“… 45 As for mental rotation, previous work used visually presented cues that had to be mentally rotated, such as geometric objects. 46 – 57 We did not visually present the target object, as participants had to imagine a person rotating while keeping their eyes closed. In turn, unlike the reported studies, there was no reference object to compare to the rotated item.…”

Guiding functional near-infrared spectroscopy optode-layout design using individual (f)MRI data: effects on signal strength

et al. 2021

. Significance: Designing optode layouts is an essential step for functional near-infrared spectroscopy (fNIRS) experiments as the quality of the measured signal and the sensitivity to cortical regions-of-interest depend on how optodes are arranged on the scalp. This becomes particularly relevant for fNIRS-based brain–computer interfaces (BCIs), where developing robust systems with few optodes is crucial for clinical applications. Aim: Available resources often dictate the approach researchers use for optode-layout design. We investigated whether guiding optode layout design using different amounts of subject-specific magnetic resonance imaging (MRI) data affects the fNIRS signal quality and sensitivity to brain activation when healthy participants perform mental-imagery tasks typically used in fNIRS-BCI experiments. Approach: We compared four approaches that incrementally incorporated subject-specific MRI information while participants performed mental-calculation, mental-rotation, and inner-speech tasks. The literature-based approach (LIT) used a literature review to guide the optode layout design. The probabilistic approach (PROB) employed individual anatomical data and probabilistic maps of functional MRI (fMRI)-activation from an independent dataset. The individual fMRI (iFMRI) approach used individual anatomical and fMRI data, and the fourth approach used individual anatomical, functional, and vascular information of the same subject (fVASC). Results: The four approaches resulted in different optode layouts and the more informed approaches outperformed the minimally informed approach (LIT) in terms of signal quality and sensitivity. Further, PROB, iFMRI, and fVASC approaches resulted in a similar outcome. Conclusions: We conclude that additional individual MRI data lead to a better outcome, but that not all the modalities tested here are required to achieve a robust setup. Finally, we give preliminary advice to efficiently using resources for developing robust optode layouts for BCI and neurofeedback applications.

“…Motor imagery is considered effective for learning and practicing movements in many fields. [ 25 ] Mental practice of action using motor imagery is performed in post-stroke rehabilitation and sports science. This technique is forms part of psychological skills training that supports physical or rehabilitative practice, the goal normally being to enhance or maintain performance of a skill or task.…”

Background: We aimed to examine the feasibility of our newly-developed, integrated, and high-intensity individual cognitive behavioral therapy (CBT) protocol for treatment-resistant chronic pain. Methods: We conducted an open-labeled prospective single-arm trial for patients aged 18 years and above, suffering from chronic pain, and diagnosed with somatic symptom disorder with predominant pain. We provided 16 weekly sessions of CBT, each lasting for 50 minutes, which included 4 new strategies: attention shift, memory work, mental practice, and video feedback. For comparison, the study had a pre-test post-test design. The primary outcome was the change from baseline (week 1) to 16, as indicated by the Numerical Rating Scale and Pain Catastrophizing Scale. In addition, we evaluated depression, anxiety, disability, and quality of life as secondary outcomes. Results: Sixteen patients with chronic pain underwent our CBT program. Though there was no reduction in pain intensity, catastrophic cognition showed statistically significant improvement with a large effect size. Depression, anxiety, and disability demonstrated statistically significant improvements, with small to moderate effect sizes. No adverse events were reported. Conclusion: Our newly integrated CBT program for chronic pain may improve catastrophic cognition, depression, anxiety, and disability. Large-scale randomized controlled studies are necessary to investigate the program's effectiveness in the future.

“…Here, we asked participants to recite common multiplication tables, which is considered an easy task and thus may have elicited lower responses in frontal and parietal areas when compared to more complex multiplication problems 73 . Regarding mental rotation, most of the reviewed work used visually presented cues that had to be mentally rotated, such as geometric object, alphanumeric character or hand rotations 61,[74][75][76][77][78][79][80][81][82][83][84] . In this study, we did not visually present the object to be mentally rotated, as participants were asked to imagine a diver spinning in the air while keeping their eyes closed.…”
