TLDR
Perelmouter et al. as mentioned in this paper have been teaching severely or totally paralyzed patients to successfully control the movements of a cursor on a computer screen by means of systematic changes in the amplitudes of their slow cortical potentials.Abstract:
Since 1996 we have been teaching more than 18 severely or totally paralyzed patients to successfully control the movements of a cursor on a computer screen by means of systematic changes in the amplitudes of their slow cortical potentials (SCPs; Birbaumer, Ghanayim, Hinterberger, Iversen, Kotchoubey et al., 1999). Patients learned regulation of their SCP amplitudes by means of a brain-computer interface (BCI) and on-line feedback about the time course of SCP amplitude shifts, represented by cursor movements on a computer screen. When patients were able to successfully regulate their SCP amplitude, they were trained to use this ability to communicate with friends and caregivers by means of a Language Support Program (Perelmouter, Kotchoubey, Kubler, Taub, & Birbaumer, 1999). Having a reliable predictor of progress in training would be particularly helpful because training patients at their homes requires substantial effort and a positive outcome is desirable given limited personal and financial re...read more

Neurophysiological Predictor of SMR-based BCI Performance
Benjamin Blankertz,Claudia Sannelli,Sebastian Halder,Eva Maria Hammer,Andrea Kübler,Andrea Kübler,Klaus-Robert Müller,Gabriel Curio,Thorsten Dickhaus +8 more
TL;DR: A neurophysiological predictor of BCI performance is proposed which can be determined from a two minute recording of a 'relax with eyes open' condition using two Laplacian EEG channels.

Towards a Cure for BCI Illiteracy
TL;DR: A sophisticated adaptation scheme is presented which guides the user from an initial subject-independent classifier that operates on simple features to a subject-optimized state-of-the-art classifier within one session while the user interacts the whole time with the same feedback application.

Brain-computer interfaces and communication in paralysis: extinction of goal directed thinking in completely paralysed patients?
TL;DR: A strong correlation has been found between physical impairment and BCI performance, indicating that performance worsens as impairment increases, and whether locked-in patients can transfer learned brain control to the CLIS remains an open empirical question.

TL;DR: It is concluded that with sufficient training time an auditory BCI may be as efficient as a visual BCI and Mood and motivation play a role in learning to use a BCI.

The influence of psychological state and motivation on brain-computer interface performance in patients with amyotrophic lateral sclerosis - a longitudinal study
TL;DR: Motivational factors may be related to BCI performance in individual subjects and motivational factors and well-being should be assessed in standard BCI protocols, which recommends using P300-based BCI as first choice in severely paralyzed patients who present with a P300 evoked potential.

The ten-twenty electrode system of the international federation
TL;DR: During the First International EEG Congress, London in 1947, it was recommended that Dr. Herbert H. Jasper study methods to standardize the placement of electrodes used in EEG (Jasper 1958).
Mechanisms of Skill Acquisition and the Law of Practice
TL;DR: In this article, both experimental and theoretical approaches are employed in an investigation of the mechanisms underlying the performance improvement that occurs in practice, and it is argued that a single law, the power of law of practice, adequately describes all of the practice data.

TL;DR: A new means of communication for the completely paralysed that uses slow cortical potentials of the electro-encephalogram to drive an electronic spelling device is developed.
