Abstract :
Planning and preparing voluntary finger movements result in a specific topographical pattern of event-related desynchronization (ERD) in the alpha band. These patterns generated for planning left and right hand movements show large enough differences to be seperable by a Learning Vector Quantizer (LVQ). This paper describes one-dimensional control of a cursor on a computer monitor based on the differentiation of two cortical activation patterns measured by two EEG channels.
