Based on neurovascular coupling, fNIRS is able to measure the haemoglobin concentration changes secondary to neuronal activity. Compared to other neuroimaging techniques, fNIRS represents a good compromise in terms of spatial and temporal resolution. Moreover, it is portable, lightweight, less sensitive to motion artifacts and does not impose significant physical restraints. It is therefore appropriate to monitor a wide range of cognitive tasks (e.g., auditory, gait analysis, social interaction) and different age populations (e.g., new-borns, adults, elderly people). The recent development of fiberless fNIRS devices has opened the way to new applications in neuroscience research. This represents a unique opportunity to study functional activity during real-world tests, which can be more sensitive and accurate in assessing cognitive function and dysfunction than lab-based tests. This study explored the use of fiberless fNIRS to monitor brain activity during a real-world prospective memory task. This protocol is performed outside the lab and brain haemoglobin concentration changes are continuously measured over the prefrontal cortex while the subject walks around in order to accomplish several different tasks. date: 2015 official_url: http://dx.doi.org/10.3791/53336 oa_status: green full_text_type: pub pmcid: PMC4692764 primo: open primo_central: open_green article_type_text: JOURNAL ARTICLE verified: verified_manual elements_id: 1068597 doi: 10.3791/53336 language_elements: ENG lyricists_name: Burgess, Paul lyricists_name: Gilbert, Sam lyricists_name: Hamilton, Antonia lyricists_name: Pinti, Paola lyricists_name: Tachtsidis, Ilias lyricists_id: PWBUR01 lyricists_id: SJGIL27 lyricists_id: AFDCH84 lyricists_id: PPINT49 lyricists_id: ITACH19 actors_name: Poirier, Elizabeth actors_id: EPPOI23 actors_role: owner full_text_status: public publication: Journal of Visualized Experiments volume: 106 issn: 1940-087X citation: Pinti, P; Aichelburg, C; Lind, F; Power, S; Swingler, E; Merla, A; Hamilton, A; ...
