EEG recordings from a visual working memory task in healthy controls and individuals with sub-acute mild traumatic brain injury (mTBI), with mind wandering probes inserted between trials. Participants were tested across up to three sessions, from 3-14 days post-injury to roughly 4 months later, with MRI acquired only in the first session. Data were collected in 2016-2018 and have not been published in a dedicated paper.

EEG recordings from children performing letter discrimination and visual search tasks involving the mirror-image letters b and d, collected in an embodied learning for literacy study. Each participant completed a pre-intervention discrimination task, an intervention-phase visual search task, and a post-intervention discrimination task. Participants were assigned to an intervention or control group, and events mark stimulus presentation of b and d letters, including practice trials.

Preprocessed stereotactic EEG (SEEG) high-gamma power (50-100 Hz) from 16 patients with pharmaco-resistant epilepsy performing a probabilistic instrumental learning task with reward and punishment conditions. Data cover 248 bipolar derivations in the anterior insula, dorsolateral prefrontal cortex, lateral orbitofrontal cortex and ventromedial prefrontal cortex, time-locked to outcome. The derivative release supports information-theoretic analyses showing dissociable reward and punishment subsystems in the human frontal cortex.

EEG recordings from 13 healthy participants performing a copy-spelling task with a visual 6x7 matrix ERP speller. The speller was designed for learning from label proportions (LLP), an unsupervised, calibrationless classification approach for ERP-based brain-computer interfaces. Two stimulus sequences with different target/non-target ratios allowed LLP to reconstruct mean target and non-target responses without labeled data. In the original online study, 84.5% of characters were spelled correctly on average without prior calibration.

EEG dataset of a visual oddball (P300) task from the PURSUE project, collected in 2017 and 2018 from participants at three primarily undergraduate institutions in Southern California, Massachusetts, and Virginia. The task design follows the ERP CORE paradigm, and the dataset includes participant demographic information such as race.

EEG dataset recorded during rapid serial visual presentation (RSVP) of sentences with flanking words, in which the critical center word was shown between grey flanker words. Sentences contained subject-verb agreement violations, semantic violations, double violations, word-order violations, or no violation (controls). The dataset supports research on sentence processing and parafoveal word processing during reading.
