The annual INCF Congress provides a meeting place for researchers in this emerging field. The INCF Neuroinformatics Congress welcomes researchers in all fields related to neuroinformatics, including data- and knowledge-bases of the nervous system from molecular to behavioral levels; tools for the acquisition, analysis, and visualization of nervous system data; and theoretical, computational, and simulation environments for modeling the brain. The 2013 INCF Neuroinformatics Congress will take place August 27-29 at the Karolinska Institutet, in Stockholm, Sweden.
