【 摘 要 】

Recently, Stănişor et al. (2013) showed in monkeys that the reward value of a visual stimulus is a good predictor of primary visual cortex (area V1) activity. Furthermore V1 neurons with the strongest reward value effect were also the ones showing the strongest attention effect. Taken together, the authors concluded on overlapping reward value and top-down attention, and suggested that theories about reward and top-down attention coding on vision might be unified. Alternatively, we suggest that the unified signal for attention and reward is actually an attentional control signal originating in the prefrontal cortex (PFC).
