Multisensory Gamma Entrainment

EEG

EEG dataset from a single healthy young adult examining how auditory, visual, and combined audio-visual stimulation entrain gamma-band brain oscillations. Gamma entrainment has been proposed as a therapeutic approach for Alzheimer's disease symptoms. The session consists of three 40-second stimulation epochs, using a 40 Hz amplitude-modulated auditory tone, a 20 Hz LED flicker, and both together.

Delineating neural contributions to EEG-based speech decoding

EEG Zarr

This dataset contains 128-channel EEG recordings acquired while participants produced one of five color words (green, magenta, orange, violet, yellow) under overt, minimally overt, and covert speech conditions. Each trial comprises five repetitions of the same word. Auxiliary channels (EOG, orbicularis oris EMG, microphone, display, trigger) support delineating neural versus non-neural contributions to EEG-based speech decoding. Sessions include calibration data for decoder training and online real-time decoding.

P300 BCI EEG dataset (Chailloux Peguero et al. 2020)

EEG Zarr

A P300 brain-computer interface EEG dataset from 19 healthy participants, each recorded across 3 sessions. The study examines how visual stimulation conditions, standard flash versus cartoon face stimuli, affect single-option P300-BCI performance across grid sizes of 4 to 9 symbols. Recordings use an 8-channel montage sampled at 256 Hz and include target and non-target event labels.

Free Recall with Closed-Loop Stimulation at Encoding (Encoding Classifier)

BEH iEEG Zarr

This dataset contains behavioral events and intracranial EEG recordings from a delayed free recall task with closed-loop electrical stimulation delivered during word encoding. A logistic regression classifier trained on participants' prior free recall sessions predicts subsequent recall from encoding-period neural activity, and stimulation is triggered when predicted recall is low. Data were collected at multiple clinical sites in collaboration with the Computational Memory Lab at the University of Pennsylvania.

A dataset recorded during development of a tempo-based brain-computer music interface

EEG

EEG recordings from 19 healthy participants using a music-based brain-computer interface that lets users dynamically modulate music tempo through intentional control. Participants kinaesthetically imagined squeezing a ball with the right hand to increase tempo, or relaxed to decrease it. The paradigm comprised 9 runs, beginning with a calibration run of 30 trials in pairs of increase and decrease tempo trials.
