| left Prefrontal dorsolateral cortex (l-PDC)
PDC is a brain region that participates, as a center of perception–action interface, in multiple brain functions. Incoming information from posterior parietal and occipital areas is processed in the PDC in a more complex fashion that is required to plan a corresponding action. In this way a particular set of perceptual stimuli engenders a particular set of actions (43). Actually, PDC is critical ‘‘for the monitoring of multiple events in working memory’’ (44) and plays a key role ‘‘in making decisions that call for the consideration of multiple sources of information’’ (45). Consequently, PDC has a significant role in functions related to decision making (46, 47) and visuospatial working memory (48). The activation of PDC in an aesthetic task should not surprise us because when deciding about the ‘‘beautiful’’ condition of stimuli, a judgment requiring visuospatial memory is needed. PDC and cingulated cortex are known to activate during judgment tasks (49). Although the cingulated cortex is activated in both conditions (‘‘beautiful’’ and ‘‘not beautiful’’),

Our experimental results clearly show that cortical activity in the PDC relates with aesthetic perception. Prefrontal activity associated with aesthetic judgment is observed in both aesthetic and nonaesthetic conditions during 400- to 900-ms latency (‘‘aesthetic’’ and ‘‘nonaesthetic’’ referring to participants’ judgment). However, this activity is greater in the left hemisphere under the aesthetic condition.

| aesthetic(beauty) perception to ugly, neutral visual stimuli
| Orbitofrontal cortex (aesthetic), Mortor cortex (nonaesthetic)
The judgment of a painting as beautiful or not correlates with specific brain structures, principally the orbitofrontal cortex, known to be engaged during the perception of rewarding stimuli (Aharon et al. 2001; Francis et al. 1999; Rolls 2000; Small et al. 2001) and, perhaps surprisingly, the motor cortex. Less predictably, the results also tell us that there is no separate structure that is specifically engaged when stimuli are perceived as ugly. Parameter estimates show that it is rather a change in relative activity in the orbito-frontal cortex that correlates with the judgment of beauty and of ugliness.
