This non-invasive imaging tool measures brain activity by monitoring changes in blood oxygen levels, allowing us to explore neural processes in real-time. Our new fNIRS system will support a wide range of studies, from individual block and event-related paradigms to advanced social interaction research using hyperscanning procedures.<\/p>\n<p>We\u2019ve also added two new fNIRS sets \u2014 one with an integrated accelerometer for motion logging and one without. Both support configurations of up to 16 sources and 16 detectors, allowing flexible, high-density montages across target regions. Each set is equipped with four short-distance (short-separation) detector bundles to improve cortical specificity by modeling and removing superficial scalp signals.<\/p>\n\n\n\n<\/div>\n      \n
