FIGURE 2.1. Elements of a system for brain interfacing.


Elements of a system for brain interfacing. (A) Implanted components include an electrode or electrode array, lead wire or lead cable, and either a percutaneous connection or an implanted electronics package. The implanted electronics may be a pulse generator for instances of brain stimulation or signal conditioners (amplifiers, filters) and signal telemeters for instances of brain recording. (B) The tissue response around the electrode(s) can result from passive mechanical or chemical factors, from activity dependent changes in the excitability of neurons, and/or from the products of electrochemical products at the electrode–tissue interface, and can lead to changes in device functionality.
