The dorsal anterior cingulate cortex (dACC) is thought to play a critical role in forming associations between rewards and actions. Currently available physiological data, however, remain inconclusive regarding the question of whether dACC neurons carry information linking particular actions reward or, instead, encode abstract independent specific Here we show that firing rates majority population studied an eight-option variably rewarded choice task were sensitive both saccade direction value. Furthermore, influences on neuronal activity approximately equal magnitude over range tested statistically independent.
