...second was the discovery of spatial organization in specific parts of the brain. At the surface of the brain, called the cortex, sheets of tissue preserve images from the retina of the eye in patterns of activity in neural cells...
...third was the development of brain-scanning technologies, specifically PET (positron emission tomography), which can determine if patterns of neural activity in the brain are present during certain tasks. Using such technology, researchers have found that spatially organized parts of the brain are active in different places depending on the size of objects being viewed...
More importantly, when comparing neural activity from the listening session and the imagery session, Kosslyn and his collaborators found evidence of activity in areas 17 and 18 of the brain, parts which are known to be spatially organized. Activity was found to vary depending on the size of the image, a relationship which parallels that found when eyes normally view an object...
...they complement each other; how one's ability to handle stress, for instance, affects the ability to concentrate and put intelligence to use. Among the ingredients for success, researchers now generally agree that IQ counts for about 20%; the rest depends on everything from class to luck to the neural pathways that have developed in the brain over millions of years of human evolution...
...unprecedented interdisciplinary initiative, four new undergraduate concentration tracks--the first of their kind--have already attracted over 100 Harvard undergraduates, who will study topics ranging from neural networks to addiction to primate social psychology...
