Journal ArticleDOI
Optical brain monitoring for operator training and mental workload assessment.
TL;DR: Results indicate that fN IR measures are sensitive to mental task load and practice level, and provide evidence of the fNIR deployment in the field for its ability to monitor hemodynamic changes that are associated with relative cognitive workload changes of operators.
Journal ArticleDOI
Continuous monitoring of brain dynamics with functional near infrared spectroscopy as a tool for neuroergonomic research: empirical examples and a technological development
Hasan Ayaz,Banu Onaral,Kurtulus Izzetoglu,Patricia A. Shewokis,Ryan McKendrick,Raja Parasuraman +5 more
TL;DR: In this article, the authors describe neuroergonomic studies that illustrate the use of functional near infrared spectroscopy (fNIRS) in the examination of training-related brain dynamics and human performance assessment.
Journal ArticleDOI
Using MazeSuite and Functional Near Infrared Spectroscopy to Study Learning in Spatial Navigation
Hasan Ayaz,Patricia A. Shewokis,Adrian Curtin,Meltem Izzetoglu,Kurtulus Izzetoglu,Banu Onaral +5 more
TL;DR: The goal here is to illustrate the experimental protocol design process and the use of MazeSuite, and to demonstrate the setup and deployment of the fNIR brain activity monitoring system using Cognitive Optical Brain Imaging (COBI) Studio software.
Proceedings ArticleDOI
Sliding-window motion artifact rejection for Functional Near-Infrared Spectroscopy
TL;DR: A simple and iterative method is developed that can be used to automate the preprocessing of data to identify segments with such noise for exclusion and this method is also suitable for real time applications.
Journal ArticleDOI
Measuring speaker-listener neural coupling with functional near infrared spectroscopy.
Yichuan Liu,Elise A. Piazza,Erez Simony,Patricia A. Shewokis,Banu Onaral,Uri Hasson,Hasan Ayaz,Hasan Ayaz,Hasan Ayaz +8 more
TL;DR: Functional near-infrared spectroscopy can be used for investigating brain-to-brain coupling during verbal communication in natural settings and a significant relationship between the fNIRS oxygenated-hemoglobin concentration changes and the fMRI BOLD in brain areas associated with speech comprehension is found.
