Profound neuronal differences during Exercise-Induced Hypoalgesia between athletes and non-athletes revealed by functional near-infrared spectroscopy

NIRS

This fNIRS dataset captures brain oxygenation changes during exercise-induced hypoalgesia in 22 endurance athletes and 20 non-athletes. Participants completed high-intensity interval training (HIIT) and pressure pain tests while oxyhemoglobin was recorded over the prefrontal, sensorimotor and posterior parietal cortices. The data support comparisons of athlete and non-athlete neural responses to exercise and pain, and how these relate to pain perception.

A multi-modal human neuroimaging dataset for data integration: simultaneous EEG and fMRI acquisition during a motor imagery neurofeedback task: XP1

ANAT EEG FUNC Zarr

A multi-modal neuroimaging dataset (XP1) with simultaneous 64-channel EEG and fMRI recorded while 10 participants performed right-hand kinaesthetic motor imagery with neurofeedback. Each participant completed motor localizer, pre- and post-training motor imagery runs, and three neurofeedback runs (EEG-only, fMRI-only, and bimodal EEG-fMRI). The release includes raw and preprocessed EEG, BOLD fMRI, anatomical data, and EEG and BOLD neurofeedback scores to support multi-modal data integration.

Memory Reactivation Levels Remain Unaffected by Anticipated Interference

EEG Zarr

EEG dataset from a visual working memory interference task (Experiment 1) investigating whether memory reactivation levels are affected by anticipated interference. Participants memorized a cued target object among two lateral objects; interference objects were shown in half of the blocks, followed by a probe and feedback. Preprocessing steps are described in an accompanying preprint and OSF repository referenced by the dataset authors.

Brain-wide human sEEG during aversive eyepuffs and ketamine infusion (Kauvar, Richman, Liu et al. 2025; DANDI 001347)

iEEG

Stereo-EEG (sEEG) recordings from seven adult epilepsy patients undergoing extended-stay clinical monitoring at Stanford Hospital, collected during brief aversive air puffs to the eye and around a 40-minute ketamine infusion (0.5 mg/kg). This BIDS-iEEG derivative represents the NWB data released on DANDI (001347), downsampled to 200 Hz, with 30 twenty-minute recordings and 88-206 contacts per participant. The data support study of the brain-wide emergence of emotional responses to sensory experience and their modulation by a dissociative drug.
