Made an AI-curated primate ephys literature database covering ~10000 papers with recording brain regions and target functions. Maybe useful for something.

We’re launching Astera Neuro, a new neuroscience research effort led by @doristsao as Chief Scientist. Our aim is to unravel a profound scientific mystery: how the brain transforms sensory inputs into conscious experience.
Advancing this work could illuminate the computational principles that drive perception and cognition and inspire approaches for neuroscience-informed AI research, potentially generating new pathways to AGI.
Astera will support this work with $600M+ over the next decade. Read more: https://t.co/GIFPBRyrT0
Flexible Use of Limited Resources for Sequence Working Memory in Macaque Prefrontal Cortex
FYI: Understanding WM resources at both the single neuron and population levels.

Sequence WM gating through synchronization! We found frontal cortical theta-range spike-field coherence is rank-selectively associated with spiking-based memory subspaces, supporting the binding of items to their associated ordinal ranks.
Just online! 👇https://t.co/z2BU3Msf4h
It’s time to work WITH memory!
New work from our lab is out: Extra temporary subspace is necessary for information exchange or asynchronous programming.

How does the frontal cortex flexibly control sequence working memory? A new paper from the lab just out in NEURON. https://t.co/p6MP3HaWlD We found separable and generalizable subspaces for sensory & WM. The neural dynamics within these subspaces reflected the control of SWM.
Yesterday we delved deep into persistent activity: what it means for cognition and how it is mechanistically implemented, at a symposium honoring Joaquín Fuster. I especially liked the combination of theory & experimental talks. #UCLA#neuroscience

A thread (1/n)
A new paper from the lab:
We use behavior, fMRI and MEG to show that auditory sequences are compressed in working memory, using a recursive language essentially identical to the one that we use to encode geometric sequences

Geometry of sequence working memory in macaque prefrontal cortex
With such a talented team: Yang Xie, Peiyao Hu, Shiming Tang and Bin Min, also with Xiao-Jing Wang @xjwanglab, @yang_tianming and @StanDehaene. Thank you all!

Using two-photon calcium imaging of macaque DLPFC, we show that sequence working memory relied on a compositional neural code with separate disentangled low-dimensional rank subspaces for every rank. Stay tuned: there is more coming soon from our electrophysiological experiments.
