The Allen Institute for Brain Science, a division of the Allen Institute, today announced new data aimed at helping researchers understand the various types of cells in the brain and how cells compute visual information. Joining these new data is a software toolkit for building models of the neuronal networks making up the brain more easily and more reproducibly. Scientists around the world can find these resources at the newly redesigned Allen Brain Atlas portal and use them to study basic questions about brain structure and function, as well as brain diseases and disorders.
