Excited to share my work with @EngelTatiana, out now in @NatNeuro! We show that RNNs use low-dimensional latent circuit mechanisms for cognitive tasks. We find that context-dependent decisions in both RNNs and PFC arise from latent inhibitory mechanisms. nature.com/articles/s4159…

We are excited to present a Brain-Wide Map of neural activity during a complex decision-making behavior, a product of the monumental effort of 22 labs: 547 Neuropixels recordings in 267 brain regions from 115 mice collected in 11 labs 🐭 (1/8) biorxiv.org/content/10.110…

Thrilled to share our paper "Intrinsic timescales in the visual cortex change with selective attention and reflect spatial connectivity" now out @NatureComms! nature.com/articles/s4146… We added interesting new analyses to our preprint version (thanks to the reviewers!) #tweeprint👇

Excited to share our recent work on how selective attention modulates intrinsic timescales of local spiking activity in visual cortex and its underlying network mechanisms biorxiv.org/content/10.110… #tweeprint + some background on intrinsic timescales👇

Excited to share our new preprint on how network dynamics and structured connectivity jointly define the spatial and temporal profiles of neural correlations. Work w/ @roxana_zeraati, @SelfOrgAnna, @EngelTatiana: arxiv.org/abs/2207.07930 Here is a #tweeprint:

In decision-making tasks excitatory and inhibitory neurons show selectively for an upcoming choice. @EngelTatiana, @anne_churchland, and I explore the effects of inhibitory choice selectivity in decision making circuits using mean-field and RNN models. biorxiv.org/content/10.110…
