New software dedicated to virtual mazes for human cognitive investigations

Area of Science:

• Neuroscience
• Cognitive Psychology
• Virtual Reality Technology

Background:

• Traditional neuropsychological tests using paper-pen methods have limitations in assessing complex spatial learning and memory.
• 3-D virtual immersive technology presents novel opportunities for research and clinical diagnosis of mild cognitive impairment and dementia.

Purpose of the Study:

• To develop VRmaze software, an advanced tool for spatial learning and memory research.
• To offer customizable virtual reality environments for both research and clinical applications.

Main Methods:

• The VRmaze software integrates 3D pre-calibrated virtual reality (VR) tests and customizable VR tests.
• It also incorporates digitized 2D neuropsychological tests and tasks with automatic tracking and analysis.
• The software was tested on 44 healthy subjects using ERAM, MWM, and reverse T-maze paradigms.

Main Results:

• Gender differences in navigation strategies were observed in healthy subjects.
• The study highlighted that benchmark selection, instructions, and experimental parameters significantly influence performance in VR-based cognitive tasks.

Conclusions:

• VRmaze software facilitates a translational approach, bridging animal models and human patient evaluations.
• It enables the combination of complex 3D tasks with standardized neuropsychological tests, offering automated analysis for neuroscientific research.
• A clinical module with preconfigured tasks will aid clinicians in routine patient evaluation.
