HAD-MEEG is a multimodal neuroimaging dataset combining magnetoencephalography (MEG) and electroencephalography (EEG) recordings from 30 participants viewing 21,600 video clips across 180 human action categories. Designed to complement the previously released HAD-fMRI dataset, this resource leverages the millisecond-level temporal resolution of M/EEG to capture rapid neural dynamics underlying action recognition and social cognition, enabling integrated spatiotemporal analysis of brain responses to visual action stimuli.

This dataset contains EEG recordings and structural MRI scans from patients undergoing stereotactic focused ultrasound mesencephalotomy for the treatment of head and neck cancer pain. The study evaluates neurophysiological responses during this minimally invasive neurosurgical procedure. Data were collected from multiple subjects and organized according to BIDS standards (version 1.8.0). The dataset includes raw EEG data acquired during the procedure and structural anatomical MRI images. Processing was performed using EEG-BIDS (v10.3) and dicm2nii (v20250821) tools.

EEGEyeNet is a simultaneous electroencephalography and eye-tracking dataset designed for eye movement prediction research. This BIDS-standardized dataset contains raw EEG and eye-tracking recordings collected from human subjects during controlled experimental tasks. The dataset serves as a benchmark for developing and evaluating computational models of eye movement behavior using multimodal neuroimaging data.

This dataset comprises EEG recordings from an auditory oddball experiment designed to investigate how personalized smartphone notifications modulate auditory salience processing across different neural processing stages. The study examines the effects of notification-induced attention shifts on the neural representation of task-relevant and task-irrelevant auditory stimuli. Data were collected from multiple participants using a standardized oddball paradigm with smartphone notification manipulations to assess changes in event-related potentials and other EEG markers of auditory processing.

This dataset comprises EEG recordings from two patients with chronic post-stroke anomia who underwent an 8-week individualized transcranial alternating current stimulation (tACS) intervention. Using a single-case experimental design with alternating stimulation and non-stimulation phases, the study investigated whether personalized tACS guided by individual EEG profiles could enhance naming abilities through cortical entrainment. EEG data were collected during picture naming tasks at weekly intervals, with behavioral and electrophysiological measures assessed across 24 naming sessions and 6 EEG recording sessions per participant.

This dataset comprises high-density EEG recordings from 15 healthy young adults during treadmill walking at multiple speeds (0.0–1.6 m/s) with intermittent visual occlusions induced by liquid crystal lens goggles. The study investigates neurophysiological responses to visual processing disruptions during gait by measuring electrocortical alpha synchronization. Concurrent recordings include EMG, ground reaction forces, and inertial measurement unit data to characterize the sensorimotor context of visual processing during locomotion. NOTE: This dataset represents a subset of a larger protocol containing 13 additional conditions. Some participants have incomplete or missing Loadsol insole sensor data (sub-05, sub-06, sub-07) and IMU data (sub-02, sub-04, sub-06, sub-12). One participant (sub-01) is missing part of the noise sensor array.

This dataset comprises EEG recordings from 84 healthy participants performing motor imagery tasks across multiple controlled environments (laboratory and simulated hospital), with a supplementary cohort of 3 participants recorded in microgravity conditions in a space station environment. The dataset includes multiple motor imagery paradigms (Graz, SSMVEP-MI, and hybrid variants) with 64-channel EEG recordings at 1000 Hz sampling rate (69 channels acquired, 60 channels used in analysis), designed to investigate environmental effects on brain-computer interface performance and enable cross-environment robustness evaluation. This dataset is a republication of OpenNeuro ds007221 on the NEMAR platform to enhance accessibility and discoverability within the neuroimaging research community.

This multi-session dataset comprises simultaneous EEG-fMRI recordings from 24 healthy adults (ages 18-35) performing a sustained attention task (GradCPT) and resting state with online experience sampling. The dataset includes 31-channel cortical EEG (plus 4 carbon wire loop sensors and 1 ECG channel for a total of 36 recorded channels) with carbon wire loop sensors for artifact removal, concurrent fMRI, ECG, behavioral responses, and multi-dimensional experience sampling ratings assessing thought contents and processes. Approximately 1 hour 20 minutes of data were collected per participant per session across two sessions, enabling investigation of neural correlates of spontaneous cognitive processes including mind-wandering and attentional fluctuations. All structural MRI images were defaced for privacy. Note: One session (sub-003_ses-001) contains incomplete data collection with 3 runs instead of the standard 4 runs due to time constraints.

This dataset comprises resting-state and task-based EEG recordings from 100 participants designed to investigate hemispheric asymmetries in electroencephalographic activity. The study examines the association between N1 lateralization and alpha asymmetry across multiple cognitive domains including word recognition, face processing, emotion perception, and visual object categorization. Participants completed approximately 8 minutes of resting-state EEG with alternating eyes-open and eyes-closed periods, followed by four randomized tasks involving stimulus-response paradigms with counterbalanced hand responses.

This multimodal dataset comprises synchronized EEG, ECG, and pupillometry recordings from 18 participants performing an n-back working memory task with four difficulty levels (1-back through 4-back). The study employed a combined mobile EEG+ECG system and Pupil Labs eye tracker synchronized via Lab Streaming Layer, capturing cognitive workload modulation across task difficulty. Raw XDF recordings were converted to BIDS format with EEG in BrainVision format, pupil data exported as TSV files, and task events aligned to EEG start time. The dataset includes 19-channel EEG at 250 Hz, 3-lead ECG, and asynchronous pupil tracking, with detailed task event annotations and participant exclusion metadata.
