The black technology in science fiction movies, the depth of the brain and the degree of arrogance and coolness are impressive. As an imaginary, these future technologies are also meeting the development direction of human future science and technology while satisfying the visual enjoyment of the people who eat melons.
In early 2014, Dr. Edward Boyden, a professor of brain cognitive science and bioengineering at the Massachusetts Institute of Technology's McGovern Institute, opened a crazy brainstorm with many great gods. The theme of brainstorming is to explore "all possible ways to artificially stimulate brain neurons."
This group of top scientists may also have seen more sci-fi movies. At the same time, various brains opened up. The results of the discussion covered almost all kinds of energy in nature, such as electric fields, magnetic fields, ultrasonic waves, light waves, etc., and listed a long List!
Don't think that scientists are brainstorming, just like you see popcorn movies, it's over. This group of scientists really tried it according to the brain hole they opened!
In December 2016, a team led by Dr. Edward Boyden and MIT neuroscientist Li-Huei Tsai published a super-subversive study in Nature and attracted widespread attention. The article pointed out that the use of special frequency LED lights can greatly reduce the amyloid beta protein in the brain of Alzheimer's mice!
After half a lapse, MIT's Edward S. Dr. Boyden and Dr. Li-Huei Tsai collaborated with scientists at the Beth Israel Deaconess Medical Center to bring sci-fi medical black technology to life again. Just earlier this month, "Cell" magazine published another major technical achievement of their team, through the high-frequency current emitted by two external electrodes, the "interference" generated at a specific position in the deep brain, to achieve non-invasive deep brain stimulation Effectively activate neuronal activity and even interfere with the behavioral response of mice!
The key is that the technology is completely non-invasive! And accurate! And effective! Not to mention cost and convenience!
In fact, in recent decades, physical stimulation of brain neurons to repair neurological dysfunction has attracted widespread interest from many scientists. Researchers have also been trying to use current to stimulate the brain, treat various diseases, restore and enhance body functions.
We know that the communication between neurons is actually an electrical signal, and the activity can be artificially excited or interrupted by external electrical pulses. The idea of ​​electrical stimulation therapy is to artificially intervene in the neural circuits of the brain to restore or improve the function or behavior of the body controlled by these specific neurons. However, it is not easy to do this.
The most advanced and accurate Deep Brain Stimulation therapy was established in 1987 to surgically implant electrodes in specific areas of the brain for therapeutic purposes. In 1997, the FDA approved the use of deep brain stimulation in patients with Parkinson's disease, and there is evidence that the technique can improve the symptoms of obsessive-compulsive disorder, and researchers have tried to treat other diseases such as depression and epilepsy. However, in the case of non-fatal diseases, craniotomy for the placement of electrodes is not a wise choice.
