Power spectral frequency of the Golgi cells (GoCs) population spike timing histograms (PSTHs) in the presence of varying mossy fiber (MF) input rates and parallel fiber (PF) synaptic weights. Network responses of the GoC layer with (red) and without gap junctions (blue) between GoCs. Power spectral density for each PF strength and MF input rate (A to F) for the regular network model of length 1.5 mm. X axis: Oscillation frequency (Hz). The y axis = PF synaptic weight (%), z axis = normalized power. MF rate at (A) 1 Hz, (B) 5 Hz, (C) 10 Hz, (D) 20 Hz, (E) 40 Hz, (F) 70 Hz.
