A BIDS-converted neuroimaging dataset containing time-series fNIRS data from 18 subjects across two sessions. The dataset includes near-infrared spectroscopy (NIRS) measurements with independent component analysis (ICA) denoising applied. Data were collected using continuous-wave NIRS with simultaneous measurement of oxygenated and deoxygenated hemoglobin concentrations. This dataset is derived from TimeSeriesHbORT_18sub_twoSessionICAdenoise and has been reformatted to comply with BIDS standards. NOTE: This dataset is currently under validation. Critical NIRS metadata fields (SamplingFrequency, NIRSChannelCount, source/detector mapping) and BIDS compliance must be confirmed before public release.

This high-density functional near-infrared spectroscopy (fNIRS) dataset comprises neuroimaging recordings from the motor cortex during three experimental paradigms: resting state, ball-squeezing motor tasks (both hands performed sequentially), and purposeful motion artifact creation. The dataset includes concurrent accelerometer measurements and is designed to support the development and validation of motion artifact correction algorithms in fNIRS neuroimaging.

This functional near-infrared spectroscopy (fNIRS) dataset investigates neuronal mechanisms underlying exercise-induced hypoalgesia in endurance athletes versus non-athletes. Twenty-two athletes and twenty non-athletes performed high-intensity interval training (HIIT) while brain oxygenation was monitored across pain-processing regions including the prefrontal cortex, sensorimotor cortices, and posterior parietal cortex. The study reveals distinct neural activation patterns and pain reduction responses between groups, with athletes demonstrating greater oxyhemoglobin increases in the posterior parietal cortex during exercise and significant post-HIIT decreases in pain perception correlated with prefrontal cortex deactivation.

This dataset comprises resting-state and auditory oddball task electroencephalography (EEG) recordings from older adults under two experimental conditions: control and threat-of-shock arousal. Participants completed eyes-open and eyes-closed resting periods, as well as passive and active auditory oddball tasks with standard, target, and distractor tones. The data were collected as part of the HeartBEAM study investigating locus coeruleus-noradrenaline system function and its relationship to attention and memory in aging.
