For the first time ever, a paralyzed man can move his fingers and hand with his own thoughts thanks to an innovative partnership between The Ohio State University Wexner Medical Center and Battelle.
Ian Burkhart, a 23-year-old quadriplegic from Dublin, Ohio, is the first patient to use Neurobridge, an electronic neural bypass for spinal cord injuries that reconnects the brain directly to muscles, allowing voluntary and functional control of a paralyzed limb. Burkhart is the first of a potential five participants in a clinical study.
I have just accidentally discovered a video with my introduction to a Brain-Computer Interfaces. The PPT slides are available here
We need to understand both HCI as well as BCI, such that the two not be treated separately. Dr. Mark Sagar is known for being a two-time Oscar winner for his work with Weta Digital. Inspired by the potential for artificial intelligence he now heads research in this area at the University of Auckland Bioengineering Institute.
When it comes to your moods, decisions and behaviour, the brain in your head is not the only one doing the thinking
IT’S been a tough morning. You were late for work, missed a crucial meeting and now your boss is mad at you. Come lunchtime you walk straight past the salad bar and head for the stodge. You can’t help yourself - at times of stress the brain encourages us to seek out comfort foods. That much is well known. What you probably don’t know, though, is that the real culprit may not be the brain in your skull but your other brain.
Yes, that’s right, your other brain. Your body contains a separate nervous system that is so complex it has been dubbed the second brain. It comprises an estimated 500 million neurons - about five times as many as in the brain of a rat - and is around 9 metres long, stretching from your oesophagus to your anus. It is this brain that could be responsible for your craving under stress for crisps, chocolate and cookies.
Embedded in the wall of the gut, the enteric nervous system (ENS) has long been known to control digestion. Now it seems it also plays an important role in our physical and mental well-being. It can work both independently of and in conjunction with the brain in your head and, although you are not conscious of your gut “thinking”, the ENS helps you sense environmental threats, and then influences your response. “A lot of the information that the gut sends to the brain affects well-being, and doesn’t even come to consciousness,” says Michael Gershon at Columbia-Presbyterian Medical Center, New York.
A predictive planning organization within the federal government, compiled these and other emerging technology predictions through consulting with experts in a project called MetaScan 3: Emerging Technologies. As part of the report, the group partnered with futurist and data visualization specialist Michell Zappa and his organization Envisioning.
A #glutamate free diet reported to remove #autism symptoms. As glutamate is one of the most widespread excitatory neurotransmitter, misregulation of this molecule may cause disorders of the neural spectrum. Trying to remove Sodium Glutamate, MSG (Е621, Е631) from daily diet positively effect health state. Industrial food manufacturers market and use MSG as a flavor enhancer because it balances, blends and rounds the total perception of other tastes.
In physics, resonance is the tendency of a system to oscillate with greater amplitude at some frequencies than at others. Frequencies at which the response amplitude is a relative maximum are known as the system’s resonant frequencies, or resonance frequencies. At these frequencies, even small periodic driving forces can produce large amplitude oscillations, because the system stores vibrational energy. Resonance occurs when a system is able to store and easily transfer energy between two or more different storage modes (such as kinetic energy and potential energy in the case of a pendulum)
Similarly, one could conjecture, if we force brain dynamics with a magical frequency or otherwise properly designed waveform we may entrain and amplify certain rhythms
Although nobody was really asking for it at the time, these thoughts provided an important element in the decision to create a device capable of stimulating and recording EEG simultaneously. Could we use it to study such resonance effects? More generally, could we envision open or closed-loop applications that would allow for “smart” EEG-driven stimulation?
A related phenomenon is stochastic resonance, which may play a role in the effect of tRNS. Basically, adding noise to a non-linear system may make it more likely to resonate. This is a phenomenon in the realm of non-linear dynamics (and the brain is definitely non-linear!).
Working full-time on trying to emulate neural connectivity patterns, I still don’t really know If I’m contributing to a right direction of human development. Apart from valuable opportunities in health care, trans-humanism as depicted in the “transcendence” film poses a real threats on our relationships as we know them.
On the 2nd of February 2014 we launched an experimental project called #Aiutico as a part of our User Research program to understanding emerging behaviors of the artistically-conscious audience.
