“…They used a gamification approach-in the 2D paradigm, the game "Bugz Shooter" was used, where participants had to shoot bugs with water bubbles depending on frontal alpha asymmetry. For the 3D group, a car driving game was presented, and the car would drive depending on the alpha asymmetry (Hafeez et al, 2019). As the studies did not include control groups one cannot differ between NF-specific effects and unspecific 3D/VR-related effects.…”

Electroencephalography-neurofeedback (EEG-NF) has become a valuable tool in the field of psychology, e.g., to improve cognitive function. Nevertheless, a large percentage of NF users seem to be unable to control their own brain activation. Therefore, the aim of this study was to examine whether a different kind of visual feedback could positively influence NF performance after one training session. Virtual reality (VR) seems to have beneficial training effects and has already been reported to increase motivational training aspects. In the present study, we tested 61 young healthy adults (mean age: 23.48 years; 28 female) to investigate, whether 3D VR-based NF training has a more beneficial effect on the sensorimotor rhythm (SMR, 12–15 Hz) power increase than a mere 2D conventional NF paradigm. In the 3D group, participants had to roll a ball along a predefined path in an immersive virtual environment, whereas the 2D group had to increase the height of a bar. Both paradigms were presented using VR goggles. Participants completed one baseline and six feedback runs with 3 min each, in which they should try to increase SMR power over Cz. Half of the participants received real feedback whereas the other half received sham feedback. Participants receiving 3D VR-based feedback showed a linear increase in SMR power over the feedback runs within one training session. This was the case for the real as well as for the sham 3D feedback group and might be related to more general VR-related effects. The 2D group receiving the conventional bar feedback showed no changes in SMR power over the feedback runs. The present study underlines that the visual feedback modality has differential effects on the NF training performance and that 3D VR-based feedback has advantages over conventional 2D feedback.

“…Beta frequency band reflects brain activities with faster oscillation, and has been associated with concentration [ 64 ], alertness [ 65 ], and attention [ 66 , 67 , 68 ]. Changes in the beta activity over the sensorimotor cortex has been associated with sensorimotor control and peripheral muscular activity [ 69 ].…”

“…In our study, the increase of beta activity during the VR trials is dominantly due to the increase of high-beta sub-band (18–30 Hz). This sub-band has been associated with higher level of concentration but with increasing emotional intensity such as anxiety [ 52 ] and agitation [ 68 ]. Errico et al used the ratio of high-beta to low-beta sub-bands to calculate alertness index [ 22 ] in a study on emotion reactions within the VR.…”

Adults are constantly exposed to stressful conditions at their workplace, and this can lead to decreased job performance followed by detrimental clinical health problems. Advancement of sensor technologies has allowed the electroencephalography (EEG) devices to be portable and used in real-time to monitor mental health. However, real-time monitoring is not often practical in workplace environments with complex operations such as kindergarten, firefighting and offshore facilities. Integrating the EEG with virtual reality (VR) that emulates workplace conditions can be a tool to assess and monitor mental health of adults within their working environment. This paper evaluates the mental states induced when performing a stressful task in a VR-based offshore environment. The theta, alpha and beta frequency bands are analysed to assess changes in mental states due to physical discomfort, stress and concentration. During the VR trials, mental states of discomfort and disorientation are observed with the drop of theta activity, whilst the stress induced from the conditional tasks is reflected in the changes of low-alpha and high-beta activities. The deflection of frontal alpha asymmetry from negative to positive direction reflects the learning effects from emotion-focus to problem-solving strategies adopted to accomplish the VR task. This study highlights the need for an integrated VR-EEG system in workplace settings as a tool to monitor and assess mental health of working adults.

“…During the study [8], a number of parameters were investigated for the performance enhancements. These parameters included the threshold selection, effect of environment colors [25], game platform [19] and instructions from the practitioners. The observations and the analysis in [8], are critical to identify the enhancements in development of the GSC.…”

“…The selection of stimulus contents is based on the practitioner's expertise for a particular therapeutic application of neurofeedback training. Several studies have used different stimulus contents for neurofeedback training for different applications related to cognitive therapeutic effects (e.g., audio stimulus content [14]- [16], audio-visual stimulus content [17], [18], and game stimulus content (GSC) [5], [7], [8], [19]).…”

The neurofeedback stimulus content has direct implications for the efficacy of the psychophysiological applications for neurofeedback modality. In particular, enhancements of neurofeedback stimulus content can facilitate improvements in the efficacy of neurofeedback applications in clinical practice. To further elaborate on this aspect, this study introduced systematic enhancements in neurofeedback stimulus content by developing enhanced neurofeedback stimulus content for stress mitigation. The enhancements included the automatic selection of color of neurofeebdack stimulus content environment and instruction messages, as well as, the adaptive selection of threshold of quantitative electroencephalogram (QEEG) features, such as frontal alpha power and frontal alpha asymmetry. The enhancements were based on the outcomes from previous research on the selection of neurofeedback stimulus content for stress mitigation. The improvement in the efficacy of neurofeedback stimulus content was measured statistically by comparing the QEEG and topographic maps. In this study, electroencephalogram data from 20 participants were acquired during multiple sessions of neurofeedback. Analysis of variance and a post hoc test were used to verify the improvement in the efficacy of the neurofeedback application for stress mitigation after the enhancements of the neurofeedback stimulus content; a t-test was used to verify the statistical significance of the stress mitigation by the neurofeedback p < 0.05. The results indicate that the enhancement of the developed neurofeedback stimulus content facilitated stress mitigation during the early sessions of neurofeedback. In conclusion, the efficacy of neurofeedback can be improved using the developed stimulus content with enhancements.
