In contrast, functional near-infrared spectroscopy (f NIRS) has been suggested as an alternative tool for functional neuroimaging. f NIRS is an optical neuroimaging technique that allows the measurement of changes in brain tissue concentrations of oxyhemoglobin (Hb O2), deoxyhemoglobin (Hb R), and total hemoglobin (Hb T) within the brain, achieved by irradiating the head with near-infrared (NIR) light [11,12].

As brain imaging technology advances, a great deal of functional mapping information on the human brain has been accumulated from positron emission tomography (PET), functional magnetic resonance imaging (f MRI), and functional near-infrared spectroscopy (f NIRS). Among these technologies, f NIRS can measure brain activity in a noninvasive and safe manner through measuring changes in the hemoglobin oxygenation state of the human brain [15].

In the final part of the study, neural data were collected using the mobile neuroimaging method of functional near-infrared spectroscopy (f NIRS). In an event-related experimental paradigm, the online pharmacies were shown to participants as screenshots with the medications they had to search for in the first task.

In this study, we examined changes and responses in brain frontal region activities using functional near-infrared spectroscopy (f NIRS). f NIRS can be used to examine the functional activity in certain areas of the brain by measuring changes in the concentrations of oxygenated hemoglobin (Hb O2) and deoxygenated hemoglobin (Hb R) in brain tissue to assess neurological activation. f NIRS is safe, portable, and easy to use compared with neuroimaging tools such as functional magnetic resonance imaging (f MRI) [30].

In related work, examining neural activity during surgery, Ohuchida et al [25] used functional near-infrared spectroscopy (f NIRS) to demonstrate that trainees with no experience of an endoscopy task had higher oxyhemoglobin demands in the frontal cortex of the brain than expert surgeons. f NIRS is a technique that uses a series of near-infrared light sources and detectors across the surface of the scalp to measure levels of oxygenated and deoxygenated blood in specific regions of the brain.
