Mouse frontal cortex maintains short-term memory through a modular organization…

Mouse frontal cortex maintains short-term memory through a modular organization across hemispheres: each hemisphere retains persistent activity during perturbations of the other, a dynamic gating mechanism prevents corrupt information from spreading, and similar redundant modular representations emerge in network models trained for robust persistent dynamics.
