neuroscience to determine and understand the neurological mechanisms involved. Neuroaesthetics approaches can be either descriptive or experimental. Descriptive neuroaesthetics refers to the practice of mapping properties of the brain onto aesthetic experiences. For example, if color is important to the experience of Fauvist art, then it is likely that areas of the brain that process color will be engaged when looking at such art. The claims of descriptive neuroaesthetics are regarded as hypothesis-generating and are typically qualitative in nature. Experimental neuroaesthetics, like any experimental science, produces data that are quantitative and vetted statistically. Experimental neuroaesthetics tests hypotheses, predicts results, and invites replication or falsification. The typical experimental methods used are those of cognitive neuroscience: fMRI, ERP, TMS, TDCS, and neuropsychology. Critics of neuroaesthetics typically target descriptive and not experimental neuroaesthetics. The link between specific brain areas and artistic activity is of great importance to the field of neuroesthetics. This can be applied both to the ability to create and interpret art. A common approach to uncover the neural mechanisms is through the study of individuals, specifically artists, with neural disorders such as savant syndrome or some form of traumatic injury. The analysis of art created by these patients provides valuable insights to the brain areas responsible for capturing the essence of art. The aesthetic enjoyment of individuals can be investigated using brain imaging experiments. When subjects are confronted with images of a particular level of aesthetics, the specific brain areas that are activated can be identified. It is argued that the sense of beauty and aesthetic judgment presupposes a change in the activation of the brain's reward system. In 2004, Helmut Leder has developed a broad research program on the psychology of aesthetics and the arts. This program was introduced as a cognitive model of the appreciation of art in a paper published in the British Journal of Psychology. This model has served to frame many studies on the cognitive foundations of art, neuroaesthetics, product design, and web design, among other fields. A crucial aspect of research lies in whether aesthetic judgment can be thought of as a bottom-up process driven by neural primitives or as a top-down process with high level cognition. Neurologists have had success researching primitives. However, there is a need to define higher level abstract philosophical concepts objectively with neural correlates. It is suggested that aesthetic experience is a function of the interaction between top-down, intentional
