Schematic of Neuromodulation technology. A block schematic of neuromodulation technology highlights common components: the programmer, typically a clinician or a patient device, provides an interface for the user to connect with the pulse generator, which serves as a power source, and delivers specifically patterned waveforms to the neural target via the electrodes. The dashed lines represent the closed-loop paradigm now emerging in the field which integrates signals from relevant sensors to provide feedback.
