Resting-state, eyes-closed scalp EEG recordings from 88 participants: 36 with Alzheimer's disease, 23 with frontotemporal dementia, and 29 healthy controls. Recordings were acquired in routine clinical conditions with a 19-electrode 10-20 montage, and cognitive status was assessed with the MMSE. The dataset includes raw recordings and preprocessed, denoised derivatives, supporting research on EEG-based dementia detection and classification.

A large EEG database from 87 healthy participants recorded during a single-day motor imagery brain-computer interface (BCI) experiment. The data are organized into three datasets (A, B, C) that share one Graz-protocol task, left- versus right-hand motor imagery, with 240 trials per participant (over 20,800 trials in total). It also provides demographic, personality and cognitive-trait information, which supports studies of how user profiles relate to BCI performance and cross-user classification algorithms.

Epoched intracranial EEG from 11 epilepsy patients (22 recordings, about 9 hours of epochs at 200 Hz) recorded during an object/scene localiser task and an associative recall task. The data are the extra-hippocampal channels released by Treder et al. (2021) on OSF and repackaged into BIDS iEEG format. The original study examined the role of the hippocampus as a switchboard between perception and memory.

EEG recordings from a visual working memory task in healthy controls and individuals with sub-acute mild traumatic brain injury (mTBI), with mind wandering probes inserted between trials. Participants were tested across up to three sessions, from 3-14 days post-injury to roughly 4 months later, with MRI acquired only in the first session. Data were collected in 2016-2018 and have not been published in a dedicated paper.

The Multimodal Resource for Studying Information Processing in the Developing Brain (MIPDB) contains high-density EEG and eye-tracking recordings from 111 participants in a developmental cohort spanning childhood to adulthood. Participants completed a battery of cognitive and perceptual paradigms: resting state, surround suppression, naturalistic viewing, contrast change detection, sequence learning, and symbol search. The resource supports research on the maturation of information processing in the human brain. This BIDS conversion publishes each recording block as a separate task.
