TL;DR: Cardiac responses induced by motor imagery were investigated in 3 subjects in a series of experiments with a synchronous (cue-based) Brain-Computer Interface (BCI), which resulted in an acceleration of the heart rate in 2 subjects and a heart rate deceleration in the other subject.

TL;DR: Electroencephalogram (EEG) of hemiparetic stroke patients during left hand and right hand motor imagery is analyzed to determine whether time-frequency maps of Event-Related Desynchronization (ERD) and Event- Related Synchronization (ERS) and single-trial classification by means of the Distinctive Sensitive Learning Vector Quantification (DSLVQ) method are suited to keep record of the changing brain activity.

TL;DR: It was found for example that the component N90 varied in latency between 75 and 100 msec and was linked with the behaviour of the contralateral recorded potential amplitude of P150 and the amplitude of the averaged potential using all trials was about 30% too small.

TL;DR: It was found by DSLVQ that the most important electrode positions for differentiation between planning of left and right finger movement overlie cortical finger/hand areas over both hemispheres.

TL;DR: This chapter describes a method that allows the topographical display of brief (seconds) EEG changes using multiple EEG recordings that visualize event-related cortical activation patterns, similar to those obtained by the regional blood flow measurements with isotopes (landscapes) or by positron emission tomography.
