The neural link between subjective value and decision entropy

摘要: We evaluated whether the brain organises value and confidence signals in a systematic fashion that reflects overall desirability of decision options. If so, regions respond positively to increases should also confidence. Likewise, negatively both be widespread. strongly confirmed these predictions through model-based fMRI analysis mixed gambles task assessed subjective (SV) inverse entropy (iDE), which is related Purported areas more signalled iDE than SV, underscoring how intertwined are. Smooth maps tied actions transitioned from positive SV ventromedial prefrontal cortex negative dorsal medial cortex. This non-accidental organisation was found across strongest purported areas.
