This dataset comprises functional near-infrared spectroscopy (fNIRS) neuroimaging data collected during a study investigating the neural mechanisms of morphine analgesia and placebo effects. Participants received painful electrical stimulation under three conditions: baseline, morphine administration, and placebo treatment. The study measured hemodynamic responses in the medial frontopolar cortex (medial BA 10) to characterize how morphine and placebo attenuate neural responses to noxious stimuli.

This dataset comprises functional near-infrared spectroscopy (fNIRS) measurements of hemodynamic brain responses to painful thermal and electrical stimuli applied to the fingertip during a finger-tapping motor task. The study investigates the specificity of cerebral hemodynamic responses to noxious stimulation, combining neuroimaging with sensory stimulation protocols to characterize pain-related brain activation patterns.

This dataset comprises EEG recordings and behavioral data from 300 face, illusory face, and matched non-face object stimuli presented during three tasks: spontaneous dissimilarity judgments, face-likeness ratings, and face/object discrimination. Neural activity was recorded while participants performed an orthogonal target detection task during stimulus presentation at 3.75 Hz, enabling investigation of the neural correlates underlying distinct stages of spontaneous face perception.

This dataset comprises simultaneous 7T fMRI and EEG recordings from 25 native Mandarin Chinese speakers engaged in a naturalistic listening task featuring the Chinese version of Le Petit Prince under varying acoustic conditions (single-talker and multi-talker scenarios). The study investigates neural mechanisms of selective attention and speech comprehension in complex auditory environments, with participants attending to different talkers while maintaining fixation during fMRI acquisition. Preprocessed anatomical and functional MRI data, along with high-density EEG recordings, are provided in BIDS format alongside behavioral comprehension assessments. This dataset is derived from OpenNeuro ds005345 (v1.0.1) and has been curated for the NEMAR repository. Note: The README references French cohort considerations; however, the primary dataset composition consists of the 25 native Mandarin Chinese speakers described above.

This dataset comprises EEG recordings from 142 participants undergoing laser-evoked pain stimulation with concurrent pain intensity ratings. Participants received fixed-intensity nociceptive stimuli at two levels (low and high pain) across three blocks of 10 stimuli each, with pain ratings collected on a 0-10 scale after each trial. The dataset provides neurophysiological and behavioral measures of pain perception suitable for investigating the neural correlates of pain processing.
