Various methods and systems are provided for cerebral diagnosis. In one example, among others, a method includes obtaining EEG signals from sensors positioned on a subject； conditioning data from the EEG signals to remove artifacts； generating a cerebral network model based at least in part upon the conditioned data； determining network features based upon the cerebral network model； and determining a cerebral condition of the subject based at least in part upon the network features. In another example, a method includes determining a recording condition of a positioned EEG sensor and providing an indication of an unacceptable recording condition of the EEG sensor. In another example, a system includes an EEG recording module to acquire signals； a signal conditioning module to condition signal data； a signal analysis module to determine signal features and cerebral network features； and a condition classification module to determine a cerebral condition of the subject.
