Decoding and perturbing decision states in real time

Nature, Published online: 20 January 2021; doi:10.1038/s41586-020-03181-9

In macaque motor cortex, moment-to-moment fluctuations in neurally derived decision variables are tightly linked to decision state and predict behavioural choices with better accuracy than condition-averaged decision variables or the visual stimulus alone, and can be used to distinguish between different models of decision making.
