We present a theory of human artistic experience and the neural mechanisms that mediate it. Any theory of art has to ideally have three components. The logic of art: whether there are universal rules or principles; The evolutionary rationale: why did these rules evolve and why do they have the form that they do; What is the brain circuitry involved? Our paper begins with a quest for artistic universals and proposes a list of ‘Eight laws of artistic experience’ -- a (...) set of heuristics that artists either consciously or unconsciously deploy to optimally titillate the visual areas of the brain. One of these principles is a psychological phenomenon called the peak shift effect: If a rat is rewarded for discriminating a rectangle from a square, it will respond even more vigorously to a rectangle that is longer and skinnier that the prototype. We suggest that this principle explains not only caricatures, but many other aspects of art. Example: An evocative sketch of a female nude may be one which selectively accentuates those feminine form-attributes that allow one to discriminate it from a male figure; a Boucher, a Van Gogh, or a Monet may be a caricature in ‘colour space’ rather than form space. Even abstract art may employ ‘supernormal’ stimuli to excite form areas in the brain more strongly than natural stimuli. Second, we suggest that grouping is a very basic principle. The different extrastriate visual areas may have evolved specifically to extract correlations in different domains , and discovering and linking multiple features into unitary clusters -- objects -- is facilitated and reinforced by direct connections from these areas to limbic structures. In general, when object-like entities are partially discerned at any stage in the visual hierarchy, messages are sent back to earlier stages to alert them to certain locations or features in order to look for additional evidence for the object . Finally, given constraints on allocation of attentional resources, art is most appealing if it produces heightened activity in a single dimension rather than redundant activation of multiple modules. This idea may help explain the effectiveness of outline drawings and sketches, the savant syndrome in autists, and the sudden emergence of artistic talent in fronto-temporal dementia. In addition to these three basic principles we propose five others, constituting a total of ‘eight laws of aesthetic experience’. (shrink)

Almost everyone who has a limb amputated will experience a phantom limb--the vivid impression that the limb is not only still present, but in some cases, painful. There is now a wealth of empirical evidence demonstrating changes in cortical topography in primates following deafferentation or amputation, and this review will attempt to relate these in a systematic way to the clinical phenomenology of phantom limbs. With the advent of non-invasive imaging techniques such as MEG (magnetoencephalogram) and functional MRI, topographical reorganization (...) can also be demonstrated in humans, so that it is now possible to track perceptual changes and changes in cortical topography in individual patients. We suggest, therefore, that these patients provide a valuable opportunity not only for exploring neural plasticity in the adult human brain but also for understanding the relationship between the activity of sensory neurons and conscious experience. We conclude with a theory of phantom limbs, some striking demonstrations of phantoms induced in normal subjects, and some remarks about the relevance of these phenomena to the question of how the brain constructs a 'body image.'.

Neurological syndromes in which consciousness seems to malfunction, such as temporal lobe epilepsy, visual scotomas, Charles Bonnet syndrome, and synesthesia offer valuable clues about the normal functions of consciousness and ‘qualia’. An investigation into these syndromes reveals, we argue, that qualia are different from other brain states in that they possess three functional characteristics, which we state in the form of ‘three laws of qualia’. First, they are irrevocable: I cannot simply decide to start seeing the sunset as green, or (...) feel pain as if it were an itch; second, qualia do not always produce the same behaviour: given a set of qualia, we can choose from a potentially infinite set of possible behaviours to execute; and third, qualia endure in short-term memory, as opposed to non-conscious brain states involved in the on-line guidance of behaviour in real time. We suggest that qualia have evolved these and other attributes because of their role in facilitating non-automatic, decision-based action. We also suggest that the apparent epistemic barrier to knowing what qualia another person is experiencing can be overcome by using a ‘bridge’ of neurons; and we offer a hypothesis about the relation between qualia and one's sense of self.

Several recent lines of inquiry have pointed to the amygdala as a potential lesion site in autism. Because one function of the amygdala may be to produce autonomic arousal at the sight of a significant face, we compared the responses of autistic children to their mothers’ face and to a plain paper cup. Unlike normals, the autistic children as a whole did not show a larger response to the person than to the cup. We also monitored sympathetic activity in autistic (...) children as they engaged in a wide range of everyday behaviours. The children tended to use self-stimulation activities in order to calm hyper-responsive activity of the sympathetic (`fight or flight’) branch of the autonomic nervous system. A small percentage of our autistic subjects had hyporesponsive sympathetic activity, with essentially no electrodermal responses except to self-injurious behaviour. We sketch a hypothesis about autism according to which autistic children use overt behaviour in order to control a malfunctioning autonomic nervous system and suggest that they have learned to avoid using certain processing areas in the temporal lobes.

Neurological syndromes in which consciousness seems to malfunction, such as temporal lobe epilepsy, visual scotomas, Charles Bonnet syndrome, and synesthesia offer valuable clues about the normal functions of consciousness and ‘qualia’. An investigation into these syndromes reveals, we argue, that qualia are different from other brain states in that they possess three functional characteristics, which we state in the form of ‘three laws of qualia ’ based on a loose analogy with Newton’s three laws of classical mechanics. First, they are (...) irrevocable: I cannot simply decide to start seeing the sunset as green, or feel pain as if it were an itch; second, qualia do not always produce the same behaviour: given a set of qualia, we can choose from a potentially infinite set of possible behaviours to execute; and third, qualia endure in short-term memory, as opposed to non-conscious brain states involved in the on-line guidance of behaviour in real time. We suggest that qualia have evolved these and other attributes (e.g. they are ‘filled in’) because of their role in facilitating non-automatic, decision-based action. We also suggest that the apparent epistemic barrier to knowing what qualia another person is experiencing can be overcome simply by using a ‘bridge ’ of neurons; and we offer a hypothesis about the relation between qualia and one’s sense of self.

V.S. Ramachandran and William Hirstein's thought-provoking article ‘The science of art: a neurological theory of aesthetic experience’ and the accompanying commentaries raise serious questions about what a science of art is. Unfortunately this short piece will only be able to address them broadly. Overall the problems arise from the exclusion of neurological studies of artists, the exclusion of the artist's experience, and the premises of the theory, which are based on problematic valuations related to aesthetics and spirituality. (...) With these valuations, for which there is no scientific proof, the model is unable to sufficiently address the scope of what artists do and what art forms are. While it is my view that the Ramachandran and Hirstein theory is fundamentally flawed, it is likely the flaws are due to implicit assumptions rather than explicit intentions. (shrink)

If it is true, as one of its founders, George Miller, tells us, that cognitive science was born in 1956, then by human aging standards it is coming upon a mid-life crisis. Crises, as Kuhn has taught us, often precipitate radical change, in science as well as in individuals. It should therefore not be surprising to find that cognitive scientists have begun to look to the future and predict, or hope, that it will include both the beautiful and the good. (...) Thus it is that the neuroscientist, Semir Zeki, has recently declared: “We are at the threshold of a great enterprise” which he calls neuroesthetics. His optimism about that enterprise has been echoed by a number of other researchers; and for the most part, their hopefulness is based on discoveries about how pictures are perceived. So, for example, V. S. Ramachandran and William Hirstein have said that by understanding the neuropsychological principles of picture perception, we may come to understand the very “essence of art”. Indeed, by identifying perceptual principles in the right way, according to David Gilden, we may discover common ground for normative disciplines of all stripes; a theory of “what is sexy, what is virtue, or what is a good buy”.

[opening paragraph]: Dr. Ramachandran is a distinguished researcher in the field of cognitive neuroscience whose work is grounded in impressive clinical data. As a scientific materialist, he has provided powerful arguments against the metaphysical notion of the ‘self', suggesting that our consciousness is really a biological function of the brain. He and his collaborator, William Hirstein, have now turned to human artistic activity, putting forward the argument that it is essentially a product of neural mechanism. They employ (...) the experimental ‘peak shift effect’ to sustain this hypothesis. The experiment demonstrates that a rat's cognitive achievements are related to the reward it receives for discriminating different shapes. Applying this principle to human responses to the visual image, they argue that certain simplified and exaggerated images, as for instance, caricature, appeal to our emotions and have the innate ability to give us pleasure. Furthermore, the binding of correlated features creates unitary objects that provide further grounds for aesthetic appeal. This is because, given our limited ability to concentrate, the most appealing art is one that produces heightened activity within a single dimension. (shrink)

This essay exposes several problems with reductionist approaches to art, placing some specific focus on ‘The Science of Art’ by Vilayanur S. Ramachandran and William Hirstein . Their article seems to be representative of this genre in general, though particularly egregious in certain dimensions. My approach will differ greatly from that of a neuroscientist, philosopher, or psychologist, since I primarily take a critical feminist, social-literary perspective. I will argue that reductionist approaches to art are an intoxicating composite (...) of arrogance, insight, confusion and precision, an amalgam that challenges the commentator to distinguish what is worth praising, what is worth attacking, and what is best left alone. In particular, I will demonstrate that Ramachandran and Hirstein confuse arousal with beauty, with the disastrous result of excluding most of what is usually taken to distinguish ‘high’ art from its ‘lower’ forms, such as advertising, industrial design, and pornography.

This paper comments on an article by V.S. Ramachandran and William Hirstein (JCS,1999) in which they purport to be identifying the neurological principles of beauty. I draw attention to the way the problem of beauty is construed in the philosophical literature by Mary Mothersill (1984) and Immanuel Kant (Critique of Judgment). I argue that Ramachandran and Hirsteins' principles do not address the problem of beauty because they do not differentiate between the experience of beauty and other (...) closely related phenomena. I then show how one might address the problem of beauty within the framework that they have adopted. (shrink)
