Abstract: 
Understanding the way in which value is represented in the human brain is a critical question in the study of the humanreward learning system and decision-making in general. Economic decisions between different goods are typicallymade on the basis of associated valuations of the available goods. Previous work using functional magnetic resonanceimaging has implicated areas of the orbital frontal cortex in the encoding of this decision value signal. However it is notknown whether this signal contains information specific to the good in question or rather, homogeneously reflects valueacross all goods. We aim to answer this question by attempting to decode BOLD signals using multivariate patternclassification techniques while participants placed economic valuations on items drawn from three distinct categories.
