ARTISTIC THINKING AND CEREBRAL ASYMMETRY
Journal Title: Acta Neuropsychologica - Year 2003, Vol 1, Issue 2
Abstract
The study of drawings by patients with focal lesions in the right or left hemisphere can help us understand how artistic thinking is supported by brain structures. The role of the right hemisphere is significant at the early stage of the creative process. The right hemisphere is a generator of nonverbal visuo-spatial thinking. It operates with blurred nonverbal images and arranges them in a visual space. With the help of iconic signs the right hemisphere reflects the world and creates perceptive visual standards which are stored in long-term right hemisphere memory. The image which appears in the inner space needs to be transferred into an essentially different language, i.e. a left hemispheric language of signs. This language operates with a finite number of discrete units, logical succession, and learned grammar rules. This process can be explained by activation (information) transfer from the right hemisphere to the left. Thus the natural and spontaneous creative process, which is finished by a conscious effort, can be understood as an activation impulse transfer from the right hemisphere to the left and back.
