It is questionable whether the theories can capture the evocativeness or originality of individual works of art. Experiments performed may not account for these theories directly. Also, current experimentation measures a person's verbal response to how they feel about art which is often selectively filtered. Ramachandran suggests the use of galvanic skin response to quantify the judgment associated viewing aesthetics. Overall, it can be argued that there is lack of proportion between the narrow approach to art taken by researchers versus the grand claims they make for their theories. Future directions and related fields Since 2005 the notion of bridging brain science and the visual arts has blossomed into a field of increasing international interest. In his 2008 book, Neuroarthistory: from Aristotle and Pliny to Baxandall and Zeki, Professor John Onians of the University of East Anglia considers himself to be at the forefront of the field of neural scientific biased art historical research, although such a 'history' is much shorter than Onians would have us believe. Many historical figures he deals with as precursors for neuroarthistory (Karl Marx, for example) have very little to do with modern neuroscience as it is understood today. Contemporary artists like Mark Stephen Smith (William Campbell Gallery, USA), Guillaume Bottazzi and others have developed extensive bodies of work mapping the convergence of brain science and painting. Smith's work explores fundamental visual analogies between neural function and self-expression in abstract art. The past decade has also seen a corresponding growth in the aesthetics of music studied from neuroscientific approaches. Psychological and social approaches to art help provide other theories of experience.
