Super soldiers equipped with neural implants, suits that contain biosensors, and thought scans of detainees may become reality sooner than you think.

In this video taken from the show "Conversations from Penn State", Jonathan Moreno discusses the ethical implications of the applications of neuroscience in modern warfare.

Moreno is David and Lyn Silfen professor and professor of medical ethics and the history and sociology of science at the University of Pennsylvania and was formerly the director of the Center for Ethics at the University of Virginia. He has served as senior staff member for two presidential commissions and is an elected member of the Institute of Medicine of the National Academies.

The BSI-Toyota Collaboration Center (BTCC) is developing a wheelchair that can be navigated in real-time with brain waves. The brain-controlled device can adjust itself to the characteristics of each individual user, thereby improving the efficiency with which it senses the driver's commands. That way, the driver is able to get the system to learn his/her commands (forward/right/left) quickly and efficiently; the system boasts an accuracy rate of 95%.

Persons suffering from mild dementia can benefit from a form of cognitive prosthetic which can be used to assist them with their day to day activities. Within our current work we are aiming to develop a successful user-validated cognitive prosthetic for persons with mild dementia. We have devised a three phased waterfall methodology to support our developments. Based on the evaluation of the first of these phases which involved the processes of user requirements gathering, prototype development and evaluation of in situ deployment of the technology we have been able to guide the technical development within the second phase of our work. Within this paper we provide an overview of the first phase of our methodology and demonstrate how we have used the results from this to guide the second phase of our work, especially with regards to the notion of personalisation.

The development of brain-machine interface neuroprosthetic devices.

Neurotherapeutics. 2008 Jan;5(1):137-46

Authors: Patil PG, Turner DA

The development of brain-machine interface technology is a logical next step in the overall direction of neuroprosthetics. Many of the required technological advances that will be required for clinical translation of brain-machine interfaces are already under development, including a new generation of recording electrodes, the decoding and interpretation of signals underlying intention and planning, actuators for implementation of mental plans in virtual or real contexts, direct somatosensory feedback to the nervous system to refine actions, and training to encourage plasticity in neural circuits. Although pre-clinical studies in nonhuman primates demonstrate high efficacy in a realistic motor task with motor cortical recordings, there are many challenges in the clinical translation of even simple tasks and devices. Foremost among these challenges is the development of biocompatible electrodes capable of long-term, stable recording of brain activity and implantable amplifiers and signal processors that are sufficiently resistant to noise and artifact to faithfully transmit recorded signals to the external environment. Whether there is a suitable market for such new technology depends on its efficacy in restoring and enhancing neural function, its risks of implantation, and its long-term efficacy and usefulness. Now is a critical time in brain-machine interface development because most ongoing studies are science-based and noncommercial, allowing new approaches to be included in commercial schemes under development.

IEEE Spectrum Online has a special report on the current state of prosthethic arm development, including the latest on Dean Kamen's "Luke Arm" which is being funded by DARPA. There's also an amazing video showing the arm in action.

Researchers at Northwestern University, in Chicago, have shown that transplanting the nerves from an amputated hand to the chest allows patients to feel hand sensation there.

The findings are the first step toward prosthetic arms with sensors on the fingers that will transfer tactile information from the device to the chest, making the wearer feel as though he or she has a real hand.
