Near-infrared spectroscopy (NIRS) allows non-invasive brain imaging during movement by measuring hemodynamic responses. This technique offers insights into brain activity during motor and cognitive tasks, particularly in sport sciences.

Area of Science:

Neuroscience
Biomedical Engineering
Sport Science

Background:

Optical methods like near-infrared spectroscopy (NIRS) enable assessment of physiological changes linked to brain activity.
NIRS is a non-invasive neuroimaging technique utilizing hemodynamic principles to study the brain during motion.

Purpose of the Study:

To examine perturbation methods for measuring human cerebral hemodynamic responses during rest and exercise.
To explore the application of NIRS in imaging the moving brain, particularly in human movement sciences and sport sciences.

Main Methods:

Utilizing near-infrared light penetration for non-invasive assessment of brain activity.
Employing NIRS for dynamic changes in localized brain regions or functional brain imaging based on channel usage.
