Mouse posterior parietal cortex dynamics during a virtual-navigation evidence-a…

Mouse posterior parietal cortex dynamics during a virtual-navigation evidence-accumulation task transition rapidly between distinct activity patterns, and each evidence cue or behavioural choice produces seconds-long modifications to transition probabilities — implementing accumulation through dynamical short-term memory rather than explicit winner-take-all competition.
