Fig 2. The α–peak depend on synaptic time constants.

(A) Increasing β_e increases the α–power peak frequency. The red color shows the region β_e < 40 Hz where no spectral power peak in the α–range can be observed. (B) The α–peak frequency remains more or less unchanged by the increase in α_e. (C) The increase in β_i has an insignificant effect on α–power peak frequency, whereas (D) it remains unaffected by the increase in α_i. In all panels, unchanged parameters are taken from Table 1.
