It's an interesting contradiction. In some contexts, EEG coherence is seen as a Very Good Thing, and in others as a Very Bad Thing. Brain-damaged individuals often show EEG coherence, presumably because the activity of the brain has not differentiated in a healthy manner. Epileptics show EEG coherence due to abnormally firing neurons associated with siezures. Here's a study that suggests both good and bad in the same test subjects. They lack healthy coherence in one part of the brain and have unhealthy coherence in another part: http://tinyurl.com/fk7d2 1: Clin EEG Neurosci. 2005 Jan;36(1):42-8.

Department of Psychiatry and Neurobiology, Graduate School of Medical Science, Kanazawa University, Japan. [EMAIL PROTECTED] To investigate the functional abnormalities in the central nervous system (CNS) of patients with panic disorder (PD), we compared the electroencephalography (EEG) coherence values in 18 never-medicated PD patients with those in age-matched normal control subjects, and examined the relationships between EEG coherence values and both the duration of disease and the severity of panic attacks. EEG data were recorded in the resting state. The PD patients had lower coherence values with significant differences in F3-F4, C3-C4, P3- P4, F7-T5, and F8-T6. There were positive correlations for the higher alpha band between coherence values and both the duration of disease and the severity of panic attacks. These findings provide further evidence that PD patients have a lower degree of inter- hemispheric functional connectivity in the frontal region and intra-hemispheric functional connectivity in the bilateral temporal region, and that chronic condition or frequent panic attacks in PD patients may be related to the pathophysiological CNS changes. ------------------------ Yahoo!
