Date posted: 17/03/2008 In the first visualisation study of such, University of Texas neuroscientists have demonstrated how populations of nerve cells in the visual cortex adapt to new images, showing that a network of sensory neurons changed its encoding properties to properly represent the environment. They measured the effects of visual stimulation on the responses of multiple neurons in animals. A brief exposure to a fixed stimulus caused changes in the degree of cooperation between individual neurons and increased the efficiency with which the population of cells encoded information. While their study focused on how neuronal populations adapt to visual stimulation, the same could hold true for other senses - hearing, smell, taste and touch, senior author Valentin Dragoi, Ph.D., assistant professor of neurobiology and anatomy said. ?We?re trying to understand how a network of sensory neurons changes its encoding properties to properly represent the environment. Our results may have general implications for sensory and motor coding in a variety of brain areas.?
