New paper out in @pnas.org Thalamic CGRP neurons form a spinothalamic pain pathway relaying pain signal to the amygdala & insular, but not sensory cortex to encode the affective dimension of pain. Huge congrats to first author Sukjae Kang & coauthors. www.pnas.org/doi/10.1073/...

Lots of recent papers discuss the nucleus of the solitary tract in interoception. In this review, we take a sensory processing perspective on how interoceptive signals are encoded in the NTS:

Congrats Greg and team!🎉🎊🎊

Amazing story! Congratulations, Greg and team!!!🎉🎊

Convergent state-control of endogenous opioid analgesia

We uncover how cognitive + contextual factors—like injury, fear, and placebo—modulate pain through dynamic opioid signaling in the periaqueductal gray (PAG)

A study in Nature Neuroscience identifies a prefrontal–pontomedullary pathway that slows breathing and reduces anxiety in mice. The findings explain a circuit basis for top-down control of breathing, which can influence emotional states. �Ÿ”’ https://go.nature.com/3CUtPy3

"Frequency-dependent transmitter switching" adds a new layer of complexity to neurotransmission, potentially uncovering how individual multi-transmitter neurons encode diverse information. Firing rate must be recognized as a crucial variable in optogenetics, as previously highlighted!

Some glutamatergic synapses show decreased release probability (Pr) at high firing rates due to vesicle depletion or VGCC feedback inhibition. In contrast, neuromodulator vesicles exhibit increased Pr, enabling frequency-dependent encoding of distinct information via transmitter switching.

Thank you for your kind words! I am very glad that you enjoyed reading it.

Thanks a lot!

Thank you, Tom!!!

Excited to share my first post here! Our new paper reveals a top-down breathing circuit that slows breathing to ease anxiety & fear. A step forward in understanding how brain-breathing interactions shape emotion. Published in Nature Neuroscience—grateful to my team!

An empirical finding providing a glimpse into why meditation or breathing practices could work for reducing negative affect! An amazing paper by Sung Han’s team at Salk Institute🧘‍♀️🧘‍♂️👏🏽https://www.nature.com/articles/s41593-024-01799-w
