Exploring Neural Efficiency in Spatial Cognition: A Comparative Study @NIRxMedicalTechnologies

Uploaded July 2025 | Updated September 2026, 1 hour ago

Spatial cognition is an essential component of our daily lives, and Dr. da Silva's work delves into the connection between spatial abilities and performance in academic disciplines, particularly within the STEM fields. His research utilizes a cost-effective virtual reality (VR) headset combined with functional near-infrared spectroscopy (fNIRS) to objectively evaluate spatial cognition during mental rotation tasks (MRT) in both 3D and 2.5D conditions.

The findings from this study indicate important differences in neural efficiency between STEM and non-STEM individuals, revealing that those in STEM fields demonstrate greater efficiency in the dorsolateral prefrontal cortex while engaging with MRT in a VR environment. Importantly, the results suggest that 3D and 2.5D stimuli offer equally viable options for exploring cognitive skills in VR settings.

$NIRxBorealis - Translating fMRI to fNIRS Introducing the NIRxBorealis for fNIRS data acquisition in an MRI environment! NIRx custom builds the NIRxBorealis to combine the NIRx flagship NIRSport2 amplifiers with fiber-based laser stimulation and ADP detectors. This allows concurrent fMRI and fNIRS recordings and then the co-analysis of fNIRS and fMRI results. It also allows directly running the very same fNIRS experiment fully mobile outside the scanner at a fraction of the cost. https://nirx.net/borealis$
