EEG recordings for semantic decoding of imagined animals and tools during auditory imagery task

EEG Zarr

This dataset contains EEG recordings from 7 participants performing an auditory imagery task, in which they imagined the sounds made by objects from the semantic categories of animals and tools for 5 seconds. It supports research on semantic decoding and brain-computer interfacing. Recordings were made with a 64-channel BioSemi system, with additional EOG, physiological, and respiration channels.

Cognitive Electrophysiology in Socioeconomic Context in Adulthood: An EEG dataset

EEG Zarr

This dataset contains EEG recordings from 127 young adults (18-30 years) together with retrospective indicators of childhood family socioeconomic status (SES) and adult SES measures, including education, income, food security, and home and neighborhood characteristics. EEG was recorded during ERP CORE tasks or adaptations of them, which target perception, cognition, and action. The dataset also includes an adult ADHD symptoms checklist, so that links between SES, ADHD symptoms, and neural activity can be examined in a socioeconomically diverse sample.

Collaborative rule learning promotes interbrain information alignment

EEG Zarr

This dataset contains EEG recordings from 24 pairs of participants performing a 4-way categorisation task based on rules they first agreed upon together. Participants also completed pre- and post-tests on the same stimuli. The data were collected to investigate how collaborative rule learning promotes information alignment between interacting brains.

The role of REM sleep in neural differentiation of memories in the hippocampus

ANAT EEG FMAP FUNC Zarr

This dataset contains fMRI and EEG recordings from 69 participants examining the role of rapid eye movement (REM) sleep in the neural differentiation of memories in the hippocampus. Each participant completed three fMRI scans and one EEG session, which contained either nap sleep data or quiet wake data depending on the participant's condition.

ERC_CoG PROMENADE - WP2 - MetaImagery (Metaphor and Mental Imagery)

EEG Zarr

EEG and behavioral dataset from 39 Italian-speaking university students performing a picture-matching task in which target pictures matched or mismatched a preceding cue. Cues were physical (picture), imagery (single word), literal sentence, or metaphorical sentence. The data are provided as preprocessed long epochs (filtered, mastoid re-referenced, ocular ICA cleaned). The dataset was collected within the ERC PROMENADE project to test how mental representations generated by different cue types influence target picture processing. Vocabulary and mental imagery measures are included per participant.

Cognitive Electrophysiology in Socioeconomic Context in Adulthood

EEG Zarr

EEG recordings from 127 young adults (18-30 years) collected alongside retrospective objective and subjective measures of childhood family socioeconomic status (SES) and adult SES indicators, including educational attainment, income, food security, and home and neighborhood characteristics. Tasks were taken or adapted from the ERP CORE compendium to capture perception, cognition, and action-related neural activity. The dataset also includes an ADHD-related symptoms checklist, allowing analyses of links between SES, ADHD symptoms, and brain electrophysiology.
