Cortical connectivity in high-frequency beta-rhythm in schizophrenics with positive and negative symptoms
Graduate studies at Western
Behavioral and Brain Sciences 26 (1):105-106 (2003)
|Abstract||In chronic schizophrenic patients with both positive and negative symptoms (see Table 1), interhemispheric connections at the high frequency beta2-rhythm are absent during cognitive tasks, in contrast to normal controls, who have many interhemispheric connections at this frequency in the same situation. Connectivity is a fundamental brain feature, evidently greatly promoted by the NMDA system. It is a more reliable measure of brain function than the spectral power of this rhythm.|
