This dataset contains EEG recordings from 14 healthy participants performing a covert attention task with real-time neurofeedback based on alpha power lateralization. The study investigates whether real-time EEG feedback on alpha power lateralization can lead to behavioral improvements in a covert attention task, employing a single-blinded crossover design comparing real versus sham feedback conditions across three recording sessions.

This dataset contains MEG recordings from a binocular rivalry experiment conducted in early 2014. Participants were presented with competing visual patterns while neural activity was recorded, with event markers capturing trial structure, stimulus presentations, and behavioral responses including manual tapping and perceptual reports of rivalry dominance. Anatomical MRI data is also included for each participant.

PsiConnect is a large-scale multimodal neuroimaging study investigating context-dependent neural and subjective effects of psilocybin in 62 participants. The dataset combines functional, structural, and diffusion-weighted MRI with concurrent EEG acquired before and after psilocybin administration (19 mg), incorporating resting-state and naturalistic conditions (guided meditation, music listening, movie watching). Half the cohort completed an 8-week meditation training program to examine interactions among meditation, psilocybin, and brain function, with comprehensive behavioral assessments and follow-ups extending to one year post-administration. Data is curated according to open science principles to ensure accessibility and compatibility with established neuroimaging pipelines.

This dataset comprises resting-state transcranial magnetic stimulation (TMS) combined with electroencephalography (EEG) recordings from multiple subjects. The study focuses on identifying site- and stimulation-specific TMS-evoked EEG potentials using quantitative cosine similarity metrics to characterize the electrophysiological responses to TMS across different brain regions.

This dataset comprises concurrent EEG and transcranial direct current stimulation (tDCS) recordings from 40 participants performing an attentional blink task. Participants completed two laboratory sessions approximately one week apart, receiving either anodal or cathodal tDCS (1 mA, 20 minutes) while EEG was recorded before, during, and after stimulation. The dataset documents the physiological effects of tDCS on neural correlates of attention and provides a resource for investigating artifact characteristics in concurrent tDCS-EEG recordings.

This dataset contains electroencephalographic (EEG) and electrocorticographic (ECoG) recordings from twenty healthy participants and one patient with intractable epilepsy during a tactile detection task with confidence reporting. The study investigates the relationship between evidence accumulation, perceptual consciousness, and metacognitive monitoring using vibrotactile stimuli applied to the wrist with adaptive stimulus intensity. Data were acquired using 62-channel EEG (10-20 montage) at 1024 Hz for healthy subjects and 24-channel ECoG at 2048 Hz for the patient.

This dataset comprises electroencephalographic recordings from 32 participants performing motor imagery tasks during sit-to-stand and stand-to-sit transitions in both offline and online brain-computer interface (BCI) paradigms. Participants completed guided motor imagery trials while seated or standing, with EEG signals recorded from 17 channels at 250 Hz. The dataset includes offline calibration phases used to train machine learning classifiers and corresponding online validation phases where real-time BCI decoding was performed, providing a comprehensive resource for investigating neural correlates of postural transitions and BCI performance.

The OMEGA Resting State Sample Dataset comprises magnetoencephalography (MEG) recordings from 5 subjects during 5-minute eyes-open resting state sessions acquired at the Montreal Neurological Institute using a CTF 275 system. The dataset includes high-resolution MEG data (297+ channels at 2400 Hz sampling rate), structural T1-weighted MRI images processed with FreeSurfer, 3D head digitization, and fiducial point information organized according to the MEG-BIDS specification. This resource serves as a reference dataset for MEG preprocessing, analysis methodology development, and neuroimaging research.

A single-subject MEG dataset acquired during an auditory oddball task using a CTF 275 system at 2400 Hz sampling rate. The dataset includes two 6-minute runs with 200 standard tones (440 Hz) and 40 deviant tones (554.4 Hz) presented binaurally, along with behavioral responses, empty room recordings, anatomical MRI, and detailed head digitization. This dataset serves as a tutorial example for the Brainstorm neuroimaging software and is widely used for MEG analysis demonstrations.
