Cortex-wide Dynamics of Internal Decisions About Behavioral Context.

ABSTRACT: Many human decisions manifest in the outside world as motor actions. Correspondingly, neural signals reflecting decision formation are expressed in neural populations encoding the final action. Some decisions, however, are internal, shaping overt behavior indirectly through the selection of policies or rules that guide elementary sensory-motor decisions. We studied the human brain dynamics underlying internal decisions about the stimulus-response mapping rule for reporting visual orientation judgments. The rule changed unpredictably in a hidden fashion, and participants tracked it by accumulating ambiguous sensory cues. Computational model-based decoding of source-level magnetoencephalography data uncovered representations of the internal belief about the active rule in many areas, includi
