Fig. 6From: An Interactive Channel Model of the Basal Ganglia: Bifurcation Analysis Under Healthy and Parkinsonian ConditionsOscillatory population activity in isolated channel model. Population activity over time for three points in region C, showing periodic pauses (top), bursts of high activity (bottom) and roughly even oscillation between high and low activity (middle). As in previous figures, the red and blue lines represent the activity of the STN (x(t)) and GPe (y(t)), respectivelyBack to article page
