Accordingly, value modulates the activity of sensorimotor neurons involved in initiating movements toward one of two competing decision alternatives. However, little is known about how value influences the acquisition and ^^^^^^^^^^^^^^^不知道有没有新的进展或是更多的解释? representation of incoming sensory information or about the neural mechanisms that track the relative value of each available stimulus to guide behavior. Here, fMRI revealed value-related modulations throughout spatially selective areas of the human visual system in the absence of overt saccadic responses (including in V1). These modulations were primarily associated with the reward history of each stimulus and not to self-reported estimates of stimulus value. Finally, subregions of frontal and parietal cortex represent the differential value of competing alternatives and may provide signals to bias spatially selective visual areas in favor of more valuable stimuli. --以下是原文出处-- http://linkinghub.elsevier.com/retrieve/pii/S0896627308009513 -- 欢迎光临我的网志 http://abs1130.spaces.live.com/ 我的电台 http://122.116.0.127:8000/ --
