Core Tip

Core Tip: There have been identified five independent components, on the level of brain signals, which are significantly modulated by clinical diagnostic scales adapted to functional magnetic resonance imaging paradigm. Those results may help potentially to define patterns of activations which differ between patients with depression and patients with schizophrenia.
