"Vangelis composed special music to accompany video recordings included in the medical book "Microsurgery With Video Tapes", published in 1998. The video tapes capture 35 microneurosurgical cases that, together with the book, intend to provide training for people active in this field.
The author of the book, Dr. Stergios Tegos is a good friend of Vangelis. He explains in the introduction of the book that he had the pleasure over the years to learn the neurophysiological processes of Vangelis' musical creativity and the methods by which he creates music. Dr Tegos reveales he had asked Vangelis for two favours. The first was to allow him to obtain a magnetic resonance image of Vangelis' brain. The second was for Vangelis to compose music to accompany the video recordings for his book. Vangelis fulfilled the second request."
