Week 4: Neuroscience + Art

            While we generally think of the brain’s sole function as controlling our body and maintaining our consciousness, it can also be manipulated to create art through imaging the brain, tricking the brain with illusions, and manipulating the chemicals inside the brain. In addition to the use of Brainbow to randomly distinguish and map individual neurons, Carbocyanine dye labeling can be used to label axon tracts in the brain, creating beautiful, scientifically useful images.

            Some artists exploit their knowledge of neuroscience to create optical illusions such as Suzanne Anker’s fMRI Butterfly, which trick the brain into perceiving images differently than they actually are. One interesting application of these illusions is in the diagnosis of Schizophrenia. Schizophrenics, as well as some brain injury sufferers, have facial recognition defects that prevent them from falling for the Hollow Face optical illusion. A healthy brain sees the concave inside of a face mask, but interprets it to be convex because the brain’s idea of what it expects overpowers the actual visual information.

            A significantly more controversial method of creating art is through altering the brain with hallucinogenic substances such as LSD and psilocybin. The compounds act on the brain’s neurotransmitters, creating art in the subject’s mind when they close their eyes, as well as influencing artistic expression. The use of drugs to create an altered mental state has famously lead to many notable contributions including Freud’s invention of psychoanalysis and Crick’s discovery of the double helix structure of DNA.
Other artists famously influenced by the effects of LSD include Aldous Huxley, Jim Morrison and Steve Jobs. Some scholars even believe that these hallucinations were the basis for certain events in religious scripture.

            One piece I really enjoyed was Bryan Lewis Saunders’ series of self-portraits, each while on different drug. It was interesting to see how different mental states would produce completely different images.

            While much controversy surrounds the use of life as an expressive medium, I believe that no harm comes to society as long as artists are aware of the consequences these procedures have on their own bodies, perform them safely and don't harm other organisms unnecessarily. Regarding the use of controlled substances, a significantly more complex issue is presented. Those under the influence may have lapses in judgment (driving while intoxicated) that put others in danger or experience brain damage as a result of improper use, creating a burden on the health care system. Consequentially, a pragmatic ethical approach must be applied to such situations.
