Professor Semir Zeki
From Wikipedia, the free encyclopedia
Semir Zeki is Professor of Neurobiology
at University College London. His main interest is the organization
of the primate visual brain. He published his first scientific
paper in 1967. Since then he has written over 150 papers and
three books: A Vision of the Brain (1993), Inner Vision: an
exploration of art and the brain (1999) [which has been translated
into six languages] and La Quête de l’essentiel, which
he co-authored with the late French painter Balthus (Count
Klossowski de Rola). In 1994, he began to study the neural
basis of creativity and the aesthetic appreciation of art.
In 2001, he founded the Institute of Neuroesthetics[1], based
mainly in Berkeley, California.
Formative influences
When at school, Zeki got acquainted with
work on the brain, especially from JZ Young and vowed to work
with him, which he did, at University College London. He initially
studied anthropology, then switched to medicine, finally taking
a PhD in anatomy.
Zeki then worked as a post-doctoral fellow
at the University of Wisconsin-Madison, and at St. Elizabeths
Hospital, Washington, DC before returning to University College
London as Henry Head Research Fellow of the Royal Society.
Time at University College London
Since 1970 Zeki has been based at University
College, being appointed the Professor of Neurobiology in
1980.
He was Co-Head of the Wellcome Department
of Cognitive Neuroscience at University College London from
1994 to 2001.
Zeki has conducted anatomical and physiological
studies of the primate visual brain.
Since 1987, he has used positron emission
tomography (PET) and functional magnetic resonance imaging
(fMRI) to study the human visual brain. Zeki has lectured
on the subject the world over. Among the more than 50 named
lectures he has given are The Ferrier Lecture (Royal Society),
the Sir Humphry Davy Lecture (Académie des Sciences, Paris),
the Philip Bard Lecture (Johns Hopkins University), the Paul
Broca Lecture (Lyon), the Getty Public Lecture (Los Angeles),
the David Marr Lecture (Cambridge), the Koetser Lecture (Zurich),
the Burda Lecture (Munich), Sigma Tau Lecture (Milan), the
Donders Lecture (Netherlands), and the Hayaishi Lecture (Osaka)
and Carl Bernhard Lecture (Stockholm). He has also lectured
specifically on art and the brain at various institutions
around the world, including the Tate Gallery (London), the
Musée d’Orsay (Paris), Gemäldegalerie (Berlin), the Getty
Museum (Los Angeles), Akademie der Bildenden Kunst (Vienna)
and the Mondriaanhuis, Amersfoort, the Netherlands. In 2003
he curated the exhibition Colore e Cervello at the Casa Rusca
in Locarno, Switzerland, to coincide with the Retrospective
Exhibition of the works of the Italian painter, Pierro Dorazio.
He has served as a Trustee of Fight for
Sight, London and of the Minerva Foundation, Berkeley, California.
He was a member of the National Society
Council of France from 1998 to 2002 and is a member of the
Board of Scientific Governors of The Scripps Research Institute,
California.
He was Editor of The Philosophical Transactions
of the Royal Society, Biological Sciences and has served on
the editorial boards of several other journals specialized
in neurobiology.
He is a Fellow of the Royal Society, a foreign
member of the American Philosophical Society, Fellow of the
Academy of Medical Sciences (London), a member of the Academia
Europeae and of the European Academy of Sciences and Arts.
His Prizes include the Minerva Foundation
Prize, The LVMH Science pour l’art Prize, the Rank Prize
in opto-electronics, The Electronic Imaging Award, the Koetser
Prize and the King Faisal International Prize in Biology.
Scientific achievements
Zeki's scientific achievements include:
-Co-discovery of the motion area in the
brain, area V5 (also called area MT), in parallel with American
scientists John Allman and Jon Kaas.
-Ardent defender of functional specialization
of brain regions.
-Finding neurons in a part of the monkey
visual system that would respond only when a particular colour,
rather than a particular wavelength, was in their receptive
fields. For example, he showed that a red-sensitive neuron
would continue to respond to a red stimulus, even when it
was illuminated mainly by green light.
-Use of imaging techniques to identify
the location of a region of the human brain that shows color-biased
response properties.
-Studying the neural correlctive mental
states, such as love Life outside of science
Semir Zeki lists his hobbies as visual arts,
reading (especially about the darker side of man), music (especially
opera) and deep sleep.
