MoBILAB: an open source toolbox for analysis and visualization of mobile brain/body imaging data

Area of Science:

• Neuroscience
• Cognitive Science
• Biomedical Engineering

Background:

• Mobile Brain/Body Imaging (MoBI) enables synchronous recording of brain activity (EEG) and behavior (motion capture, eye tracking).
• Studying joint brain/body dynamics is crucial for understanding natural human cognition and actions in 3-D environments.
• Existing signal-processing tools are inadequate for complex, multi-modal, multi-rate data streams inherent in MoBI.

Purpose of the Study:

• Introduce MoBILAB, an open-source MATLAB toolbox for analyzing MoBI data.
• Provide a platform for processing and visualizing mixed, synchronously recorded brain, behavioral, and environmental data.
• Facilitate pre-processing and expanded analysis of MoBI datasets.

Main Methods:

• Developed MoBILAB, a cross-platform toolbox for MATLAB.
• Integrated analysis and visualization of synchronous multi-modal time series data (EEG, motion, eye-tracking, environmental).
• Supported time-marked event stream data alongside continuous recordings.

Main Results:

• MoBILAB offers a unified environment for diverse MoBI data streams.
• The toolbox supports pre-processing, including adding event markers to EEG data.
• Enables expanded analysis of simultaneously recorded brain and behavioral data.

Conclusions:

• MoBILAB provides a versatile solution for the complex data processing demands of MoBI.
• The toolbox enhances the study of brain-body dynamics during naturalistic cognition and interaction.
• MoBILAB serves as a valuable resource for researchers in neuroscience and cognitive science.
