Living with three arms
Via VRoot
(From Virtual Worldlets)
Virtual Reality is just beginning to head down the full body sensation reproduction path. We are at the very early stages of being able to recreate parts of the physical form, entirely in the virtual. This is a concept which is likely to have very a profound effect upon how we deal with the world around us.
At the moment, VR technology in reproducing virtual limbs is limited to a single limb at a time. This is done by mimicking the movements of the user's physical limb by reading the signals sent down the brainstem, translating and implementing them, as opposed to monitoring the movement of the arm and duplicating that. This is both faster than mimicking the movement observationally, and also allows the technique to work if the user has no physical arm to mimic, so long as the brain is capable of controlling one - e.g., quadriplegics, limb amputees.

New Scientist reports about a new Kung-fu computer game that allows the user to deliver real kicks:
Kick Ass Kung Fu lets players fight onscreen enemies using real kicks, punches, head-butts or by wielding any improvised weapon they choose. A video camera captures their movements from one side and superimposes a two-dimensional silhouette of them onto a computer screen. A computer then translates the silhouette's moves into real-time computerised kicks and punches, enabling a player to take on virtual opponents.

Virtual reality immersion method of distraction to control experimental ischemic pain
Virtual reality immersion method of distraction to control experimental ischemic pain.
Isr Med Assoc J. 2006 Apr;8(4):261-5
Authors: Magora F, Cohen S, Shochina M, Dayan E
BACKGROUND: Virtual reality immersion has been advocated as a new effective adjunct to drugs for pain control. The attenuation of pain perception and unpleasantness has been attributed to the patient's attention being diverted from the real, external environment through immersion in a virtual environment transmitted by an interactive 3-D software computer program via a VR helmet. OBJECTIVES: To investigate whether VR immersion can extend the amount of time subjects can tolerate ischemic tourniquet pain. METHODS: The study group comprised 20 healthy adult volunteers. The pain was induced by an inflated blood pressure cuff during two separate, counterbalanced, randomized experimental conditions for each subject: one with VR and the control without VR exposure. The VR equipment consisted of a standard computer, a lightweight helmet and an interactive software game. RESULTS: Tolerance time to ischemia was significantly longer for VR conditions than for those without (P < 0.001). Visual Analogue Scale (0-10) ratings were recorded for pain intensity, pain unpleasantness, and the time spent thinking about pain. Affective distress ratings of unpleasantness and of time spent thinking about pain were significantly lower during VR as compared with the control condition (P< 0.003 and 0.001 respectively). CONCLUSIONS: The VR method in pain control was shown to be beneficial. The relatively inexpensive equipment will facilitate the use of VR immersion in clinical situations. Future research is necessary to establish the optimal selection of clinical patients appropriate for VR pain therapy and the type of software required according to age, gender, personality, and cultural factors.

Cognitive Computing
Nicholas Nova quotes an interview of Dharmendra Modha, chair of the Almaden Institute at IBM’s San Jose and IBM’s leader for cognitive computing, who claims a language shift from the previsouly so-called “Artifical Intelligence” to “Cognitive Computing”:
Q: Why use the term “cognitive computing” rather than the better-known “artificial intelligence”?
A: The rough idea is to use the brain as a metaphor for the computer. The mind is a collection of cognitive processes—perception, language, memory, and eventually intelligence and consciousness. The mind arises from the brain. The brain is a machine—it’s biological hardware.
Cognitive computing is less about engineering the mind than it is the reverse engineering of the brain. We’d like to get close to the algorithm that the human brain [itself has]. If a program is not biologically feasible, it’s not consistent with the brain.

Robotic Action Painter
RAP (Robotic Action Painter) is a new generation of painting robots designed for Museum or long exhibition displays. It is completely autonomous and need very little assistance and maintenance. RAP creates it's own paintings based on an artificial intelligence algorithm, it decides when the work is ready and signs in the right bottom corner with its distinctive signature. The algorithm combines initial randomness, positive feedback and a positive/negative increment of 'color as pheromone' mechanism based on a grid of nine RGB sensors. Also the 'sense of rightness' - to determine when the painting is ready - is achieved not by any linear method, time or sum, but through a kind of pattern recognition system.

New implantable device system for stroke rehabilitation
Via Medgadget
The US company Northstar Neuroscience is developing an implantable device system intended to enhance neuroplasticity and recovery of function in patients status post stroke.
![](http://gaggio.blogspirit.com/images/medium_7543613.2.jpg)
From the company's website:
Following a stroke, the only proven treatment currently available for patients with hemiparesis (motor deficits) or aphasia (speech deficits) is rehabilitative therapy. Unfortunately, many patients do not achieve satisfactory functional improvement from rehabilitative therapy. There is considerable evidence that the brain can undergo significant repair and recovery after an injury such as a stroke by a process termed neuroplasticity.As reported in numerous scientific publications, neuroplasticity involves the recruitment of existing alternative neural pathways and the development of new synaptic connections, i.e., reorganization of the brain circuitry. Within hours after a stroke, the brain will begin to recruit existing alternative neural pathways in an attempt to meet functional demands. Over time and with use, there is an increase in the density of connections between the neurons that comprise these neural pathways. However, natural gains in motor recovery and speech generally plateau within several months after a stroke, with many stroke survivors achieving only minimal recovery of function...
Together, we have demonstrated that cortical stimulation of the healthy brain tissue adjacent to the "stroke," in combination with rehabilitation, enhances motor recovery and suggests that cortical stimulation for stroke patients may facilitate neuroplasticity...
The Northstar Stroke Recovery System is comprised of the following components:
-- Implantable pulse generator (IPG) - an electrical stimulator that is implanted in the pectoral (upper chest) area.
-- Cortical stimulation lead - an electrode connected to the IPG, which is used to deliver stimulation to the cortex. The electrode is placed on top of the dura, which is the membrane that covers the brain's surface.
-- Programming system - a handheld computer attached to a programming device which allows communication with the implanted IPG device. This system allows the clinician to turn the device on/off and to set/modify stimulation parameters

Virtual reality is commonly the stuff of science fiction — but the real-world applications made possible by using computer simulations inside a virtual reality environment are as tangible as diapers and oil wells.
The soon-to-open Louisiana Immersive Technologies Enterprise will make any number of research and business applications possible, said Carolina Cruz-Neira, the newly hired chief scientist at LITE.
Cruz-Neira gave an overview of LITE on Thursday at the TechSouth technology summit.
At the heart of LITE is a supercomputer and 6-sided (hexagonal) visual immersion cave. The supercomputer can process and simulate an enormous amount of data, then project that visual data onto the screens of the cave, which serves as a virtual reality environment that allows researchers to better understand that data...

Warriors of the future will 'taste' battlefield
Via CNN
PENSACOLA, Florida (AP) -- In their quest to create the super warrior of the future, some military researchers aren't focusing on organs like muscles or hearts. They're looking at tongues.
By routing signals from helmet-mounted cameras, sonar and other equipment through the tongue to the brain, they hope to give elite soldiers superhuman senses similar to owls, snakes and fish.
Researchers at the Florida Institute for Human and Machine Cognition envision their work giving Army Rangers 360-degree unobstructed vision at night and allowing Navy SEALs to sense sonar in their heads while maintaining normal vision underwater -- turning sci-fi into reality.
The device, known as "Brain Port," was pioneered more than 30 years ago by Dr. Paul Bach-y-Rita, a University of Wisconsin neuroscientist. Bach-y-Rita began routing images from a camera through electrodes taped to people's backs and later discovered the tongue was a superior transmitter...

Cardiac responses induced during thought-based control of a virtual environment
Cardiac responses induced during thought-based control of a virtual environment.
Int J Psychophysiol. 2006 Apr 25;
Authors: Pfurtscheller G, Leeb R, Slater M
Cardiac responses induced by motor imagery were investigated in 3 subjects in a series of experiments with a synchronous (cue-based) Brain-Computer Interface (BCI). The cue specified right hand vs. leg/foot motor imagery. After a number of BCI training sessions reaching a classification accuracy of at least 80%, the BCI experiments were carried out in an immersive virtual environment (VE), commonly referred as a "CAVE". In this VE, the subjects were able to move along a virtual street by motor imagery alone. The thought-based control of VE resulted in an acceleration of the heart rate in 2 subjects and a heart rate deceleration in the other subject. In control experiments in front of a PC, all 3 subjects displayed a significant heart rate deceleration of the order of about 3-5%. This heart rate decrease during motor imagery in a normal environment is similar to that observed during preparation for a voluntary movement. The heart rate acceleration in the VE is interpreted as effect of an increased mental effort to walk as far as possible in VE.

Steady-state somatosensory evoked potentials
Steady-state somatosensory evoked potentials: suitable brain signals for brain-computer interfaces?
IEEE Trans Neural Syst Rehabil Eng. 2006 Mar;14(1):30-7
Authors: Müller-Putz GR, Scherer R, Neuper C, Pfurtscheller G
One of the main issues in designing a brain-computer interface (BCI) is to find brain patterns, which could easily be detected. One of these pattern is the steady-state evoked potential (SSEP). SSEPs induced through the visual sense have already been used for brain-computer communication. In this work, a BCI system is introduced based on steady-state somatosensory evoked potentials (SSSEPs). Transducers have been used for the stimulation of both index fingers using tactile stimulation in the "resonance"-like frequency range of the somatosensory system. Four subjects participated in the experiments and were trained to modulate induced SSSEPs. Two of them learned to modify the patterns in order to set up a BCI with an accuracy of between 70% and 80%. Results presented in this work give evidence that it is possible to set up a BCI which is based on SSSEPs.
