About This Dataset#
The dataset consists of data from two experiments in which subjects were presented bursts of noise from loudspeakers at different elevations. Subjects who participated in either experiment were initially tested in their ability to localize elevated sound sources. Both experiments were conducted in a hemi-anechoic chamber.
Localization Tests
Bursts of pink noise were presented from loudspeakers at different elevations and 10° azimuth (to the listeners right). In the localization test preceding experiment I, these loudspeakers were positioned at elevations of +50°, +25°, 0° and -25° while the localization test preceding experiment II also included a loudspeaker at -50° elevation. Localization test data is missing for sub-001, sub-002 and sub-003
Overview
Deviant Detection (Experiment 1)
Subjects 001-023 participated in this experiment. Subjects heard a long trail of noise from one loudspeaker (adapter), followed by a short burst of noise from another loudspeaker (probe). The elevation of the adapter and probe are encoded in the event values: 2: adapter at 37.5°, probe at 12.5° 3: adapter at 37.5°, probe at -12.5° 4: adapter at 37.5°, probe at -37.5° 5: adapter at -37.5°, probe at 37.5° 6: adapter at -37.5°, probe at 12.5° 7: adapter at -37.5°, probe at -12.5° 8: no adapter, any non-target location (deviant) The behavioral data contains the trial numbers where a deviant was presented and weather the subject responded within one second by pressing a button.
One-Back (Experiment II)
Subjects 100-134 participated in this experiment. Subjects heard a long trail of white noise through open headphones followed by a short burst of noise from one of the loudspeakers. The loudspeaker’s elevation is encoded in the event values: 1: 37.5°, 2: 12.5°, 3:-23.5°, 4:-37.5° Roughly five percent of trials were targets where subjects heard a beep after the trial, prompting them to localize the previously heard sound. The number of those target trials, as well as the target’s elevation and the subject’s response can be found in thee behavioral data. A subset (sub-130-134) participated in a second session of the experiment. This session was identical to the first task with the difference that the subjects had molds inserted that disrupted their ability to perceive sound elevation.

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.

Examples
>>> from eegdash.dataset import DS005131 >>> dataset = DS005131(cache_dir="./data") >>> recording = dataset[0] >>> raw = recording.load()
- __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.
