Electrical Geodesics, Inc. (EGI) is a specialized medical devices company that develops advanced electroencephalography apparatuses. Electroencephalography is the recording of electrical activity produced by the firing of neurons within the brain, and is used to study neurological disorders. The company has developed a dense-electroencephalography machine that has 128 to 256 channel leads, as compared to conventional systems with 8 to 19 channel leads. The higher quantity of leads enables for more detailed electrical activity recording, and this machinery has been used in breakthrough scientific works, including the works of recent US National Medal of Science recipients.
Electroencephalography is an invaluable diagnostic tool that enables the analysis of brain activity for identifying and studying the progression of neurological disorders. Electrical Geodesics Inc (EGI) has significantly advanced this technology by developing dense-electroencephalography that has approximately ten-times more recording units, or leads, than conventionally used apparatuses.
