High-density (127-channel) EEG recordings from 30 healthy, right-handed, native Chinese-speaking adults performing imagined and executed vocalization and writing tasks. Stimuli were four Chinese strokes (heng, shu, pie, na) and four English letters (a, b, c, d). The factorial design crossed task mode, action, script and token identity, yielding 32 event-coded conditions and 15,360 task events. The release also includes EEGLAB preprocessing derivatives and subject-level machine-learning exports.

A multi-modal face processing dataset combining simultaneously recorded MEG and EEG with structural MRI from 18 participants. Participants viewed famous, unfamiliar, and scrambled faces and made a symmetry judgment by button press. The data are a curated repackaging of the MEEG portion of ds000117, with reorganized event logs, Hierarchical Event Descriptor (HED) annotations, and EEGLAB-format EEG.

PsiConnect is a multimodal neuroimaging dataset examining context-dependent neural and subjective effects of psilocybin in 62 participants scanned before and after a 19 mg dose. It combines multi-echo functional, structural and diffusion-weighted MRI with EEG during resting state and three naturalistic conditions (guided meditation, music listening, movie watching). Half of the cohort completed an 8-week meditation training program. Behavioural and self-report measures with follow-ups up to one year support study of acute and longitudinal effects.

EEG recordings from 33 participants who each completed both a visual and an auditory surprise task, with task order counterbalanced. The dataset supports investigation of electrophysiological markers of surprise-induced failures of visual and auditory awareness. Data from participants excluded at various analysis stages are included up to the stage of processing they reached.

EEG dataset from a visual search task eliciting the N2pc event-related potential, collected as part of the PURSUE project. Participants were recruited at three primarily undergraduate institutions (Southern California, Massachusetts, and Virginia) in 2017 and 2018. The task follows the ERP CORE paradigm.
