The left shows thousands of dye-loaded cells in the mouse auditory cortex over a large area. The right shows the preferred frequency of many cells, and shows that neighboring cells can have dramatically different frequency preference.
New research shows our brains are a lot more chaotic than previously thought, and that this might be a good thing. Neurobiologists at the University of Maryland have discovered information about how the brain processes sound that challenges previous understandings of the auditory cortex that suggested an organization based on precise neuronal maps. In the first study of the auditory cortex conducted using advanced imaging techniques, Patrick Kanold, Assistant Professor of Biology, Shihab Shamma, Professor of Electrical and Computer Engineering, and Sharba Bandyopadhyay, post-doctoral.
