Beauty is in the eyes of the beholder. Men and women generally are drawn to dissimilar styles of paintings. A man’s preference is on the left (illustration from Wikipedia) and a woman’s is on the right (illustration from Happy Painting).
In behavioral studies, men and women are known to rate the beauty of artistic and decorative stimuli in different ways. Although this tendency is recognized, the reason why is not. Recently, Camilo J. Cela-Conde and his colleagues began to explore the answer to this question. This is what they found.
During visual artistic appreciation, a particular area of the brain, the parietal lobe, was stimulated in both sexes. However, the sides of the brain that displayed activity in the 2 sexes were not the same. In females, it was on both sides and in men, it was primarily the right. The authors explained, “Our results showing an early activity of parietal areas for stimuli rated as beautiful in both sexes seem to indicate that the processing of spatial relations is crucial in the human appreciation of beauty. However … activity in the parietal regions is bilateral in the case of women but lateralized to the right hemisphere in the case of men.”

To reach their conclusion, the researchers studied 10 female and ten male neurobiology students. Their average age was 23.6 years. They had no earlier training or special interest in art. All were shown the same set of photographs of artistic paintings or natural objects that were divided into 5 clusters. There were 50 pictures each for the first 4: abstract, classic, impressionist, and postimpressionist art. The final group consisted of 200 photographs of landscapes, artifacts, urban scenes, and similar.
Magnetoencephalography (MEG) was used to record brain activity and appropriate data analysis was applied. MEG is a method for detecting changes in magnetic fields produced by postsynaptic neuron activity with a time resolution of milliseconds. For more detail, please see the paper.
