EEG and behavioral dataset from 39 Italian-speaking university students performing a picture-matching task in which target pictures matched or mismatched a preceding cue. Cues were physical (picture), imagery (single word), literal sentence, or metaphorical sentence. The data are provided as preprocessed long epochs (filtered, mastoid re-referenced, ocular ICA cleaned). The dataset was collected within the ERC PROMENADE project to test how mental representations generated by different cue types influence target picture processing. Vocabulary and mental imagery measures are included per participant.

Microwire local field potentials (200 Hz) recorded from Behnke-Fried hybrid depth electrodes in 16 patients with drug-resistant epilepsy during a cognitive-boundary memory paradigm. Participants encoded 90 silent movie clips containing no, soft, or hard event boundaries, then completed a scene-recognition test and a time-discrimination test. Recording sites include the amygdala, hippocampus, and parahippocampal gyrus, with some participants also covering the dorsal anterior cingulate, pre-SMA, and ventromedial prefrontal cortex. This is an iEEG-BIDS representation of the authors' NWB release on DANDI (000940), supporting analyses of theta phase precession and episodic memory.

EEG dataset from a visual working memory experiment (Experiment 2) examining whether memory reactivation levels are affected by anticipated interference. Participants memorized 2 or 6 lateral objects, then performed either a dual task with distractors or a single fixation-only task during the delay, before selecting the cued object in a probe display. The data have been preprocessed; the preprocessing steps are described in the associated preprint and OSF repository (Experiment 2).

This dataset, named DataSet2, is an EEG dataset originally deposited on OpenNeuro (ds002833) and mirrored on NEMAR. It was contributed by Mheich and colleagues. The available documentation gives no details on the experimental paradigm or participants.

EEG dataset of 15 healthy participants performing a four-class auditory stream segregation multiclass ERP (ASME) brain-computer interface task. Two strategies for achieving four classes were compared: ASME-4stream (four streams, one target stimulus each) and ASME-2stream (two streams, two target stimuli each). P300 responses, binary classification and offline BCI simulation with linear discriminant analysis showed average accuracies of 0.83 and 0.86, respectively. NASA-TLX workload ratings were also collected.

The MNE-Sample-Data dataset is a simultaneous MEG and 60-channel EEG recording with an accompanying structural MRI, distributed with the MNE software. Checkerboard patterns were presented to the left and right visual fields, interleaved with tones to the left or right ear, and the subject responded to occasional smiley faces. It serves as a standard example dataset for demonstrating MEG/EEG analysis workflows, and FreeSurfer-derived anatomical surfaces are included.

This dataset contains simultaneous EEG and fMRI recordings from participants performing an inner speech task, in which eight words were presented in random order and repeated across trials. Data were acquired with a 3T MRI scanner and a 64-channel BrainProducts EEG system in three subjects across two sessions each. EEG data include pulse artifact removal and are organized in BIDS format.

This dataset is the EEG and structural MRI portion of a multi-subject, multi-modal face processing study (originally ds000117), repackaged in EEGLAB format with augmented event logs and HED annotation. Eighteen participants viewed famous, unfamiliar, and scrambled faces while making symmetry judgments. The original study had two sessions (fMRI and simultaneous MEG/EEG); only the MEEG session's EEG data and the structural MRI are included here, while MEG and fMRI data are excluded. Minimal preprocessing, including EEG channel extraction, event correction, and resampling to 250 Hz, yields a lightweight version suitable for tutorials and EEG source localization.

A cross-session motor imagery EEG dataset from 14 healthy participants who performed cued left- versus right-hand motor imagery on two separate days. Data were recorded with 28 EEG channels at 250 Hz and comprise 60 trials per class per session. The dataset supports research on brain-computer interface decoding and cross-session variability, and it is distributed here in BIDS format with HED event annotations.
