Figure 4From: A mathematical model of dysfunction of the thalamo-cortical loop in schizophreniaBifurcation diagram. Bifurcation diagram in the (K T -x C )-plane. The coupling strength from the cortex to the thalamus has been set to K C =1.2 and the coupling strength K T from the thalamus to the cortex is varied; ω ~ C =3 Hz and ω ~ T =7 Hz. Red line: stable fixed points (x F ), black line: unstable fixed points; green filled circles represent the maximum and minimum of stable periodic orbits (x PS ) while the blue circles represent the maximum and minimum of unstable periodic orbits (x PU ). Bifurcation points, i.e. the fold limit cycle bifurcation (FLB) at K T FLB and the Hopf-bifurcation (HB) at K T HB are marked with vertical blue lines. The light blue box represents the parameter region where the initially synchronized system desynchronizes in finite time (like in Figure 1).Back to article page
