The base of operations for the brains of a computer is the motherboard. The motherboard serves as a literal base for many of the other elements inside your computer. It's a great printed circuit board. The motherboard provides connections and sockets that allow other components to communicate with each other. Motherboards come in different shapes and sizes - a motherboard on a laptop computer might not look like one on a desktop PC.
The brain of the computer is a microprocessor called the central processing unit (CPU). The CPU is a chip that contains millions of tiny transistors. It is the job of the CPU to perform the calculations necessary to make the computer work - the CPU transistors manipulate the data. You can think of a CPU as the decision maker.
A brain computer interface (BCI), sometimes called a mind-machine interface (MMI), direct neural interface (DNI) or brain-machine interface (BMI), is a direct communication path between an improved brain or wiring and a device external. BCIs are often directed at research, mapping, assisting, increasing, or repairing human or sensory-motor cognitive functions.
Research on BCIs began in the 1970s at the University of California, Los Angeles (UCLA) under a grant from the National Science Foundation, followed by a contract from DARPA. Documents published after this research also mark the first emergence of the expression brain-computer interface in the scientific literature.
The field of BCI research and development has since focused mainly on neuro-protection applications that aim to restore damaged hearing, vision and movement. Thanks to the remarkable cortical plasticity of the brain, signals from implanted prostheses can, after adaptation, be handled by the brain as the natural sensor or effector channels. After years of experimentation with animals, the first neuro-protetic devices implanted in humans appeared in the mid-1990s.
