Many of our every-day decisions involve prolonged deliberation, followed by a categorical commitment to one of the alternative options. Research over the past decade has shown that the brain regions involved in deliberative decision-making are widely distributed across the cerebral cortex. How do these regions coordinate their activities during decision-making and make us commit to a choice? I will present a series of MEG and fMRI studies approaching this problem by measuring neural activity in human subjects who judged their perceptual experience of degraded, or perceptually bistable, visual stimuli. Such stimuli provoke variable behavioral choices in the face of constant sensory input. We exploited this variability to isolate the decision processes that, inside the brain, link sensory representations to behavioral choice. Our results suggest that the state of deliberation is associated with long-range reverberation of neural activity across several cortical processing stages. Subsequently, the final decision seems to induce a massive state change that reaches down to the earliest sensory stages. Specifically, in primary visual cortex, this state change reflects the selected decision, suggesting that even primary visual cortex is strongly driven by internal feedback signals triggered by our decisions. I will speculate that this post-decisional state change underlies our subjective commitment to a choice, and I will discuss possible underlying neural mechanisms.
