The Siena EEG Dataset.

The database consists of EEG recordings of 14 patients acquired at the Unit of Neurology and Neurophysiology of the University of Siena.

Subjects include 9 males (ages 25-71) and 5 females (ages 20-58). Subjects were monitored with a Video-EEG with a sampling rate of 512 Hz, with electrodes arranged on the basis of the international 10-20 System.

Most of the recordings also contain 1 or 2 EKG signals. The diagnosis of epilepsy and the classification of seizures according to the criteria of the International League Against Epilepsy were performed by an expert clinician after a careful review of the clinical and electrophysiological data of each patient.

This BIDS-compatible version of the dataset was published by Jonathan Dan [Dan2025] and is based on the original Siena Scalp EEG Database [Detti2020a], [Detti2020b].

Added in version 1.3.

Parameters:

  • root (pathlib.Path | str) – The root of the BIDS path.

  • subjects (str | array-like of str | None) – The subject ID. Corresponds to “sub”.

  • sessions (str | array-like of str | None) – The acquisition session. Corresponds to “ses”.

  • tasks (str | array-like of str | None) – The experimental task. Corresponds to “task”.

  • acquisitions (str | array-like of str | None) – The acquisition parameters. Corresponds to “acq”.

  • runs (str | array-like of str | None) – The run number. Corresponds to “run”.

  • processings (str | array-like of str | None) – The processing label. Corresponds to “proc”.

  • recordings (str | array-like of str | None) – The recording name. Corresponds to “rec”.

  • spaces (str | array-like of str | None) – The coordinate space for anatomical and sensor location files (e.g., *_electrodes.tsv, *_markers.mrk). Corresponds to “space”. Note that valid values for space must come from a list of BIDS keywords as described in the BIDS specification.

  • splits (str | array-like of str | None) – The split of the continuous recording file for .fif data. Corresponds to “split”.

  • descriptions (str | array-like of str | None) – This corresponds to the BIDS entity desc. It is used to provide additional information for derivative data, e.g., preprocessed data may be assigned description='cleaned'.

  • suffixes (str | array-like of str | None) – The filename suffix. This is the entity after the last _ before the extension. E.g., 'channels'. The following filename suffix’s are accepted: ‘meg’, ‘markers’, ‘eeg’, ‘ieeg’, ‘T1w’, ‘participants’, ‘scans’, ‘electrodes’, ‘coordsystem’, ‘channels’, ‘events’, ‘headshape’, ‘digitizer’, ‘beh’, ‘physio’, ‘stim’

  • extensions (str | array-like of str | None) – The extension of the filename. E.g., '.json'. By default, uses the ones accepted by mne_bids.read_raw_bids().

  • datatypes (str | array-like of str | None) – The BIDS data type, e.g., 'anat', 'func', 'eeg', 'meg', 'ieeg'.

  • check (bool) – If True, only returns paths that conform to BIDS. If False (default), the .check attribute of the returned mne_bids.BIDSPath object will be set to True for paths that do conform to BIDS, and to False for those that don’t.

  • preload (bool) – If True, preload the data. Defaults to False.

  • n_jobs (int) – Number of jobs to run in parallel. Defaults to 1.
