Efficient attention to our environment facilitates the decisions that need be executed in daily life. Filtering critical from noncritical information may require neural organization of multiple brain regions. Combining lesion techniques and rodent version Wisconsin card sorting task humans, we show at least two types attentional processing systems reside cingulate prefrontal cortices depending on demands requiring shifts within or between sets meaningful cues, respectively. This for shifting either perceptual dimensions is dependent, this type provides evidence transcend separate modality while subdividing executive control attention. The results suggest anterior posterior are when closely related cues (i.e., a dimension set) by suppressing interference irrelevant background information, whereas cortex disparate sets) (Dias et al., 1996a,b; Birrell Brown, 2000). Based theories Mackintosh (1965, 1975; Sutherland Mackintosh, 1971), it suggested important decreasing information. In general, deficit disorders affect both children adults, current medications associated parietal cortical more less than system.
