear from whispers to thunderclaps and up to 20 kHz. Birds, reptiles, and insects exploit the same physics. #Biophysics shorturl.at/AkMz9

Remember seeing his talk in Kyoto last year, very cool stuff! Congrats!

Super proud of both Johnny and John, they demonstrate a generative model for synthesising natural mouse vocalisations and show that these artificially generated vocalisations can be used to probe receptive field properties of neurons in real mice!
