TL;DR
Digital signal processing technology provides the speed and flexibility needed to satisfy the requirements of real-time EEG analysis in real time, and supports evaluation of alternative analysis and control algorithms, and thereby facilitates further BCI development.
Abstract
We are developing an electroencephalographic (EEG)-based brain-computer interface (BCI) system that could provide an alternative communication channel for those who are totally paralyzed or have other severe motor impairments. The essential features of this system are as follows: (1) EEG analysis in real time, (2) real-time conversion of that analysis into device control, and (3) appropriate adaptation to the EEG of each user. Digital signal processing technology provides the speed and flexibility needed to satisfy these requirements. It also supports evaluation of alternative analysis and control algorithms, and thereby facilitates further BCI development.

The analyses suggest that this communication channel can be operated accurately at the rate of 0.20 bits/sec, which means that subjects can communicate 12.0 bits, or 2.3 characters, per min.

347 Citations1978William N. Kuhlman
Topographic and functional testing was conducted to determine if the Rolandic mu rhythm could be reliably detected from the human scalp, and to describe its spatiotemporal and functional characteristics in relation to the feline sensorimotor rhythm (SMR).

It is concluded that both the presence and blocking of mu rhythm are specific to the somatic representation of the cortex from which it is recorded and its functional significance may be similar to other sensory rhythms like the occipital alpha rhythm.
