Nancy Andreasen: Secrets of the Creative Brain

Nancy Andreasen is a leading neuroscientist and psychiatrist at the University of Iowa whose fascinating research into the creative mind has been informed in part by the stream of remarkable writers who gather there. She is now conducting a study that uses neuroimaging to visualize the creative brain in action, examining both artists and scientists. Her work also examines the roles of nature v. nurture and the relationship between creativity and mental illness.

The Relationship Between Creativity and Mental Illness

The science behind the “tortured genius” myth and what it reveals about how the creative mind actually works.

All the writers were euthymic at the time that I interviewed them, and so they could look back on their periods of depression or mania with considerable detachment. They were also able to describe how abnormalities in mood state affected their creativity. Consistently, they indicated that they were unable to be creative when either depressed or manic.

.. Creativity in other fields may, however, be compatible with an illness like schizophrenia, particularly those fields in which the creative moment is achieved by flashes of insight about complex relationships or by exploring hunches and intuitions that ordinary folk might find strange or even bizarre.

.. Many personality characteristics of creative people … make them more vulnerable, including openness to new experiences, a tolerance for ambiguity, and an approach to life and the world that is relatively free of preconceptions. This flexibility permits them to perceive things in a fresh and novel way, which is an important basis for creativity. But it also means that their inner world is complex, ambiguous, and filled with shades of gray rather than black and white. It is a world filled with many questions and few easy answers. While less creative people can quickly respond to situations based on what they have been told by people in authority — parents, teachers, pastors, rabbis, or priests — the creative person lives in a more fluid and nebulous world. He or she may have to confront criticism or rejection for being too questioning, or too unconventional. Such traits can lead to feelings of depression or social alienation. A highly original person may seem odd or strange to others. Too much openness means living on the edge. Sometimes the person may drop over the edge… into depression, mania, or perhaps schizophrenia.

.. Creative ideas probably occur as part of a potentially dangerous mental process, when associations in the brain are flying freely during unconscious mental states — how thoughts must become momentarily disorganized prior to organizing. Such a process is very similar to that which occurs during psychotic states of mania, depression, or schizophrenia. In fact, the great Swiss psychiatrist Eugen Bleuler, who gave schizophrenia its name, described a “loosening of associations” as its most characteristic feature

.. All human beings (and their brains) have to cope with the fact that their five senses gather more information than even the magnificent human brain is able to process. To put this another way: we need to be able to ignore a lot of what is happening around us — the smell of pizza baking, the sound of the cat meowing, or the sight of birds flying outside the window — if we are going to focus our attention and concentrate on what we are doing (in your case, for example, reading this book). Our ability to filter out unnecessary stimuli and focus our attention is mediated by brain mechanisms in regions known as the thalamus and the reticular activating system.

.. Some of the writers in her study, upon realizing they had a tendency to be too sociable, employed various strategies for keeping themselves isolated from human contact for sizable stretches of time in order to create. (Victor Hugo famously locked away all his clothes to avoid the temptation of going out while completing The Hunchback of Notre Dame in 1830, which he wrote at his desk wearing nothing but a large gray shawl.)
