ABSTRACT

On the last 15 years a new field of technological research has arisen in order to develop rehabilitation devices, they are called, brain computer interfaces. The main goal of these systems is to improve the quality of life of people with motor disabilities because of neuromuscular disorders like, amyotrophic lateral sclerosis, brain stroke and spinal cord injury. The brain computer interfaces systems provide these users with communication capabilities, for example, operate software to select letters in a computer or control neuroprostheses. These systems determine the user’s intentions to move or communicate, through the processing of electrical brain signals, typically, slow cortical potentials, visual evoked potentials, P300 potential, beta and mu rhythms, which are recorded on the scalp, and cortical neuronal activity, recorded by implanted electrodes in the brain. The recorded signals are translated into commands to operate in real-time a computer or another device. A successful operation requires that the user codes commands into brain signals and the brain computer interfaces system decodes the signals to identify these commands. This paper presents an introduction to brain computer interfaces research, characteristics, and the main applications to improve the quality life of people with motor disabilities.
