There are cells in the brain that respond to faces. This is one of the reasons that I deal with portraiture. We can learn a lot about our perception of facial expression from the behavior of these cells.

The task of neural science is to explain behaviour in terms of the activities of the brain. How does the brain marshall its millions of individual nerve cells to produce behaviour, and how are these cells influenced by the environment...? The last frontier of the biological sciences – their ultimate challenge – is to understand the biological basis of consciousness and the mental processes by which we perceive, act, learn, and remember.

The problem for many people is that we cannot point to the underlying biological bases of most psychiatric disorders. In fact, we are nowhere near understanding them as well as we understand disorders of the liver or the heart.

Not only Freud but artists and writers were also interested in the unconscious. It was medicine that made the first steps toward modernity.

In art, as in science, reductionism does not trivialize our perception - of color, light, and perspective - but allows us to see each of these components in a new way.

I see psychoanalysis, art and biology ultimately coming together, just like cognitive psychology and neuroscience have merged.
