The human brain can be studied as a hierarchy of complex networks on different temporal and spatial scales. On each scale, from gene, protein, synapse, neuron and microcircuit, to area, pathway and the whole brain, many advances have been made with the development of related techniques. Brain network studies on different temporal and spatial scales are booming. However, such studies have focused on single levels, and can only reflect limited aspects of how the brain is formed and how it works. To this end, China has proposed the concept of the brainnetome and several related programs/projects have been launched in the country. Brainnetome includes techniques on different scales: the brainnetome atlas and methods of brain network analysis. Alzheimer’s disease and schizophrenia will be taken as examples to show how the brainnetome can be studied in neurological and psychiatric disorders…
