Ways are being investigated for identifying paths
along which EEG (electroencephalograph) signals
travel through the brain. It is believed that such
knowledge is helpful in the localization of brain
tumors and the detection of different disorders,
such as schizophrenia, seizures, or ADD/ADHD. One
approach being pursued is to employ the complex
coherence function to multi-channel EEG data. Another
approach is to study the phase synchronization
of EEG data, which then facilitates topographical
mapping of brain signals in terms of synchronization
strength.
