Neuroaesthetics
is an application of brain imaging methods to the experience of works of art. Lately this endeavor has focused on the expression
and appreciation of visual and musical creations. The field has grown over the past decade in
tandem with advances in MRI, PET, CT scans and similar technology. Semir Zeki,
one of the field’s proponents, likens artists of all kinds to neuroscientists,
insofar as they also explore the capacity and potential of the human mind—whose
ultimate basis is the sum of countless neural and neurochemical processes occurring in brain tissue.
Dr. Zeki
states in the conclusion of his Statement
on Neuroaesthetics: “It is only by
understanding the neural laws that dictate human activity in all spheres—in law,
morality, religion and even economics and politics, no less than in art—that we
can ever hope to achieve a more proper understanding of the nature of man.” (http://neuroesthetics.org/statement-on-neuroesthetics.php)
The Wellcome
Laboratory of Neurobiology at University College London an institute devoted to
research in this area. Its goals include
investigating the connection between creative processes and brain functioning,
encouraging neurobiologists to include art and creativity as part of research
leading to greater understanding of the brain, and exploring the biological
basis of aesthetic experiences.
Underlying
this work are the assumptions that “visual art must obey the laws of the visual
brain”, that the purpose of visual art is the same as that of the visual brain—to
acquire knowledge—and that visual artists are essentially doing the same thing
that neuroscientists do, just with different tools and methods. (http://neuroesthetics.org/institute.php)
Presumably,
these assumptions will apply to other areas of the brain dedicated to different
forms of creative expression, for example writing and its complementary
process, reading.
As an
aside, your humble blogger is by training a speech-language pathologist. At a professional conference earlier this
month in Chicago, I attended a presentation entitled “The Believing Brain:
Prefrontal Cortex and Brain Injury Recovery” authored by Jordan Grafman of the Rehabilitation
Institute of Chicago. New brain imaging
techniques have also been applied in the investigation of parts of the brain
involved in ‘human social beliefs’—specifically, attitudes about religion,
morals, and the law.
To
date, no single location or circuit in the brain that appears to be dedicated to
these higher level functions—there is no ‘God spot’. However, in one study, fMRI scans showed
increased activity in the pre-frontal cortex on both sides of the brain, in the
associative areas of the temporal lobes, and in portions of the occipital and
parietal regions during religious thinking tasks. Interestingly, some research suggests that
damage to areas of the pre-frontal cortex and deeper limbic system tissue may
alter political beliefs and judgments about morality and the legal consequences
of behavior.
In
today’s New York Times is a fascinating
article about a neuroaesthetic experiment involving a Dutch author and journalist
named Arnon Grunberg, (“Wired: Putting a Writer and Readers to a Test”, NYT, 11/30/13). The author’s brain is being scanned as he
writes his next novella. Brain activity
readings are coordinated with the location of Mr. Grunberg’s cursor as he
writes sections that have various dominant emotional tones. Eventually, 50 subjects will be asked to read
Grunberg’s novel as their brains are scanned—the data will then be analyzed with
respect to patterns that might show a connection between the author’s creative
process and its perception and appreciation in the brains of his readers.
An
obvious practical application: imagine
if publishers could hook up a focus group of readers to brain imaging devices
and evaluate in advance whether a book could become a bestseller. In the case of horror fiction, would a given manuscript excite the areas of the brain responsible for sensations of fear, horror or passion? Or would it merely stimulate the centers responsible for sleep?
Marketing the book, even creating the book, could be tailored to the neurobiological responses of a reader test group. Maybe even literary criticism itself can be found to have a predictable, quantifiable neurological basis.
