Brain correlates of aesthetic expertise: a parametric fMRI study

Several studies have demonstrated that acquired expertise influences aesthetic judgments. In this paradigm we used functional magnetic resonance imaging (fMRI) to study aesthetic judgments of visually presented architectural stimuli and control-stimuli (faces) for a group of architects and a group of non-architects. This design allowed us to test whether level of expertise modulates neural activity in brain areas associated with either perceptual processing, memory, or reward processing. We show that experts and non-experts recruit bilateral medial orbitofrontal cortex (OFC) and subcallosal cingulate gyrus differentially during aesthetic judgment, even in the absence of behavioural aesthetic rating differences between experts and non-experts. By contrast, activity in nucleus accumbens (NAcc) exhibits a differential response profile compared to OFC and subcallosal cingulate gyrus, suggesting a dissociable role between these regions in the reward processing of expertise. Finally, categorical responses (irrespective of aesthetic ratings) resulted in expertise effects in memory-related areas such as hippocampus and precuneus. These results highlight the fact that expertise not only modulates cognitive processing, but also modulates the response in reward related brain areas.     

The Copenhagen Neuroaesthetics Conference: prospects and pitfalls for an emerging field

Neuroaesthetics is a young field of research concerned primarily with the neural basis of cognitive and affective processes engaged when an individual takes an aesthetic or artistic approach towards a work of art, a non-artistic object or a natural phenomenon. In September 2009, the Copenhagen Neuroaesthetics Conference brought together leading researchers in the field to present and discuss current advances. We summarize some of the principal themes of the conference, placing neuroaesthetics in a historical context and discussing its scope and relation to other disciplines. We also identify what we believe to be the key outstanding questions, the main pitfalls and challenges faced by the field, and some promising avenues for future research.     

Art as a metaphor of the mind

This paper focuses on the emergent neo-Jamesian perspective concerning the phenomenology of art and aesthetic experience. Starting from the distinction between nucleus and fringe in the stream of thought described by William James, it can be argued that our appreciation of a work of art is guided by a vague and blurred perception of a much more powerful content, of which we are not fully aware. Accordingly, a work of art is seen as a kind of metaphor of our mental life, objectified to be able to reach out to a much larger audience. However, it is a “realistic” theory rooted in evolutionary psychology, which claims that our mind developed within a framework shaped by environmental pressures. The aesthetics illustrated by several novelists develops a paradigm for this theory. The search for the neuronal correlates of stream of consciousness allows to make a comparison with the recent findings of neuroaesthetics and to reject its claim that it is unnecessary to take phenomenology and psychology into account.
