New preprint up! By confining anterograde tracer injections to discrete areas of the lateral hypothalamus and zona incerta, we detail the unique patterns of efferent projections throughout the brain, especially to regions involved in fear and defensive behaviour. @dr-cjp.bsky.social

Here's a report from Jenny Sinclair @jsresearchpro.bsky.social on the low success rate for DECRAs this week, driven by high demand and low Government funding for early career researchers in Australia. [Free article in @resprofnews.bsky.social]

One of my figures from mine and Christina’s (@dr-cjp.bsky.social) recent paper was chosen for the cover of this month’s issue of Journal of Neurochemistry! 🧠 You can check out the summary here doi.org/10.1111/jnc.... Glad to see those pretty zona incerta neurons seeing the spotlight!! ☺️

Relaxin family peptide receptor 3 (RXFP3) expressing cells in the zona incerta/lateral hypothalamus augment behavioural arousal
Relaxin family peptide receptor 3 (RXFP3) is an inhibitory G-protein coupled receptor expressed widely throughout the mammalian brain. We show that RXFP3-expressing cells in the mouse zona incerta an...

Very excited about this! It’ll be my first Pavlovian Society meeting, and I happen to know that Mel had scored an excellent spot to hold it!
