This dataset contains raw MEG and EEG recordings from a study investigating how the brain represents object space dimensions through temporal dynamics analysis. The main folder contains raw MEG data for all participants in BIDS format. The sourcedata folder contains raw EEG data in BDF format along with concurrent behavioral trial data documenting stimulus presentation and trial structure. Participants performed a visual task while neural activity was recorded from both modalities.

A color change detection task dataset organized in BIDS format containing intracranial electrophysiological (iEEG) recordings from participants performing a visual perception task. Participants were required to detect color changes in visual stimuli while neural activity was recorded from implanted electrodes. The dataset includes raw iEEG data, electrode localization information, and task event markers, organized according to the iEEG-BIDS specification. This standardized format facilitates reproducible analysis and sharing of human intracranial brain imaging data. For complete attribution and dataset documentation, please refer to the dataset files and associated publications.

This dataset contains electroencephalography (EEG) recordings from a repeated awakening study investigating the effects of propofol sedation on dreaming and the utility of complexity measures in capturing consciousness dynamics. Participants underwent multiple sedation-awakening cycles with EEG recordings during wakefulness (eyes open and closed), sedation, and transcranial magnetic stimulation sessions. The study aims to elucidate the relationship between EEG complexity measures and subjective dream experiences during pharmacological sedation.

This dataset contains electroencephalographic (EEG) recordings from 23 participants performing a passive viewing task involving visual scenes with occluded and uncovered game pieces. Participants viewed scenes with varying numbers of visible and hidden objects to investigate neural responses to object numerosity under occlusion conditions. The study employed a factorial design with 640 trials across eight blocks, systematically manipulating the number of initially visible pieces (4 or 32) and uncovered pieces (0-32) to examine how the brain processes object quantity in partially occluded visual scenes.

The Podcast ECoG dataset provides intracranial electrophysiological recordings from 9 participants with 1,330 electrodes during natural story listening. This dataset combines high spatiotemporal resolution human electrocorticography with a naturalistic language comprehension paradigm, including raw and preprocessed high-gamma data, auditory stimuli, word-level transcripts, and linguistic features from acoustic properties to large language model embeddings. The resource includes tutorials and serves as both a pedagogical tool and foundation for investigating neural mechanisms of narrative comprehension.

This event-related potential (ERP) study investigates neural mechanisms underlying the integration of fingerspelling, printed English words, and American Sign Language (ASL) signs in deaf readers. Using a priming paradigm with 300 prime-target pairs, the dataset captures electrophysiological responses to identity and translation primes across three modalities, providing insights into cross-modal language processing in the deaf population.

This dataset contains intracranial electrophysiology recordings and behavioral data from a categorized free recall task with real-time closed-loop brain stimulation during encoding. Participants studied semantically organized word lists, performed distractor tasks, and freely recalled items while a machine learning classifier trained on prior sessions predicted subsequent memory performance and triggered stimulation for low-confidence encoding events. The study demonstrates the application of predictive neural decoding to modulate memory encoding through targeted electrical stimulation.

This dataset contains intracranial electrophysiology recordings and behavioral data from a delayed free recall task with real-time closed-loop brain stimulation during encoding. Participants studied word lists, performed distractor arithmetic tasks, and freely recalled words while an L2 logistic regression classifier trained on encoding neural features guided stimulation delivery to optimize memory performance. Data were collected across multiple clinical sites as part of a collaborative memory research initiative.
