	Marcelo Magnasco: Sparse time-frequency representations and the neural coding of sound - Redwood Center for Theoretical Neuroscience Talk given for the Redwood Center for Theoretical Neuroscience on February 13, 2008. Speaker is Marcelo Magnasco of Rockefeller University. Abstract. Auditory neurons preserve exquisite temporal information about sound features, but we do not know how the brain uses this information to parse the rapidly changing sounds of the natural world. A simple argument for making effective use of temporal information in the auditory nerve leads us to consider the reassignment class of time-frequency repres...
