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.
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.
The current drug development cycle is too costly, takes too long, and fails more often than it succeeds. Diseases go untreated and patients who need therapy are not receiving any relief. In the TED Talk Body parts on a chip Geraldine Hamilton discusses her method to test drugs outside the body. Hamilton is attacking the problem of drug testing before human clinical trials. Testing human cells in petri dishes don’t give ideal results because the environment is totally different than a human body. Animal testing often fail to predict what will happenin humans. Her solution is to use human cells and keep them happy outside the human body. Inspiration comes from the manufacture of computer chips to build the chips. Three channels exist within the chips, beginning with a thing membrane in the center that holds the human cells. Mechanical forces can then be applied to the outside of these cells to simulate tension, compression, temperature changes or fatigue. Channels exist above and below the cell to circulate air and blood.
