AB  - Interactions between different cortical rhythms, such as slow and fast 
      oscillations, have been hypothesized to underlie many cognitive functions. In 
      patients diagnosed with schizophrenia, there is some evidence indicating that the 
      interplay between slow and fast oscillations might be impaired or disrupted. In 
      this study, we investigated multiple oscillatory interactions in schizophrenia 
      using a novel approach based on information theory. This method allowed us to 
      investigate interactions from a new perspective, where two or more rhythm 
      interactions could be analyzed at the same time. We calculated the mutual 
      information of multiple rhythms (MIMR) for EEG segments registered in resting 
      state. Following previous studies, we focused on rhythm interactions between 
      theta, alpha, and gamma. The results showed that, in general, MIMR was higher in 
      patients than in controls for alpha-gamma and theta-gamma couplings. This finding 
      of an increased coupling between slow and fast rhythms in schizophrenia may 
      indicate complex interactions in the Default Mode Network (DMN) related to 
      hyperactivation of internally guided cognition.
