Enhancing Brain Health and Cognitive Development Through Sensorimotor Play in Virtual Reality: Uncovering the Neural Correlates

This paper, authored by researchers at the Bulgarian Academy of Sciences' Institute of Robotics, examines whether sensorimotor play in virtual reality can support brain health and cognitive development. It frames sensorimotor integration as a driver of neural growth, linking VR-based play to brain-derived neurotrophic factor activity, executive function, and neuroplasticity. Its stated aims are to review neuroscientific evidence from fMRI, fNIRS, EEG, PET, and MEG studies and to propose a Brain-Computer Interface-based conceptual model for personalized VR game design.

The reviewed evidence points to several recurring findings. EEG studies associate VR-based sensorimotor and motor-imagery training with increased beta and mu-rhythm activity, while neurofeedback research links frontal alpha and sensorimotor rhythm power to better attentional control and memory. Imaging studies report VR-related increases in cortical gray matter volume and activation of prefrontal, premotor, and mirror-system regions during emotion regulation and action observation. The authors caution that most cited effects come from small samples and their own interpretations, so causal and clinical claims remain preliminary.

The central contribution is a conceptual model in which EEG, fNIRS, MEG, EMG, and pupil tracking assess visuomotor integration, visuoauditory integration, and emotional states, allowing VR games to adapt toward targeted neuroplastic outcomes. The paper presents no new empirical validation, reports no outcome data, and acknowledges that generalizability, transfer of VR-learned skills to real-world settings, and standardization of evaluation protocols are unresolved.
