Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Human-Computer Interaction

Background:

  • Functional near-infrared spectroscopy (fNIR) offers noninvasive, portable brain monitoring for cognitive tasks.
  • Prefrontal cortex (PFC) activation patterns change with task novelty, practice, and retention.
  • Contextual interference (random vs. blocked practice) influences learning and memory consolidation.

Purpose of the Study:

  • To illustrate experimental protocol design using MazeSuite for spatial navigation tasks.
  • To demonstrate the setup and deployment of fNIR brain monitoring with COBI Studio software.
  • To assess PFC cognitive activity during maze learning under blocked and random practice conditions.

Main Methods:

  • Utilized MazeSuite for designing and presenting virtual 3D mazes.
  • Employed fNIR via COBI Studio to record brain activity during task performance.
  • Collected behavioral data on task acquisition, retention, and transfer across four days.

Main Results:

  • The study provides a methodological guideline for integrating virtual environments and neuroimaging.
  • Demonstrated the feasibility of monitoring PFC activity during complex cognitive tasks.
  • Reported on the distinct brain activation patterns associated with different practice schedules.

Conclusions:

  • MazeSuite and fNIR provide a robust system for studying cognitive processes in ecologically valid settings.
  • The combined approach facilitates detailed analysis of brain-behavior relationships in learning.
  • This methodology can be applied to a wide range of cognitive and neuroscience research.
