This is the thirteenth annual meeting of an interdisciplinary conference addressing a broad range of research approaches and issues involved in the field of computational neuroscience. These meetings bring together experimental and theoretical neurobiologists along with engineers, computer scientists, physicists and mathematicians interested in the functioning of biological nervous systems. Peer reviewed papers are presented all related to understanding how the nervous systems compute. As in previous years, CNS*2004 will equally emphasize experimental, model- based and more abstract theoretical approaches to understanding neurobiological computation.
