BCI-FIT is a customization protocol dataset for non-implantable communication brain-computer interface (cBCI) systems, comprising EEG recordings from five participants with speech and/or physical impairments due to amyotrophic lateral sclerosis (ALS). Participants completed calibration and copy-spelling tasks using both customized and non-customized versions of a cBCI system across multiple visits, with iterative system adjustments based on performance, preferences, and signal characteristics. The dataset includes EEG data collected using dry electrode caps (DSI-Flex or DSI-24) sampled at 300 Hz during Matrix and RSVP typing paradigms.

EEG dataset containing recordings from participants engaged in natural conversation. The dataset includes raw EEG data collected during spontaneous speech interactions, designed to investigate neural correlates of communication and language processing. Data were acquired using standard EEG recording protocols and include multiple channels of continuous EEG activity synchronized with behavioral and linguistic annotations.

This dataset comprises 128-channel EEG recordings from 19 patients with psychosis and 24 healthy controls performing the Ultimatum Game at Fribourg University. Participants engaged in both proposer and responder roles across three blocks of 30 trials each, providing neurophysiological insights into decision-making and social cognition in schizophrenia spectrum disorders.

This dataset contains EEG recordings from a flanker word/pseudoword lexical decision task collected at the NeuroCognition Laboratory in San Diego. Participants viewed four-letter real words and pseudowords flanked by identical, different, or no flanking words, while EEG was recorded to examine neural responses associated with lexical processing under flanker conditions. The dataset was collected under San Diego State University's IRB oversight.

PsiConnect is a large-scale multimodal neuroimaging study investigating context-dependent neural and subjective effects of psilocybin in 62 participants. The dataset combines functional, structural, and diffusion-weighted MRI with concurrent EEG acquired before and after psilocybin administration (19 mg), incorporating resting-state and naturalistic conditions (guided meditation, music listening, movie watching). Half the cohort completed an 8-week meditation training program, enabling investigation of interactions between meditation, psilocybin, and brain function. Comprehensive behavioral and self-report measures were collected acutely and longitudinally up to one year post-administration.

This magnetoencephalography (MEG) dataset investigates the differential neural mechanisms underlying selection and maintenance of information during working memory tasks. Data from 22 participants include MEG recordings across two sessions, structural MRI, and detailed behavioral measures from a working memory task and a one-back control task involving visual Gabor stimuli. The dataset supports investigation of how the brain selectively maintains task-relevant information while filtering distractions.

This dataset comprises high-density EEG recordings from 30 healthy, right-handed, native Chinese-speaking adults performing imagined and executed vocalization and writing tasks involving four Chinese strokes and four English letters. The factorial design crossed task mode, action, script and token identity, yielding 32 event-coded conditions across 15,360 task events. The dataset supports research into motor imagery, speech and handwriting-related neural communication signals.

This dataset contains intracranial EEG (iEEG) recordings from human patients, rodents, pigs, and non-human primates acquired using novel flexible, scalable, high-resolution micro-stereo-electrodes. The study evaluates the performance of these custom-fabricated depth electrodes for neural recording and includes direct electrical stimulation experiments to assess stimulation effects on brain activity. Raw and preprocessed epoched data are provided in iEEG-BIDS format with accompanying channel maps and derivatives.
