About This Dataset#

LIGHT Dataset

During these guided imagery hypnotherapy sessions, a hypnotherapist integrates storytelling and deep visualizations techniques to encourage personal and wellbeing. This method allows individuals to explore and modify their subconscious narratives, in order to foster changes that resonate through their lives. This differs from traditional hypnotherapy by tapping into eudaemonic aspects of well-being, emphasizing the pursuit of meaning and self realization. 2 weeks before the first session, they will come to the lab to record baseline resting EEG (session 0).

With the exception of sessions 1, 4, and 8, all LIGHT

sessions were performed virtually. For sessions 1, 4, and 8, EEG and ECG data was collected.

The first phase of each session was guided relaxation or induction followed by prompts to visualize a perfect place of comfort and safely in ones creative imagination. Next, they were prompted to visualize a path or a set of stairs, and asked to walk down that path or stairway for ten steps, counting down from 10 to 1 outloud. They were guided to visualize and describe a chair or seat, followed by a crown.

The first phase of each session was guided relaxation or induction followed by prompts to visualize a perfect place of comfort and safely in ones creative imagination. Next, they were prompted to visualize a path or a set of stairs, and asked to walk down that path or stairway for ten steps, counting down from 10 to 1 outloud. They were guided to visualize and describe a chair or seat, followed by a crown.

After taking a seat in their imagined chair and putting on the crown, they were encouraged to pause and observe the world they had conjured. Following this brief period of reflection, awareness was drawn to a light or color that emerged from their creative mind. They identified the color of the light and were instructed to imagine that light entering and traveling through their body, filling up each cell as it passed through. The participant was instructed to leave a mental bookmark in this place so that they could come back to it at any time, before removing and storing their crown. At the end of the LIGHT sessions, the participant was asked to rise from their imagined chair or throne and count their way up from one to ten, with the session ending as the participant returned to an awake and alert state at the end of the ten count.

Baseline recordings were 5 minute of length. Hypnotherapy recordings are variable in length with multiple events indicating a hypnotherapist phase transitions.

NEMAR Processing Statistics#

The plots below are generated by NEMAR’s automated EEG pipeline. The histogram shows pipeline success for data cleaning and ICA decomposition, the percentage of data frames and EEG channels retained after artefact removal, line noise per channel (RMS, dB), and the age/gender distribution of participants.

Modality: eeg; Experiment type: Clinical/Intervention; Subject type: Healthy. Subjects: 9; recordings: 63; tasks: 5.

Parameters:
  • cache_dir (str | Path) – Directory where data are cached locally.

  • query (dict | None) – Additional MongoDB-style filters to AND with the dataset selection. Must not contain the key dataset.

  • s3_bucket (str | None) – Base S3 bucket used to locate the data.

  • **kwargs (dict) – Additional keyword arguments forwarded to EEGDashDataset.

data_dir#

Local dataset cache directory (cache_dir / dataset_id).

Type:

Path

query#

Merged query with the dataset filter applied.

Type:

dict

records#

Metadata records used to build the dataset, if pre-fetched.

Type:

list[dict] | None

Notes

Each item is a recording; recording-level metadata are available via dataset.description. query supports MongoDB-style filters on fields in ALLOWED_QUERY_FIELDS and is combined with the dataset filter. Dataset-specific caveats are not provided in the summary metadata.

__init__(cache_dir: str, query: dict | None = None, s3_bucket: str | None = None, **kwargs)[source]#
save(path: str, overwrite: bool = False, offset: int = 0)[source]#

Save datasets to files by creating one subdirectory for each dataset:

path/
    0/
        0-raw.fif | 0-epo.fif
        description.json
        raw_preproc_kwargs.json (if raws were preprocessed)
        window_kwargs.json (if this is a windowed dataset)
        window_preproc_kwargs.json  (if windows were preprocessed)
        target_name.json (if target_name is not None and dataset is raw)
    1/
        1-raw.fif | 1-epo.fif
        description.json
        raw_preproc_kwargs.json (if raws were preprocessed)
        window_kwargs.json (if this is a windowed dataset)
        window_preproc_kwargs.json  (if windows were preprocessed)
        target_name.json (if target_name is not None and dataset is raw)
Parameters:
  • path (str) –

    Directory in which subdirectories are created to store

    -raw.fif | -epo.fif and .json files to.

  • overwrite (bool) – Whether to delete old subdirectories that will be saved to in this call.

  • offset (int) – If provided, the integer is added to the id of the dataset in the concat. This is useful in the setting of very large datasets, where one dataset has to be processed and saved at a time to account for its original position.
