The Role of Left Dorsolateral Prefrontal Cortices in Aesthetic Valuation

Abstract

As discussed in both the original study and the current chapter, the dorsolateral prefrontal cortex (DLPFC) is a required neural player in the aesthetic appraisal and a basic stage of the aesthetic experience. As the distinct activation that the authors found in the neuroimaging study occurred when participants rated as beautiful natural, artistic, and decorative stimuli, we concluded that left DLPFC responded to aesthetic qualities in general and not to specific artistic qualities. More recent studies indicate that the function of the LPFC in relation to aesthetics may be to exercise cognitive control to direct attention with a proper aesthetic orientation. Other studies suggest that LPFC is part of a frontal “evaluative” network which supports an analysis of emotional response and personal relevance. Specifically, left DLPFC seems to affect the evaluation of different images, disengaging from a habitual mode of identifying objects in order to adopt an aesthetic perspective.
