One of these, the micro-electrocorticography (ECoG) electrode grid, is placed beneath the skull and on the surface of the brain's movement-controlling motor cortex. A computer system interprets the electrical impulses in the brain captured by the micro-ECoG technology and then converts the signals into movement controls in virtual environments.

Say you did this to a person who is not paralyzed… can still control the motor cortex…. a computer interface…. why just the motor cortex…

what about all the other brain cortices that can be controlled?

Implanted intracortical electrodes as chronic neural interfaces to the

central nervous system

Abstract

Recent developments in neural interfaces show that it is possible to have fine control of a robotic

prosthetic by interfacing with the motor cortex of the human brain. Development of long term systems for this purpose is a challenging task with many different possibilities. Intracortical implants

have shown the most promise in providing enough signal selectivity and throughput for complex

control systems with many degrees of freedom. Intracortical systems generally fall into two categories: MEMS devices and bundle of wire systems. While both show promise, MEMS systems

have been greatly popularized due to their reproducibility. In particular, the Michigan probe and

Utah microarray are often used as a base for construction of more complex intracortical systems.

However, these systems still carry many downsides. Their long-term viability is questionable, with

mixed results. The effects of damage from implantation are still inconclusive and immune responses

remain a problem for long-term use. While there is some promising research in the use of bioactive molecules and biocompatible materials to prevent immune responses, more controlled study is

needed before intracortical systems become widespread.
