Development of an MEG-based brain–computer interface
TLDR
The results showed that a classifier based on multi-task learning with a l2,1-norm regularized logistic regression was the best method for across-subject decoding for both MEG and EEG, and the methods presented are suitable for a real-time MEG-based BCI.
The use of MEG-based brain computer interface for classification of wrist movements in four different directions
TLDR
This study will validate signal processing and classification methods for Brain-Computer Interfaces to classify the direction of wrist movements using brain activity that was recorded with MEG from two healthy, right-handed subjects.
A High Performance MEG Based BCI Using Single Trial Detection of Human Movement Intention
TLDR
If the spatial resolution of the signal is high enough, discrimination of different movement intentions from the spatiotemporal distribution of oscillatory brain activity should be possible on a single trial basis and could be harnessed as a flexible control signal for external devices in the design of brain computer interfaces (BCI).
Modulation of MEG signals during overt and imagined wrist movement for brain-computer interfaces
TLDR
Frequency-domain analysis of the MEG signals reveals consistent modulation during both overt and imagined movements on sensors overlaying sensorimotor areas of the brain, suggesting that MEG may be an important tool for the development of BCIs, and for the identification of regions for future insertion of electrodes for neuroprosthetic control.
Gamma band activity associated with BCI performance: simultaneous MEG/EEG study
TLDR
Results showed that gamma activity had a high positive correlation with MI performance in the prefrontal area, and this trend was also found across sessions within one subject, indicating a critical role in BCI performance.
A Comparative Study on the Detection of Covert Attention in Event-Related EEG and MEG Signals to Control a BCI
TLDR
It is shown that BCI control by covert attention is feasible with EEG and MEG using a data-driven spatial filter approach with a clear advantage of the MEG regarding DA but with a better transfer learning in EEG.
A Multifaceted Approach to Covert Attention Brain-Computer Interfaces
TLDR
Three different approaches were explored that could lead to better performing and more inclusive CVSA BCI systems and helped to further understand CVSA and lay out a useful basis for further exploration of the connection between behavior and alpha power oscillations in CVSA tasks.
Brain Computer Interfaces, a Review
TLDR
The state-of-the-art of BCIs are reviewed, looking at the different steps that form a standard BCI: signal acquisition, preprocessing or signal enhancement, feature extraction, classification and the control interface.
Sources of Electrical Brain Activity Most Relevant to Performance of Brain-Computer Interface Based on Motor Imagery
TLDR
The analysis of BCI performance based on motor imagination is the object of the present chapter.

TLDR
It is shown that a noninvasive BCI that uses scalp-recorded electroencephalographic activity and an adaptive algorithm can provide humans, including people with spinal cord injuries, with multidimensional point-to-point movement control that falls within the range of that reported with invasive methods in monkeys.
Brain-computer interface (BCI) operation: signal and noise during early training sessions
On the suitability of near-infrared (NIR) systems for next-generation brain-computer interfaces.
TLDR
This paper has used practical non-invasive optical techniques to detect characteristic haemodynamic responses due to motor imagery and consequently created an accessible BCI that is simple to attach and requires little user training.
Classifying Event-Related Desynchronization in EEG, ECoG and MEG Signals
TLDR
This work employed three different brain signal recording methods to perform Brain-Computer Interface studies on untrained subjects, finding that spatial filtering does not help in MEG, helps a little in ECoG, and improves performance a great deal in EEG.
BCI2000: a general-purpose brain-computer interface (BCI) system
TLDR
This report is intended to describe to investigators, biomedical engineers, and computer scientists the concepts that the BCI2000 system is based upon and gives examples of successful BCI implementations using this system.
Magnetoencephalographic signals predict movement trajectory in space
TLDR
An excellent prediction of movement trajectory by real-time magnetoencephalography (MEG) is demonstrated and this congruence was robust since it remained high in cross-validation analyses.
How many people are able to operate an EEG-based brain-computer interface (BCI)?
TLDR
Ninety-nine healthy people participated in a brain-computer interface (BCI) field study conducted at an exposition held in Graz, Austria, and nearly 93% of the subjects were able to achieve classification accuracy above 60% after two sessions of training.
Magnetoencephalography-theory, instrumentation, and applications to noninvasive studies of the working human brain
TLDR
The mathematical theory of the method is explained in detail, followed by a thorough description of MEG instrumentation, data analysis, and practical construction of multi-SQUID devices.
