Figure 4. Dynamical regimes of a dominantly inhibitory neural population.

Contour map of the mean field amplitude calculated for ratio n = 2.5 and mean m = 0 are displayed as function of connectivity strengths K ₁₁, K ₁₂ and strength of dispersion σ. Four different regions with specific oscillatory behavior are identified. Examples of time series for neurons with low (black) and high (red) value of the I parameter are given.
