Schizophrenia is one of the most common mental disorders, however it is difficult to detect and can remain undiagnosed for years. It is believed that information if a patient is ill can be extracted from EEG signals recorded using electrodes located at the patient scalp. In the paper we postulate that a network of chemical oscillators can process recorded signals and help to diagnose a patient. In order to verify our approach we investigated the network functionality on a small dataset of EEG signals recorded from 45 ill and 39 healthy patients. We optimized a network formed by just six interacting oscillators using an evolutionary algorithm and obtained over 82% accuracy of schizophrenia detection on the training dataset.
