Excited to be headed to my first @acnporg.bsky.social meeting! Stop by my talk to hear about D1-islands in the human NAc or my poster to hear about our efforts to use spatial transcriptomics to profile lateral septum neurons in the human brain.

Congrats Keri! So well deserved and looking forward to this next chapter at LIBD. 🎉

Top-down control of sustained attention by the medial prefrontal cortex (mPFC)- locus coeruleus (LC) circuit during the rodent continuous performance task (rCPT) The medial prefrontal cortex (mPFC) plays a pivotal role in attention by exerting top-down control to allocate cognitive resources toward behaviorally relevant stimuli based on learned context and exp...

Finally on Bluesky and I’m really excited to share this latest preprint with @jorge-miranda.bsky.social in which we functionally examined the role of a medial prefrontal cortex (mPFC)- Locus Coeruleus (LC) circuit in regulating sustained attention.

Congratulations to our habenula team! We've learned a lot about working in this tiny brain region. Here we characterize the molecular signatures of human habenula cell types and transcriptomic changes associated with schizophrenia. Stay tuned 👀 for more exciting habenula findings in the near future.

Here’s my Fluorescence Friday highlight: just got this beautiful shot from the locus coeruleus in our latest tissue section! You can see astrocytes (in green) glowing and wrapping around tiny blood vessels (in red), with pTau staining (in magenta) lighting up the scene. It’s wild how much is going on in just one microscopic field—so cool to see these markers all together and think about what they mean for brain health and Alzheimer’s research. Loving the chance to peek into these cellular hangouts each week! #FluorescenceFriday #PhDLife #Neuroscience
