Recently, the use of electronic chips to control the movement of mice has caused a lot of media attention. This technology may greatly help the patients to regain their walking ability.
In the middle of the test, the spinal cord in the back of the mouse has been cut off, and the brain signal does not reach the lower spinal cord, but it can transmit current to the spinal nerve through the neurosurgical implant, enabling them to walk on the treadmill. Scientists can control the movement of mice by changing electrical signals. In the experiment, the mouse successfully took a thousand steps and challenged the stairs of various heights and lengths.
Professor Gregoire CourTIne of the Federal Institute of Technology in Lausanne, Switzerland, is the lead researcher of the study. He said: "We have completely controlled the hind legs of the mice. It has no control over its limbs, but we can reactivate the severed spinal cord. And stimulate to let the mouse walk naturally. We can control the way the mouse walks forward and the height of the leg."
The study is part of the European “neurological walking†project, which is scheduled to be tested on human patients as early as next summer. Scientists have designed a humanized device for clinical trials. Dr. Silvestro Micera, also from the Federal Institute of Technology in Lausanne, Switzerland, said, “We can use these simple neurological findings to develop more effective neuroprosthetic techniques. We believe that this technology will greatly improve those encountering neurological disorders sooner or later. The quality of life of the group."
Dr. Jarrod Bailey, from the UK's “Abolition of Living Anatomy†organization, condemned the study. He pointed out: “The mice in the experiment will suffer unimaginable pain, the public will not support this research, and the animal spine will be cut off. Animal mites simply cannot mimic the long-term effects of spinal cord injury on humans."
Description of Automotive Split Braided Sleeve Loom For Cable And Wire Wrap
1. Braided Wrap Around Sleeving offers innovative solutions for the protection of breakout areas
and provides easy removal when is necessary an inspection or maintenance of cables.
2. The special open structure allows to be installed after other components, for example copper terminals and connectors.
PET Wrap provides the same flexibility and abrasion resistance as the PET Expandable Braided Sleeving but with the added feature of a hook and loop closure running the length of the material.
This allows you to work on segments of the cabling, rather than having to remove the entire covering and re-run all of its contents.
