Figure 5From: Development of a multi-electrode array for spinal cord epidural stimulation to facilitate stepping and standing after a complete spinal cord injury in adult ratsSchematic of the stimulator circuit board. Stimulator circuit used describing the use of the Pulse Width Modulation (PWM) to generate the required voltage between Stim+ and Stim-. Mode controls current mode vs. voltage mode, and the CurrSense signals allow the stimulating host computer to measure the drawn current.Back to article page
