Summary
Virtual reality (VR) games in MRI scanners show different brain connectivity via goggles versus screens. Stereoscopic VR goggles enhance connectivity more than monoscopic VR, suggesting suitability for brain training.
Area of Science:
- Neuroscience
- Medical Imaging
- Virtual Reality Technology
Background:
- Virtual reality (VR) offers immersive experiences, enhancing skill transfer to real-world situations.
- VR is utilized in education, psychotherapy, and rehabilitation, showing potential for training interventions.
- Investigating VR's use within Magnetic Resonance Imaging (MRI) scanners is crucial for understanding its neurological impact.
Purpose of the Study:
- To assess VR goggle use within MRI scanners for brain connectivity analysis.
- To compare brain connectivity differences between VR goggles and screen-based stimulation.
- To determine if stereoscopic VR elicits stronger brain connectivity than monoscopic VR.
Main Methods:
- Utilized fractional low-frequency fluctuation, independent component analysis (ICA), seed-based FC (SeedFC), and graph analysis.
- Compared brain activation and functional connectivity (FC) between VR goggle (monoscopic and stereoscopic) and screen presentations.
- Focused on visual and default mode networks (DMN) for connectivity analysis.
Main Results:
- VR goggles (mono/stereoscopic) vs. screen showed brain activation differences in the left cerebellum and postcentral gyrus.
- Connectivity differences were observed in the visual and frontal inferior cortex.
- Stereoscopic VR goggles demonstrated higher connectivity between the superior frontal cortex, insula/putamen compared to monoscopic VR.
Conclusions:
- VR goggle stimulation, particularly stereoscopic, elicits stronger brain connectivity than screen-based presentation within an MRI.
- Findings suggest VR goggle use in MRI is suitable for brain training interventions.
- Enhanced brain connectivity via VR may lead to long-term functional and structural brain improvements.

Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

01:24Facial Feedback Hypothesis

Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...
