Common Misconceptions

Stentrode vs Neuralink

When it comes to brain-computer interfaces, two of the most talked-about technologies are the Stentrode and Neuralink. However, there are some common misconceptions that people have about these devices:

  • Stentrode misconceptions:
  • 1. The Stentrode is a painful surgical procedure: Contrary to popular belief, the Stentrode is a minimally invasive procedure that does not require open brain surgery. It is a tiny device that is inserted via a blood vessel into the brain, making the procedure less painful and risky compared to traditional brain implants.
  • 2. The Stentrode can read people’s thoughts: While the Stentrode is capable of recording neural signals from the brain, it cannot read thoughts. It can only detect specific patterns in brain activity related to movement, enabling users to control external devices such as a wheelchair or a computer cursor.
  • 3. The Stentrode is only for people with severe disabilities: Another misconception is that the Stentrode is only designed for individuals with severe paralysis. While it has shown promising results in assisting those with paralysis, the technology also has the potential to be used in a wider range of applications such as augmenting human capabilities in various fields.
  • Neuralink misconceptions:
  • 1. Neuralink can turn humans into cyborgs: One common misconception is that Neuralink can turn humans into cyborgs by enhancing their cognitive abilities beyond natural limits. However, the current capabilities of Neuralink are limited to working with brains to address medical conditions and disabilities, not enhancing normal human capabilities.
  • 2. Neuralink allows for mind control: Some people mistakenly believe that Neuralink can control a person’s mind through invasive brain implants. However, Neuralink is focused on providing a means for individuals to control external devices through their thoughts, rather than allowing external entities to control their minds.
  • 3. Neuralink is ready for widespread implantation: While Neuralink has shown promising results in animal trials, it is still in the early stages of development and is not yet ready for widespread implantation in humans. The technology requires further testing and refinement before it can be considered safe and effective for general use.
