1. 1 Neuro-Electronic Interfacing 1. 1. 1 Nervous System Communication in the(human) bodyand the interaction with the environment is controlled by the nervous system. It can be divided into a central part, which - cludes the spinal cord, brainstem, cerebellum, and cerebrum, and a peripheral part, which includes all neuronal tissue outside the central part (Martini 2001).
