What is fNIRS?
Functional Near Infrared Spectroscopy (fNIRS) is a non-invasive imaging technique used to measure brain activity by detecting changes in blood flow.
How does the wearable fNIRS system work?
The system uses light to measure hemodynamic responses in the brain, allowing for monitoring during cognitive tasks in natural settings.
What are the advantages of using fNIRS?
fNIRS is portable, non-invasive, and allows for monitoring brain activity in freely moving subjects, making it suitable for ecological studies.
Can fNIRS be used in clinical settings?
Yes, fNIRS can be applied in clinical settings, such as neuro rehabilitation, to investigate the neural effects of training procedures.
What cognitive tasks were used in the study?
The study involved ecological prospective memory tasks, including counting stimuli and interacting with objects in the environment.
What insights can be gained from this research?
The research provides insights into prefrontal cortex function and cognitive processes in naturalistic environments, which may differ from laboratory settings.
