The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Conscious Processing and the Global Neuronal Workspace Hypothesis (2020, background): “The interactions between these brain structures enable distinct attractor states for the maintenance of different items in memory (Inagaki et al., 2019).”
Computation Through Neural Population Dynamics (2020, background): “Finally, Inagaki et al. (2019) found that delay period neural activity in mouse anterior lateral motor cortex moves toward stable fixed points that correspond to movement directions.”
Low-dimensional dynamics for working memory and time encoding (2020, result): “This is consistent with recent experiments on rodents (21, 22) that show that neural trajectories are low-dimensional, with a time-varying component that is dominated by ramping activity (46, 48).”
