EEG dataset from 19 participants performing a visual P300 speller-like paradigm to assess how visual stimulus properties affect evoked responses and classification accuracy. Each participant completed three sessions with conditions varying the number of stimuli (4 to 9) and the flash type (standard flash versus a superimposed yellow smiling cartoon face). Recordings comprise 382 files from eight electrodes sampled at 256 Hz, with markers encoding trial phases and activated symbols.

Stereo-EEG recordings from six patients with medically refractory epilepsy performing a scene recognition memory task with concurrent EyeLink eye tracking. The dataset accompanies a study of how the human hippocampus rapidly coordinates effective learning, and is a lossless iEEG-BIDS re-packaging of the authors' public Zenodo release. It includes electrode MNI coordinates, behavioural arrays, eye-tracking files and the authors' analysis code in sourcedata.

Microwire local field potentials (400 Hz) from Behnke-Fried hybrid depth electrodes in 35 patients with drug-resistant epilepsy, recorded during a picture-based Sternberg working-memory task with load 1 or load 3. Recording sites include the hippocampus, amygdala, dorsal anterior cingulate cortex, pre-supplementary motor area and ventromedial prefrontal cortex. This is an iEEG-BIDS representation of the NWB data released on DANDI (000673) from the Daume et al. 2024 study, with signal values unchanged.

The YOTO (You Only Think Once) dataset is a human EEG resource for studying multisensory perception and mental imagery. Twenty participants completed tasks with unimodal and multimodal (visual, auditory, and combined) cues while EEG was recorded at 1000 Hz, and they gave self-reported vividness ratings of their imagery. Technical validation with event-related potentials and power spectral density analyses confirmed data reliability and distinct neural responses across stimuli, supporting research on neural decoding, perception, and cognitive modeling.

EEG recordings from 15 healthy participants performing a P300-based brain-computer interface task for controlling a home appliance, specifically a door lock. Data were acquired with 31 active EEG channels at 500 Hz during a four-class visual oddball paradigm presented on an LCD display, with target and non-target flashes. Each subject completed 50 training and 30 testing blocks, including online testing with visual feedback.
