It is reported that closed-loop reactive nerve stimulation system is an important application of "brain-computer interface" in clinical field. By implanting artificial intelligence chips into the skull and intracranial electrodes into the brain, the EEG rhythm is continuously monitored day and night. Once the upcoming epilepsy is predicted, it will start the exogenous interference rhythm and directly block the epilepsy formation in the epileptogenic focus.
Another Realization of Cyberpunk Technology
Friends who are interested in future technology should be familiar with the game Cyberpunk 2077. In the game, you can experience the fresh excitement brought by different "black technologies", such as robots, AR, VR, bionic people, memory transplantation technology, intelligent tracking weapons and so on. Bionic human technology, as one of the representative technologies, is similar to this brain-computer interface.
Bionic man is a combination of machine and man, who can gain better ability through machine and control the machine by "reading" the basic instructions of the brain.
Brain-computer interface requires us not only to read the information in the brain, but also to be able to "write", that is, in addition to being able to perceive information, we must also be able to respond. As a user interface, the user can read the information in the brain through the computer, and convert the signal into relevant feedback instructions after calculation and processing. Computers can accept commands from the brain or send signals to the brain.
As mentioned in the news, brain-computer interface can not only detect dangerous signals, but also interfere with and stop them, thus preventing dangerous behaviors. With the application of brain-computer interface technology in the medical field, more patients are about to get the hope of rebirth.
Development course of brain-computer interface technology
According to reports, the forms of brain-computer interface can be divided into non-invasive, semi-invasive and invasive according to the acquisition position in the brain. The biggest difference between the two is whether the brain operates with injury to obtain neuron information. Among them, the non-invasive mode only acts on the scalp; Semi-invasive device is implanted between scalp and cerebral cortex; Invasion is completely implanted in the cerebral cortex.
Brain-computer interface technology seems very sci-fi, in fact, as early as the 20th century, people have begun to study it.
In 1970s, the brain-computer interface oriented to motor function was first studied, which proved that monkeys could learn quickly and control the discharge frequency of individual neurons in the primary motor cortex freely under the action of closed-loop operating conditions. However, at this stage, the main research is animals. Until the 1990s, the brain-computer interface for sports developed rapidly, and people could capture neural signals in real time and control external devices through technology.
Thanks to many years of animal experiments, brain-computer interface technology has been gradually applied to human body. Early implantation equipment such as cochlear implant is helpful to restore impaired hearing, limb motor ability and vision.
What impressed me most was that at the opening ceremony of the 20 14 World Cup in Brazil, Juliano Pinto, a paraplegic youth, gradually recovered his lower limb motor function through brain-computer interface technology, and at the same time used artificial exoskeleton technology to drive the exoskeleton robot to walk, thus realizing the kick-off.
In China, Zhejiang University also completed the first clinical transformation research of implantable brain-computer interface in China in 2020. Patients can use cortical signals to accurately control external mechanical arms and manipulators to realize three-dimensional movement.
In recent years, with the continuous development of brain-computer interface technology, many enterprises began to lay out in the field of brain-computer interface.
Speaking of brain-computer interface, Neruallink, a neuroscience company invested by Musk, can be regarded as a representative enterprise in this field. Neuralink once implanted a chip on the brain surface of an experimental pig, and then wirelessly transmitted the brain movement of the pig to a computer for observation. They also implanted the same chip in the monkey's arm and hand, so that the monkey can control the cursor movement with his mind and catch the table tennis ball moving in the game.
In the research on the "invasive" brain-computer interface of human body, Neuralink Company of Musk provided a safer method to reduce the craniotomy to the size of a coin, thus reducing the trauma to the brain.
In addition to foreign science and technology companies, in recent years, a number of high-tech enterprises with brain-computer interface as their main business have emerged in China, such as Boruikang Neuracle Company, which was established at 20 1 1 to study the direction of innovative brain-computer interface. Kedou Brain Technology Co., Ltd., founded on 20 16, Ningju NeuraMatrix and Younao Yinhe, founded on 20 19, and Brain Tiger Neurox, founded on 202 1, etc. Using brain-computer interface, artificial intelligence and other technologies to provide technical support for medical treatment, entertainment, production and other fields.
final result
Looking at the development of brain-computer interface technology for decades, the research on brain-computer interface has brought convenience to people's lives, but there are also some concerns. After all, the chip implanted in the brain-computer interface will not have the same emotional changes as humans. When faced with the decision, it will only be implemented under the decision of the algorithm, and there will be no hesitation. And human beings are emotional, and the temporary dangerous consciousness behavior may be just thinking about it and not wanting to put it into action. If it is equipped with a brain-computer interface, it may directly perform this behavior, posing a threat to social security.
