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.

A multi-session dataset of simultaneous EEG-fMRI recorded from 24 healthy adults aged 18-35 while they performed a gradual-onset continuous performance task (GradCPT) and a resting-state condition with intermittent multidimensional experience sampling. The same protocol was repeated on two days. Carbon wire loop sensors in the EEG cap support artifact removal. The dataset also includes ECG, behavioral responses, and mental health surveys. It supports study of attentional fluctuations, mind-wandering, and the test-retest reliability of EEG-fMRI relationships.

Open-access resting-state EEG recordings from 21 neurotypical undergraduate students at the Federal University of Paraíba, Brazil, collected before and after different study methods. Participants were randomly assigned to an active learning group (retrieval practice with feedback), a passive learning group (review of lecture notes), or a control group with no review. The dataset supports research in cognitive neuroscience, educational neuroscience, and the neural correlates of learning and memory.

Simultaneous EEG and fMRI recordings from healthy volunteers who reported their confidence in the accuracy of decisions they either committed themselves or merely observed. The dataset supports analysis of postdecisional contributions to metacognition and includes raw fMRI, BrainVision EEG, T1 anatomical scans and field maps, along with preprocessed EEG and fMRI derivatives.

EEG dataset investigating the neural representation of consciously seen and unseen information. The recordings were collected by Rodríguez-San Esteban, Chica, and González-López and are shared in BIDS format. The dataset is mirrored on NEMAR from OpenNeuro (ds005273).

This dataset contains EEG/ERP recordings from a randomized controlled trial comparing forward span training, backward span training, and no-intervention control groups on working memory. Recordings were collected at pre-, mid-, and post-test while participants performed a distractor version of the change detection task, and behavioral data were collected from additional change detection and suppress tasks. The data support analyses of working memory maintenance and interference control, indexed by Kmax and contralateral delay activity (CDA).

Simultaneous EEG-fMRI dataset from 18 participants who played two games (a face game and a maze game) during wakefulness in a 3T MRI scanner. One game was randomly assigned to be won (reward) and the other lost (no reward). Participants then slept in the scanner with 64-channel EEG for 1-2 hours. A classifier trained on game-session data was applied to sleep-session fMRI to examine reward-biased spontaneous neural reactivation, and memory for both tasks was tested the next day.

EEG dataset recorded while participants performed a visual working memory task in virtual reality using a head-mounted display. Memory items (a bowl, cup, plate and teapot) were cued by either a virtual avatar or a stick, with cues that were spatially valid or invalid. Participants were probed on item location and item status. The dataset includes raw and processed EEG, behavioral data, event codes and analysis code.
