Mind-controlled prosthetic allows movement of individual fingers

With some important advances in neuroscience and robotics over the past few years, the use of mind control prosthesis is a bold idea that is becoming realistic. Well, the research team is advocating another major advance in this field, building prostheses with individual fingers that can be controlled by the heart to the little finger

I saw some psychically controlled prostheses designed to allow limb amputees to perform more complex tasks better. These include a bionic hand for gripping an object, which also includes a system that allows two prostheses to be controlled at the same time, allowing the patient to feel tactile.

Presently, researchers at Johns Hopkins University have built a prosthesis that claims to provide it before something is offered. It is the ability to control your fingers independently from each other with your mind. As the team does not miss his arm but has epilepsy, I will work with male subjects who began brain mapping to determine the origin of his seizure

A neurosurgeon implanted 128 electrode arrays on a part of the brain that controls the movement of the hands and arms. Researchers then instructed the subject to move one finger while using a special computer program to monitor which part of the brain was emitting electrical signals.

Then the team focused on measuring brain activity related to tactile sense by wearing gloves with a small vibrator on the fingers. Then they sing and record the electrical signals from the brain using their fingers.

With this dynamic sensory data, the team illuminates the prosthesis to move the fingers based on what part of the brain is illuminated. They connected the prosthesis to the electrodes of the patient's brain and instructed him to consider moving each finger, and found that the electrical signal was sufficient to cause the corresponding prosthetic finger movement.

Initially the body could be controlled by thinking with accuracy of 76%, but researchers could increase it to 88% by grouping the ring and little finger together. They say that the brain controlling two fingers partially overlap, people usually move them together, so the expected accuracy increases.

Although the proof-of-concept system is a promising development that has the promise of restoring finer hand functions for limb amputees, researchers took years and years to apply this technology in the real world I point out. It includes many brain maps and computer programming.

You can see a demonstration of the movement of the mind-controlled fingers in the video below. This research was published in the journal Neuroengineering.

As a doctoral student, I have the opportunity to work at the neural prosthetic laboratory. My thesis is to decode individual finger movements from forearm and brain wireless electromyogram (EMG) records. The idea is that these signals can theoretically be used to control the dexterity of the finger if these devices can prove that the necessary finger movements can be predicted based on the physiological signals of the residual muscle in the forearm and brain It is possible to be extracted from human limb amputee. Prosthesis The final application is basically the prosthetic foot of Luke Skywalker in Empire Strike's Back.

With some important advances in neuroscience and robotics over the past few years, the use of mind control prosthesis is a bold idea that is becoming realistic. Well, the research team is advocating another major advance in this field. And we are building a prosthesis that allows individual fingers to be controlled by mind until the little finger. Currently, researchers at Johns Hopkins University have built up a prosthesis that claims to provide something before it becomes available, that is, the ability to control the fingers independently of one another using the mind.
