|A direct communication pathway between the brain's electrical activity and an external device|
A brain–computer interface (BCI), sometimes called a brain–machine interface, is a direct communication pathway between the brain's electrical activity and an external device, most commonly a computer or robotic limb. BCIs are often directed at researching, mapping, assisting, augmenting, or repairing human cognitive or sensory-motor functions. Implementations of BCIs range from non-invasive (EEG, MEG, EOG, MRI) and partially invasive (ECoG and endovascular) to invasive (microelectrode array), based on how close electrodes get to brain tissue.
Neural lace is an ultra-thin mesh that can be implanted in the skull, forming a collection of electrodes capable of monitoring brain function. It creates an interface between the brain and the machine.
With one way to insert such a neural lace, a tiny needle containing the rolled up mesh is placed inside the skull and the mesh is injected. As the mesh leaves the needle it unravels, spanning the brain. Gradually, the lace will be accepted as part of the brain, and will even move with it as it grows or very slightly changes size.
|Ray Kurzweil||“Our thinking then will be a hybrid of biological and non-biological thinking. We’ll be able to extend our limitations and think in the cloud. We’re going to put gateways to the cloud in our brains...We’re going to gradually merge and enhance ourselves. In my view, that’s the nature of being human – we transcend our limitations.”||Ray Kurzweil||2015|
