EEG dataset investigating whether images of stylized (cartoon-like) faces with exaggerated visual features improve event-related potential (ERP) correlates of emotion relative to ordinary human faces. The stylized faces elicit an enhanced N170 component associated with facial recognition encoding. The findings suggest that consistent stimulus transformations could improve affect detection from EEG in affective brain-computer interface design.
EEG dataset from a picture-word interference (PWI) picture-naming experiment conducted at the NeuroCognition Laboratory at San Diego State University. Participants named line drawings preceded by English distractor words that were semantically related, identical in name, or unrelated to the picture, while EEG and verbal responses were recorded. The dataset supports investigation of the neural correlates of lexical access and semantic interference during speech production.

EEG recordings from twenty participants who learned three temporal intervals (short, medium, long). Two randomly interleaved subtasks were used: a Production task, in which participants produced a target interval, and a Perception task, in which they judged whether a computer-generated interval was correct. Visual feedback (checkmark or x) followed both tasks. The dataset supports investigation of temporal scaling of human scalp-recorded potentials.

Intracranial EEG (ECoG) recordings from 14 epilepsy patients implanted with clinical surface and depth electrodes, with two patients also carrying high-density research grids. Participants viewed grayscale pattern stimuli and color images of several categories. Stimuli varied in spatial and temporal properties, including pRF mapping bars, spatial and temporal patterns, and six-category localizers. Pre-implantation T1 MRI, FreeSurfer surface reconstructions and derivative broadband and preprocessed data are included.

This dataset contains 64-channel EEG recorded at 1000 Hz from 31 healthy participants performing a row/column P300 speller task with 4L and 5L grid sizes. Each participant completed three sessions. It is the P300 component of a multimodal eye-BCI collection that also includes eye-tracking and high-speed video for analyzing ocular activity across BCI paradigms. Events are annotated with HED tags as Target and NonTarget flashes.
