Neurotechnology: Current Developments and Ethical Issues
Neurotechnology is a fascinating and, at the same time, controversial field as one of its goals is to directly “wire up” human brains to machines. We should indeed expect to encounter such hybrid brain-machine systems more frequently in the future. These technical components are electrodes, computers, or intelligent prostheses. They are meant to either record signals from the brain and “translate” them into technical control commands, or to manipulate brain activity by applying electrical or optical stimuli. Closed-loop interactions of readout and stimulation systems (control circuits) are subject of current research as well.
