"My child could have done that!" Wrong – neuroaesthetics is starting to show us why abstract art can be so beguiling

STANDING in front of Jackson Pollock's Summertime: Number 9A one day, I was struck by an unfamiliar feeling. What I once considered an ugly collection of random paint splatters now spoke to me as a joyous celebration of movement and energy, the bright yellow and blue bringing to mind a carefree laugh.

It was my road-to-Damascus moment - the first time a piece of abstract art had stirred my emotions. Like many people, I used to dismiss these works as a waste of time and energy. How could anyone find meaning in what looked like a collection of colourful splodges thrown haphazardly on a 5.5-metre-wide canvas? Yet here I was, in London's Tate Modern gallery, moved by a Pollock.

Since then, I have come to appreciate the work of many more modern artists, who express varying levels of abstraction in their work, in particular the great Piet Mondrian, Paul Klee, and contemporary artist Hiroshi Sugimoto. Even so, when I tried to explain my taste, I found myself lost for words. Why are we attracted to paintings and sculptures that seem to bear no relation to the physical world?

Little did I know that researchers have already started to address this question. By studying the brain's responses to different paintings, they have been examining the way the mind perceives art. Although their work cannot yet explain the nuances of our tastes, it has highlighted some of the unique ways in which these masterpieces hijack the brain's visual system. 

The studies are part of an emerging discipline called neuroaesthetics, founded just over 10 years ago by Semir Zeki of University College London. The idea was to bring scientific objectivity to the study of art, in an attempt to find neurological bases for the techniques that artists have perfected over the years. It has already offered insights into many masterpieces. The blurred imagery of Impressionist paintings seems to tickle the brain's amygdala, for instance, which is geared towards detecting threats in the fuzzy rings of our peripheral vision. Since the amygdala plays a crucial role in our feelings and emotions, that finding might explain why many people find these pieces so moving.
