Release 7 of the HBN-EEG dataset, the EEG component of the Child Mind Institute Healthy Brain Network project, organized in BIDS format. It contains EEG recordings and behavioral responses from 381 participants aged 5-21 performing three passive tasks (resting state, surround suppression, movie watching) and three active tasks (contrast change detection, sequence learning, symbol search). Events carry HED annotations, and participants.tsv includes quality-control results and psychopathology factors derived from the CBCL questionnaire.

EEG recordings from 20 healthy participants performing a tactile detection task with confidence ratings, plus ECoG from one patient with intractable epilepsy. The data were collected to study how evidence accumulation relates to perceptual consciousness and metacognitive monitoring. Near-threshold vibrotactile stimuli were delivered to the right wrist, with detection and confidence reports collected over 500 trials per participant.

EEG dataset accompanying the PLOS ONE article 'Comprehensive methodology for sample enrichment in EEG biomarker studies for Alzheimer's risk classification' (Henao Isaza, Aguillon, Tobón Quintero, Lopera, & Ochoa Gómez, 2026). The recordings support a methodology for enriching samples in biomarker studies that classify Alzheimer's disease risk from EEG features. Data are stored in BIDS format (BrainVision .vhdr/.eeg/.vmrk files with accompanying metadata) and released under a CC0 license.

A multimodal porcine dataset of corticothalamic communication recorded during analgesia, sedation, and controlled gradual cerebral ischemia followed by recovery. It includes 11 juvenile pigs monitored across sedation states (isoflurane, fentanyl, propofol), one or two ischemia episodes, and recovery phases. Animals were divided into a sedation-only group and an ischemia group.
