Electrical Geodesics, Inc. in Summary

Founded in 1992, EGI designs, develops and commercialises a range of non-invasive neurodiagnostic and neuromodulation products used to monitor, interpret and modulate brain activity, based on its proprietary dense array electroencephalography ("dEEG") platform technology. The Company's technology uses up to 256 sensors, providing much higher resolution brain activity data compared to conventional 8 or 16 channel EEG and is used in medical, clinical and research settings in a diverse range of applications including important areas such as the diagnosis and monitoring of epilepsy, neurosurgical planning, sleep assessment, and many others.

EGI's dEEG systems, available in the GES 300 and now the GES 400 lines, capitalise on the Company's unique Hydrocel Geodesic Sensor Net which allows faster, easier, and more convenient placement of many EEG sensors in an even distribution over the entire scalp, providing more accurate and precise diagnosis and measurement. EGI's technology is now widely used in neuroscience research laboratories and is becoming more commonly used in clinics, care centers, and hospitals around the world. Data is measured and visualised using EGI's proprietary amplifier technology and software, providing a complete, advanced, high-resolution EEG platform. The Company's products are compatible with multiple diagnostic and imaging technologies, including magnetic resonance (MR) imaging, functional MRI (fMRI), and magneto-encephalography (MEG).
