![]() ![]() Data classification is then performed via a linear discriminant analysis. This sequence involves displaying and training a person on specific visual stimuli, recording an EEG, and analyzing the EEG using artifact control and feature extraction by filtering common spatial patterns. BSanalyze software from g.tec to implement a BCI. A sequence of processing steps can be performed with g. ![]() They have used distinct EEG patterns acquired during feedback experiments to develop a brain-computer-interface (BCI). G.tec, a MathWorks Connections Partner based in Graz, Austria, develops hardware and software for biosignal processing. ![]() During the last seven decades, electroencephalography, or EEG, has been established as a tool for monitoring brain dynamics and brain function. In 1929, Hans Berger performed the first noninvasive measurements of bioelectrical activity in the brain. This article describes how products from g.tec, which were built on MATLAB ® and Simulink ®, can be used to perform this multimodal acquisition and analysis. Advances in the acquisition and analysis of biosignals such as electroencephalograms (EEGs) and electrocorticograms (ECoGs) are profoundly improving brain wave research, creating opportunities to bypass severed nerve pathways to control prostheses and allow movement of paralyzed body parts. ![]()
