fNIRS Insights

What is fNIRS?

Functional near-infrared spectroscopy (fNIRS) is a non-invasive neuroimaging technique that measures brain activity through changes in cerebral blood flow. It uses near-infrared light to detect changes in the concentrations of oxygenated and deoxygenated hemoglobin, which are correlated with neural activity. fNIRS is commonly used in cognitive neuroscience, psychology, and clinical research to study brain function in various tasks and conditions, such as language processing, motor control, and neurodevelopmental disorders. It is also used in brain-computer interfaces and neurorehabilitation.

What other technologies are related to fNIRS?

fNIRS Competitor Technologies

EEG

EEG is a competitor because it also measures brain activity non-invasively, though using electrical signals instead of blood flow changes, and with higher temporal resolution but lower spatial resolution than fNIRS.

fMRI

fMRI is a competitor because it measures brain activity through blood flow changes, similar to fNIRS, but with higher spatial resolution and at a greater cost and less portability.

fNIRS Complementary Technologies

eye-tracking

Eye-tracking is complementary as it can provide additional behavioral data that can be correlated with brain activity measured by fNIRS to provide a more complete understanding of cognitive processes.

TMS

TMS is complementary as it can be used to stimulate specific brain regions while fNIRS measures the resulting changes in brain activity, allowing for causal inferences.
