Diagram of the thalamic stimulation parameters before, during, and after ischemia. Each horizontal line is a cluster of 20-test pulses (1 Hz). Upon ischemia (T=0), a stimulation cluster was administered every minute for 15 minutes. Subsequently, the interval between clusters was increased to 5 minutes for the duration of 45 minutes (up to 1 hour post stroke). From 1 hour to 3 hours post stroke, each cluster was administered every 15 minutes.
