>Huber’s team specializes in optical techniques for stimulating and imaging brain activity instead of using invasive techniques that rely on electrodes. They regularly measure the activity of hundreds of neurons with single cell resolution by using a method called two-photon microscopy.
>Mario Prsa, a researcher at UNIGE and the first author of the study explained that they wanted to test whether mice would be able to learn to control a neural prosthesis by relying solely on artificial feedback from a sensory signal. To test this, they imaged neural activity in the motor cortex. When the mouse activated the specific neuron chosen for neuroprosthetic control, stimulation proportional to this activity was applied simultaneously to the sensory cortex by using blue light.
>Neurons of the sensory cortex were indeed rendered photosensitive to this light. This allowed the neurons to be activated by a series of optical flashes, which enabled the team to integrate them with the artificial sensory feedback signal. When the mouse achieved an above threshold activation, it was rewarded and 20 minutes later, once the association had been learned, the rodent was able to generate the correct neuronal activity more frequently.

>This meant that the sensation that had been created artificial was not only perceived, but also that it was integrated as a feedback of the prosthetic movement successfully. The brain machine interface functions bi-directionally in this manner. The Geneva researchers are of the opinion that the reason why this fictitious sensation is so rapidly assimilated, is that it most likely taps into very basic brain functions. Feeling the position of our limbs happens automatically without much thought being required. This probably indicates that fundamental neural circuit mechanisms are being used.
>This type of bidirectional interface might enable the development of robotic arms that are able to displace more precisely in the future. These would be able to feel touched objects, or perceive the required force to grasp them. The neuroscientists at UNIGE are also investigating how to produce sensory feedback that is more efficient. At the moment, they are only capable of doing so for a single movement, but are exploring the possibility to provide multiple feedback channels in parallel. This research lays the groundwork for developing a new generation of bidirectional neural prostheses that will be more precise

The bland acronym, BMI, obscures the true horror of this monstrosity. Its inventors promise a new era of genius, but meanwhile unscrupulous power brokers use its forcible installation to violate the sanctity of unwilling human minds. They are creating their own private army of demons.

Trump is physically, mentally, and realistically incapable of not only forming such a well stated sentence but speaking it out loud.
His head would explode as his eyes popped from their sockets were he to even read that.
Nice try, though.

"These machines, these "brain machine interface" things, are horrendous. Have you seen what they do to people? We've got to put a stop to it. They're trying to control your mind, and not even how fake news CNN is controlling your mind. I fought hard and won big league, against the meeedia, against the Republicans, against the fake liberal polls. We had a truly great landslide, because of you, the people!

Seems to complicated to be the real thing.
