Bottom Line: During this period activity in right lateral orbitofrontal cortex (lOFC) was greater while participants rated visual stimuli as not beautiful than when they rated them as beautiful.We argue that this activity is associated with an initial negative aesthetic impression formation, driven by the relative hedonic value of stimuli regarded as not beautiful.Additionally, our results contribute to the understanding of the nature of the functional roles of the lOFC.

ABSTRACT
It is well established that aesthetic appreciation is related with activity in several different brain regions. The identification of the neural correlates of beauty or liking ratings has been the focus of most prior studies. Not much attention has been directed towards the fact that humans are surrounded by objects that lead them to experience aesthetic indifference or leave them with a negative aesthetic impression. Here we explore the neural substrate of such experiences. Given the neuroimaging techniques that have been used, little is known about the temporal features of such brain activity. By means of magnetoencephalography we registered the moment at which brain activity differed while participants viewed images they considered to be beautiful or not. Results show that the first differential activity appears between 300 and 400 ms after stimulus onset. During this period activity in right lateral orbitofrontal cortex (lOFC) was greater while participants rated visual stimuli as not beautiful than when they rated them as beautiful. We argue that this activity is associated with an initial negative aesthetic impression formation, driven by the relative hedonic value of stimuli regarded as not beautiful. Additionally, our results contribute to the understanding of the nature of the functional roles of the lOFC.

Activity significantly greater for stimuli rated as not beautiful rather than beautiful: 300–400 ms time-window.

pone-0038152-g005: Activity significantly greater for stimuli rated as not beautiful rather than beautiful: 300–400 ms time-window.

Mentions: Our results indicate that whereas images rated as beautiful were associated with activity in parietal regions from 300 ms onward [18], images rated as not beautiful were associated with activity in the right lateral orbitofrontal cortex between only 300 and 400 ms after stimulus onset (Figure 5 and Supporting Results S1) with a peak at 58/42/10 MNI coordinates. Hence, brain activity associated with images which participants rated as not beautiful was clearly distinct to that associated with images rated as beautiful. There were no brain activity differences between men and women at any time when rating not beautiful images.
