Picking our Brains: Why Are some People Smarter?

Images created by Paul Thompson, professor of neurology and a member of the UCLA Laboratory of Neuro Imaging (LONI), appeared in a March 31 New Scientist pictorial that showed the human brain’s white matter, largely composed of the fatty myelin sheaths around neurons that reveals the brain's connections. LONI colleagues David Shattuck, associate professor of neurology, and Arthur Toga, lab director and professor of neurology, were cited. Thompson was also quoted in an accompanying article on the integrity of the brain’s white matter and its possible connection to creativity. He also commented in an April 4 New Scientist article about a possible correlation between IQ and the quality of myelin around neuron fibers.
