hi all - happy to present new work from my laboratory now published in Current Biology - posterior parietal cortex is home to different sub-populations mapping action series versus cross-path structural similarities - congrats to alex johnson and emily xu!

Awesome work by Tudor. This is a fun story that started with a fairly unsurprising observation - that motor cortical activity dissipates rapidly after a CPG-driven movement is initiated. The explanation for why is quite surprising though and begets a bunch of interesting new questions.

AOC: This has now become what we feared most about ICE for a long time—that it would be used as an anti-civilian force with no accountability. At the end of the day, what we saw today was a murder, and murders in cold blood need to be prosecuted.

Any other UC folks encountering extensive red tape when purchasing from IMEC? UCSB says a clause in the purchase agreement requires a special exception from UCOP - is that the case for others? It's been almost 2.5 months since we began an order for more probes and we are still stuck at the uni...

New preprint from the lab!
A frontal motor circuit for economic decisions and actions:
www.biorxiv.org/content/10.6...

We use a novel task in mice, cortex-wide imaging and optogenetics, NPX recording and modelling to reveal a circuit mechanism that transforms abstract decisions to spatial actions.
A frontal motor circuit for economic decisions and actions
Flexible behaviour requires transforming abstract cognitive representations, such as value preferences, into concrete motor actions. During economic decision-making, individuals evaluate options to gu...

Keinath lab already absolutely killing it (as expected)
Excited to share the first peer-reviewed work from the lab (what a moment)! We have two papers to share. First, some work on heading integration in humans.

Another new paper from the lab: Predictive theories like the SR imply that navigators who navigate differently should have cognitive maps which differ in predictable ways. Here we show that this holds in mouse hippocampal CA1.

Environmental representations in mouse hippocampal CA1 reflect the predictive structure of navigation
Predictive theories of cognitive mapping propose that these representations encode the predictive relationships among contents as experienced by the n…

Had a really nice visit to UCSB, learning about the awesome neuroscience research there and presenting our work on voltage imaging in the molecular cellular and developmental biology seminar series.

Thanks to my host Ikuko Smith, who might have the best office view in all of UC!

🧠📢 New preprint alert

Large-scale ephys is exploding but spike sorting remains the computational bottleneck. A 2-hr, 6-probe Neuropixels 2.0 Quad Base session can take over a week to sort on a single machine. Here's a better solution. 🧵
