I agree, #neuroscience has officially moved. This will be my last tweet Please like and RT this to make sure everyone knows where to join us!
We did it. We killed neuro twitter and it's resuscitation it's happening somewhere else. Come join us! https://t.co/E4aEGyOlvf

Happy to share Anisia's work @AJPEndoMetab where we found that the adrenoceptor alpha-1b plays a key role in mediating the effects of the sympathetic nervous system on hepatic metabolism, particularly in female mice! https://t.co/8kA91Mn004

A promisiong way to reduce glial scars when using chronic electrode implantation. Results from a collaboration that was initiated a few years ago.

Glial scarring (GS) occurs due to the activation of astrocytes in response to a physical insult to the brain, such as the insertion of a neural implant. Here, a biophysical paradigm for inhibiting...

Excited to publish a broad set of enhancers to target interneuron types in the brain, along with a broad set of collaborators. This is part of the BI armamentarium, which together will help revolutionize the targeting and understanding of brain circuits. https://t.co/NWI7xHreB8
biorxiv.org
In recent years, we and others have identified a number of enhancers that, when incorporated into rAAV vectors, can restrict the transgene expression to particular neuronal populations. Yet, viral...

As a scientist, one of my absolute fav things to do is apply methods that we've developed to imaging datasets from the literature that we love to test our theories of how the brain is organised. Our newest paper in @CellReports led by @NatashaL_Taylor ticks all these boxes!

Extremely pleased to finally share Chao’s hard work developing and implementing a strategy to identify GPCR agonists that selectively modulate particular locus coeruleus (LC) projections. Rarely have I ever been so proud of a person or a paper, I sincerely hope you enjoy it too.

Excited to share our latest research published in @Nature! We explored how working memory representations evolve and stabilize with practice, using simultaneous volumetric imaging of more than 73,000 neurons. Big thanks to my amazing team and collaborators! Special appreciation
