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 rdcu.be/el19t nature.com/articles/s4158…

New paper alert! 🚨 In this study we explored how interactions between the locus coeruleus (LC), basolateral amygdala (BLA), and the ventromedial prefrontal cortex (vmPFC) affect freezing behavior and extinction learning. 🧵(1/5) pnas.org/doi/10.1073/pn…

Our live tissue clearing paper is out in @naturemethods! We achieved optical clearing of mammalian brain tissues without compromising normal neuronal function. Big congrats to @Shigenori774 and our wonderful collaborators! 🎉 nature.com/articles/s4159… (1/10)

How does the brain build a memory? A common assumption is that the neurons activated during an experience collectively form the memory engram. In our new Nature Neuroscience paper (finally out!), we show that this is not the case. nature.com/articles/s4159…

Excited to share our new paper: We uncover an LC→amygdala circuit linking β-adrenergic signaling to transcription regulation in defined amygdala neurons during reconsolidation—plus stress/elevated noradrenergic signaling at recall can strengthen memory. cell.com/neuron/abstrac…

The biggest problem holding neuroscience back right now isn’t data or tools, thanks in large part to the BRAIN Initiative. It’s fragmentation across species. I wrote👇 to hopefully spark discussion around an issue that can only be solved as a community thetransmitter.org/animal-models/…

New paper out! Looks the same. Connects differently Awake vs NREM activity barely changes, but topology does. Wide-field 2P imaging reveals that single-cell networks in unconscious states become more segregated while modules remain spatially intermixed. 👉 doi.org/10.1016/j.celr…

New paper from @YKNeuroRes in our lab 📢 We show body size predicts defensive behavioral strategy; smaller animals adopt active avoidance, larger ones favor freezing, while sex and age don’t drive the effect. A clear demonstration that traits matter. sciencedirect.com/science/articl…

Just out! “The astrocytic ensemble acts as a multiday trace to stabilize memory.” We identified astrocytic ensembles that link experiences across days to stabilize memory nature.com/articles/s4158…. New astrocyte tools are openly available at Addgene: addgene.org/Jun_Nagai/. 1/8
