Abstract: Humans can make abstract choices independent of motor actions. It is unclear under which conditions, where and when in the brain abstract choices are represented, and whether these representations generalize to contexts in which choices are linked to actions. To disentangle sensory, decision, and motor stages, we measured MEG signals in 33 participants during variants of a sensorimotor decision-making task with known and unknown choice-response mapping. Using multivariate decoding, we found reliable stimulus, choice and response information with distinct cortical source distributions. Choice representations were invariant to whether the response mapping was known at the time of stimulus presentation. Our results suggest the presence of widespread abstract choice representations, independent of sensory and motor representations.
