Stimulus-Dependent State Transition between Synchronized Oscillation and Randomly Repetitive Burst in a Model Cerebellar Granular Layer
Figure 8
OI and PI for the present model in the space spanned by [Mg2+] and IMF.
The abscissa and ordinate represent [Mg2+] and IMF, respectively. Values of OI are shown in the brightness of the green color, where the darkest shade indicates OI = 0 and brightest shade indicates OI = 1. Values of PI are shown by the brightness of the red color such that the darkest shade indicates PI = 0 and the brightest shade indicates PI = 1. Greenish or reddish domains indicate that the network exhibited synchronized oscillatory states or POT-representing states, respectively. Eight typical points are picked out from this parameter space. The white lines represent average firing rates of grcs of 1, 5, 10, 15, 20, 30 and 40 Hz.
