Zusammenfassung
Synchronous high frequency activity of the electroencephalogram (EEG) in the Gamma band range (30–100Hz) has been proposed to play an important role in integrating parallel neuronal activity, the so-called 'binding' of distributed brain activities. The early auditory evoked gamma-band response (GBR) typically appears around 50ms after stimulus presentation and is closely related to selective attention. Patients with Schizophrenia seem to have deficits in the generation of coherent, synchronised oscillation in the gamma-band range. This might be due to a dysfunction of neural microcircuits, especially of the inte…
