JCN is a journal devoted to research in systems neuroscience—understanding communication within systems of neurons, and the relationship of these to function, development, plasticity, degeneration, and repair. Molecular, anatomical, physiological, pharmacological, and behavioral methods are used to investigate neuronal systems, giving rise to the journal’s interdisciplinary scope and broad appeal. JCN covers both basic research in systems neurosciences and clinical aspects of neurology, neuropathology, psychiatry, or psychology.
