The document discusses brain-computer interface (BCI) technology, also known as brain chip technology. It begins with an introduction and overview of BCI, including block diagrams showing the translation of brain signals into device commands. The document then covers different types of BCI, such as invasive and non-invasive methods, as well as various BCI projects including BrainGate and using thought to control devices like robots and games. Potential advantages of BCI are discussed, such as helping paralyzed patients control prosthetics, as well as disadvantages like the crudeness of current technology and issues with electrodes. In conclusion, BCI technology allows communication based on neural activity and provides paralyzed individuals new ways to interact with their environments through a direct

matter of the brain during neurosurgery.
 Invasive devices produce the highest quality
signals of BCI devices but are prone to scar- tissue
build-up.

15.  Research is still in beginning stages
 The current technology is crude
 Electrodes outside of the skull can detect very few electric
signals from the brain
 Electrodes placed inside the skull create scar tissue in the
brain

16.  Brain Chip Technology is a technology which
involves communication based on neural activity
generated by the brain.
 It gives paralyzed patients greater ability to interact
with their environments.
 The Brain Gate Neural Interface creates a direct link
between a person's brain and a computer, translating
neural activity into action.
