Revolution or Risk? Neuralink's Controversial Path

Neurolink brain implant is pushing the boundaries of what is considered safe or even possible when it comes to brain computer interface technology.

Neurolink is in a vulnerable position right now as they begin to face the realities of human experimentation.

A ghost from Elon Musk's past has returned to take the throne with a better, safer brain implant.

Neurolink has been testing a new ultra thin film array that's only one fifth the thickness of a human hair and covered with 1024 tiny electrode sensors.

It's designed to sit on top of your brain, where it can eavesdrop on all of the conversations that your neurons are having without ever causing any physical damage to your brain matter.

The new plan is to place the threads 8mm deep into Neuralink 's second human patient.

This is still not nearly as deep as other current electrode procedures, like deep brain stimulation for example.

Precision has already tested its layer 7 cortical interface with 14 human patients over the past three years .

This is made possible because the thin film array is so easy and harmless to place onto and remove from the brain that the procedure can be incorporated into any routine neurosurgery.

Right now, Neurolink is only going ahead with their implant in people who already have full body paralysis, so that limits their research to imagined movement.
