I’m excited to share a new paper from the lab. The study led by Xiaowei Gu reveals how the mPFC encodes complex emotional memories, using an internal model to infer emotional associations and memories via projections to the amygdala. a🧵(1/8)

Prefrontal encoding of an internal model for emotional inference
Nature - Neurons in the rodent dorsomedial prefrontal cortex encode a flexible internal model of emotion by linking directly experienced and inferred associations with aversive experiences.

A fascinating paper from Hokto Kazama's lab draws upon the fly connectome and large scale recordings to show how olfactory valence is encoded in distinct neurons in the lateral horn (drosophila amygdala) through labeled lines and biased feedforward inhibition www.sciencedirect.com/science/arti...
Distinct circuit motifs evaluate opposing innate values of odors
Evaluating the innate value of objects is critical for expressing adaptive behaviors. However, where and how this computation takes place in the brain…

Excited to announce that I'll be moving to the Univ of California Irvine @ucirvine.bsky.social next Spring!🌴

Happily, this is not goodbye to Japan as I'll continue my lab @RIKEN_CBS for some time.

Help spread the word: the new UCI lab will be hiring, DM or email ([email protected]) if interested!

A spatially resolved transcriptomic atlas of the primate amygdala (human, macaque, and baboon) now out in Science Advances (www.science.org/doi/10.1126/...). The amygdala contains 32 types of neurons with many neuron types specific to particular subdivisions.

Lots of updates from the preprint!
Transcriptomic diversity of amygdalar subdivisions across humans and nonhuman primates
Specialized cell types and links to psychiatric disorders are revealed by genetic mapping of primate amygdala neurons.

Excited to share our latest paper - now out in @science.org - we showed how oxytocin modulates maternally-directed behavior in young mice (P15).

Please RP.
We are thrilled to announce that our lab’s first preprint is out!
”Whole-genome single-cell multimodal history tracing to reveal cell identity transition”

We report HisTrac-seq, a multiomic single-cell molecular recording platform.
