Simultaneous EEG and fMRI signals during sleep from humans

ANAT EEG FUNC Zarr

This dataset contains simultaneous EEG and BOLD fMRI recordings from 33 healthy participants scanned at Penn State, including resting-state and sleep sessions. EEG was acquired with a 32-channel MR-compatible system, and the data are accompanied by sleep stage scores for each 30-second epoch. It supports investigation of autonomic and neural events during transient arousal changes across sleep.

Medial and lateral orbitofrontal cortex in approach-avoidance decisions (Starkweather et al., 2026): SEEG high-frequency activity, 6 patients (derivative)

iEEG

Derivative stereo-EEG dataset of high-frequency activity (HFA, 70-150 Hz) recorded from six patients with depth electrodes performing an approach-avoidance decision task. It supports analysis of the differential contributions of medial and lateral orbitofrontal cortex to decision-making under conflict. The data are the authors' processed HFA, epoched per trial and aligned to trial onset and decision, and are accompanied by per-trial behavioural data and artifact-review labels.

SRM Resting-state EEG

EEG Zarr

This dataset contains four-minute eyes-closed resting-state EEG recordings extracted from the Stimulus-Selective Response Modulation (SRM) project paradigm at the University of Oslo. It includes 64-channel BioSemi recordings from 111 healthy control participants at a first session (t1), with a subset re-recorded at a later session (t2). Raw data are provided with a fully automated cleaned derivative, along with demographic and cognitive test scores.

Alpha power indexes working memory load for durations

ANAT MEG Zarr

Raw magnetoencephalography (MEG) recordings from 23 healthy adults performing an n-item delayed temporal reproduction task. Participants held sequences of one or three empty auditory intervals in memory and then reproduced them by button press. The dataset also includes EOG, ECG, digitized head and electrode positions, a two-minute eyes-open resting-state recording, and individual anatomical MRI. It supports research on working memory dynamics, auditory processing, motor responses and resting activity.
