Excited to share our new paper: We uncover a locus coeruleus→amygdala circuit linking β-adrenergic signaling to transcription regulation in defined amygdala cells during memory reconsolidation—+ stress or elevated noradrenergic signaling at recall can strengthen memory.

A neuromodulatory circuit-to-molecular pathway for reformatting aversive memories during recall
Tan et al. identify a neuromodulatory circuit-to-molecular pathway in rats that updates aversive memories when they are recalled. Noradrenaline from the locus coeruleus triggers synapse-to-nuclear tra...

A major part of our future health & prosperity lies in medical research. There are billions of available dollars that can be used for vital medical science. Please join the campaign for our government to act urgently to fully disperse these funds:

Most researchers miss out on innovation grants while medical fund sits on $25b
Nine in 10 Australian researchers had their “ideas grant” applications rejected last year, even as Australia’s medical investment fund sits on $5 billion more than it was designed to hold.

🎇 Excited to finally share JL Romero Sosa’s publication! Results are from single-cell imaging in different subregions of rat frontal cortex during ✨de novo learning. Spoiler: everything is not everywhere all at once

Neural coding of choice and outcome are modulated by uncertainty in orbitofrontal but not secondary motor cortex - Nature Communications
Neural mechanisms underlying flexible learning and decision-making are not fully understood. Using single-cell calcium imaging, authors here found that neurons in orbitofrontal and secondary motor cortex exhibit complementary roles in reward learning, with neurons in the former exerting a sustained role in conditions of uncertainty.

Have been away from social media, which has been nice. But figure I really should post some updates about what the lab has been up to. Posts incoming.
