Ethics and Neural Prosthetics
Society, even outside of the field of science and medicine, is faced with ethical dilemmas every day in which people are forced to take a stance and make difficult decisions. However, the question becomes where do these decisions come from? What are ethics? And is there bias involved in the drawing of these ethical conclusions? Philosophers have been pondering these questions for centuries and ...
متن کاملCognitive neural prosthetics
The cognitive neural prosthetic (CNP) is a very versatile method for assisting paralyzed patients and patients with amputations. The CNP records the cognitive state of the subject, rather than signals strictly related to motor execution or sensation. We review a number of high-level cortical signals and their application for CNPs, including intention, motor imagery, decision making, forward est...
متن کاملCortical neural prosthetics.
Control of prostheses using cortical signals is based on three elements: chronic microelectrode arrays, extraction algorithms, and prosthetic effectors. Arrays of microelectrodes are permanently implanted in cerebral cortex. These arrays must record populations of single- and multiunit activity indefinitely. Information containing position and velocity correlates of animate movement needs to be...

6 This article provides an overview of the physical components that 7 tend to be common to all neural prosthetic systems. It emphasizes 8 the biophysical factors that constrain the sophistication of those 9 interfaces. Specific applications to neural prosthetic systems for 10 sensory replacement and motor control are covered in PROSTHET11 ICS, SENSORY SYSTEMS and PROSTHETICS, MOTOR CONTROL, re1...
متن کاملCognitive control signals for neural prosthetics.
Recent development of neural prosthetics for assisting paralyzed patients has focused on decoding intended hand trajectories from motor cortical neurons and using this signal to control external devices. In this study, higher level signals related to the goals of movements were decoded from three monkeys and used to position cursors on a computer screen without the animals emitting any behavior...
