A Stroke Study Reveals the Future of Human Growth


It starts with early in October 2017, when 108 stroke patients with significant arm and hand defects were screened for a separate clinical trial. The researchers will be operated on as a neurostimulator in their surgery vagus nerve, the cranial nerve that runs down the groove in the front of the neck and is responsible for transmitting signals from the brain to other parts of the body. By the time the trial was over, subjects who had previously had limited foot parts were already beginning to come to life. Either way, nerve pulses combined with rehab therapy give patients better use of their foot disabilities – and make it easier and more effective than any treatment before. it, even to those who have no answer.

This spring, the test findings were published on The Lancet. The change in paralysis, in itself, is a strange thing to do. But what is included in the article is something even more radical. not WHAT known to patients, however how they know this: By stimulating the vagus nerve, they withstand years of physical therapy for many months. The test was performed as a means of repairing the damage and restoring motor control. But what if there is no harm to begin with? In the hands of the healthy and fit, such technology could further improve physical performance-the question of whether people are ready to fight it.

The potential applications of this technology are not difficult to imagine. As seen in the test, when the vagus nerve receives more stimulation, it causes the brain to release neuromodulators, which control the body’s responses. They come online as the patient tests a new task, strengthening the involved motor circuits. “Whether you’re practicing golf or whatever, it’s the same,” explains Charles Liu, the study’s lead neurosurgeon and director of the USC Neurorestoration Center. “There’s not much difference between teaching a stroke victim to use a fork and teaching an elite athlete to hit a baseball.” It simply repeats the action and develops and strengthens the brain-motor circuits. If that process can be speeded up, then we just know how to optimize the brain-and how to add people. Today, biotech techniques such as stem cells show promise for repairing damaged nerves, while brain machine interfaces aim to replace lost function by bypassing damage and connecting. in the brain directly to the muscles. But this stroke study revealed that neuromodulation recovery plus the specific task being improved would improve. Learn Hebrew—Or relying on synaptic plasticity activity, with all your muscles firing in sequence. Often, to acquire a skill, the neurons in the brain must be burned in the right way at the right time; Practice is the usual human course, but now, awakening allows us to do it as quickly as possible, and even better.

It was only a matter of time before neuromodulation could be sold. Once it is modified and reached, there will probably be a lot of appeal for a public, and especially athletes, already interested in optimizing the human body. But in sports, competitions have regulations, and despite the usual controversies about doping, professional competitions are already on their fair share of anxiety and debate in this area. For example, the first trans woman to compete in the Olympics, Laurel Hubbard, is eligible to compete in the Tokyo Games if his total testosterone level (in serum) is below 10 nanomoles per liter and is at least 12 months old. But those are the same laws disqualifies two -time Olympic gold medalist Caster Semenya in South Africa because even though he has XY chromosomes, testosterone levels are also high.

Neurostimulation promises to make it even more complicated. Unlike steroids or hormones, there is no clear way to monitor it. In a healthy person with full use of their limbs, it may be impossible to track whether vagus nerve stimulation has occurred or not or at any time. If the athlete has an implanted neurotransmitter, that may be suggested, but not convinced. After all, the body releases its own neuromodulators; nothing separate from the self is stimulated by electricity foreign to the body. Even if the Olympic committee notifies regulatory requirements such as those of testosterone levels, the measurement of brain stimulation requires that athletes or promoters provide use of the document, or some form of internal implant device tests. . Although it is necessary to guard the brain of an athlete to break one of the last vestiges of private space; any form of regulation must be accompanied by instructions to protect against abuse. These monitoring and enforcement mechanisms need to be addressed-and quickly, before technology overtakes our behavior.
