TLDR
Heart rate responses induced by motor imagery were investigated in 4 subjects in a series of experiments with a Brain-Computer Interface (BCI) and thought-based control of VE resulted in a heart rate increase in 2 subjects and aheart rate decrease in the other 2 subjects.Abstract:
Heart rate responses induced by motor imagery were investigated in 4 subjects in a series of experiments with a Brain-Computer Interface (BCI). The goal of the BCI experiment was either to control a bar on a PC monitor or to move forward within a virtual environment (VE). In the first case all subjects displayed a HR decrease during motor imagery in the order of 2 – 5 %. The thought-based control of VE resulted in a heart rate increase in 2 subjects and a heart rate decrease in the other 2 subjects. The heart rate acceleration in the VE is interpreted as effect of mental effort and motivation.read more

Surround-screen projection-based virtual reality: the design and implementation of the CAVE
TL;DR: This paper demonstrates that projection technology applied to virtual-reality goals achieves a system that matches the quality of workstation screens in terms of resolution, color, and flicker-free stereo, and demonstrates that this format helps reduce the effect of common tracking and system latency errors.

TL;DR: The results of cortical activity support the hypothesis that motor imagery and motor performance possess similar neural substrates as well as the assumption that the posterior cerebellum is involved in the inhibition of movement execution during imagination.

TL;DR: The hypothesis that MI and MP involve overlapping neural networks in perirolandic cortical areas is supported by functional magnetic resonance imaging techniques.

Differential modulation of corticospinal excitability during observation, mental imagery and imitation of hand actions
TL;DR: The similarity found between observation and imagery of hand actions in terms of corticospinal facilitation is interpreted in the light of the motor-simulation theory of Jeannerod, which proposes that perceiving actions involves neural simulation of the same action by the observer, thereby explaining the parallel between actions observed and actions imaged at the representational level.
14 Human Brain-Computer Interface
TL;DR: A brain‐computer interface (BCI) transforms signals originating from the human brain into commands that can control devices or applications, which can be used to assist patients who have highly compromised motor functions, as is the case with patients with severe motor disabilities.
