Flexible Use of Limited Resources for Sequence Working Memory in Macaque Prefrontal Cortex

Nature Communications - How the brain represents and allocates limited working memory resources remains unclear. Here the authors show that the geometry of compositionality in macaque prefrontal...

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! 👇sciencedirect.com/science/ar…

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. Mental programming of spatial sequences in working memory in the macaque frontal cortex | Science science.org/doi/10.1126/scie…

Mental programming of spatial sequences in working memory in the macaque frontal cortex

How the brain mentally sorts a series of items in a specific order within working memory (WM) remains largely unknown. We investigated mental sorting using high-throughput electrophysiological...

How does the frontal cortex flexibly control sequence working memory? A new paper from the lab just out in NEURON. authors.elsevier.com/a/1jeMN… We found separable and generalizable subspaces for sensory & WM. The neural dynamics within these subspaces reflected the control of SWM.

Is Geometry a Language That Only Humans Know? (Published 2022)

Neuroscientists are exploring whether shapes like squares and rectangles — and our ability to recognize them — are part of what makes our species special.

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.

Our work on Working Memory for Spatial Sequences in human adults, children (6y), and macaque monkeys is published in the Journal of Neuroscience. This work is the result of great teamwork in the lab!! Also with Mariano Sigman and @StanDehaene jneurosci.org/content/42/5/8…
