One of the grand challenges in neuroscience is to understand the developing brain ‘in action and in context’ in complex natural settings. To address this challenge, it is imperative to acquire brain data from freely-behaving children to assay the variability and individuality of neural patterns across gender and age.
Recent advances in scalp electroencephalography (EEG) as a neuroimaging tool have now allowed researchers to overcome technical challenges and movement restrictions typical in traditional neuroimaging studies. Fortunately, recent mobile EEG devices have enabled studies involving cognition and motor control in natural environments that require mobility, such as during art perception and production in a museum setting, and during locomotion tasks.

b) AML470 dataset, closed loop:
Instructions for accessing files:
1) Here are the details of the naming convention used in the filenames of the datasets used to generate figure 2, 3, S3.
Let us use the folder name “20210614_RunHeadandTailRailswithDelays_AML470_0-20-40-60-80intensity” as an example. The different components of the names are:
a) Date: In the above example, this dataset was collected on 20210614 (YYYYMMDD).
b) Experiment type: "RunHeadandTailRailswithDelays" represents the data collected by stimulating head, tail, or both.
c) Name of the strain: The above example shows the dataset collected from "AML470" strain.
d) Experiment specific information: The tag “0-20-40-60-80intensity” says that 0, 20, 40, 60, and 80uW intensity was used during this dataset.
Moreover, once you go inside each folder, you will see many subfolders with the date and time stamp. For e.g. a subfolder in the above folder is Data20210614_141921_BoxA-PC which basically says the time stamp at which this dataset was recorded (DataYYYYMMDD_HHMMSS) followed by the name of the experimental box (BoxA-PC or BoxB-PC or BoxC-PC or BoxD-PC).
2) Here are the details of the naming convention used in the filenames of the datasets used to generate figure 4 and table 1.
Let us use the folder name “20210624_RunRailsTriggeredByTurning_Sandeep_AML67_10ulRet_red” as an example. The different components of the names are:
a) Date: In the above example, this dataset was collected on 20210624 (YYYYMMDD).
b) Experiment type: "RunRailsTriggeredByTurning" represents the data collected in closed loop protocol whereas "RunFullWormRails" represents the data collected in open loop protocol. Thus, the above example represents a dataset collected using closed loop protocol.
c) Name of the user: In the above example, the user is "Sandeep".
d) Name of the strain: The above example shows the dataset collected from "AML67" strain. Folders containing the datasets collected from AML470 will say "AKS_483.7.e_mec4_Chrimson".
e) ATR information: All the datsets used retinal on the OP50 plates to grow the worms, and hence have the tag "10ulRet".
f) Color of the stim: "red" tag says that in this protocol red stimulus was delivered to the worms.
Moreover, once you go inside each folder, you will see many subfolders with the date and time stamp. For e.g. a subfolder in the above folder is Data20210624_105852 which basically says the time stamp at which this dataset was recorded (DataYYYYMMDD_HHMMSS).
Details of files inside each experimental folder:
The dataset is in the form of the output of the real-time LabVIEW instrument for maximum compression. It still needs to go through post-processing before further analysis.
Post-processing can be done by running the /ProcessDateDirectory.m MATLAB script from the code repository.
It is organized into date directories, which aggregate all the experiments collected on the same day.
Each experiment is it's own time stamped folder within a date directory, and it contains the following files:
- camera_distortion.png contains camera spatial calibration information in the image metadata
- CameraFrames.mkv is the raw camera images compressed with H.265
- labview_parameters.csv is the settings used by the instrument in the real-time study
- labview_tracks.mat contains the real-time tracking data in a MATLAB readable HDF5 format
- projector_to_camera_distortion.png contains the spatial calibration information that maps projector pixel space into camera pixel space
- tags.txt contains tagged information for the experiment and is used to organize and select experiments for analysis
- timestamps.mat contains timing information saved during the real-time experiments, including closed-loop lag.
- ConvertedProjectorFrames folder contains png compressed stimulus images converted to the camera's frame of reference.
The given Dataset is record of different group people either healthy subjects or subclinical cardiovascular disease(CVD) with history coronary heart disease or hypertension for superficial body features, original photoplethysmography imaging(iPPG) signal and characteristics.
The main purpose of the dataset is to understand the relationship between CVD and high-dimensional ippg characteristics.
Recent advances in computational power availibility and cloud computing has prompted extensive research in epileptic seizure detection and prediction. EEG (electroencephalogram) datasets from ‘Dept. of Epileptology, Univ. of Bonn’ and ‘CHB-MIT Scalp EEG Database’ are publically available datasets which are the most sought after amongst researchers. Bonn dataset is very small compared to CHB-MIT. But still researchers prefer Bonn as it is in simple '.txt' format. The dataset being published here is a preprocessed form of CHB-MIT. The dataset is available in '.csv' format.
- The tool used for preprocessing is Anaconda-Jupyter Notebook on Intel 8th gen i5 processor with 8GB RAM
- The dataset is prepared by extracting datapoints from '.edf' by using mne package in python. Equal amount of preictal and ictal data are extracted.
- A period of 4096 seconds (68 minutes) each of preictal and ictal data is extracted from the '.edf' files. All ictal periods for 24 patients annotated have been included in the dataset.
- Datapoints are loaded and preprocessed as dataframes by using pandas package in python.
- System RAM size should be available to the maximum possible extent as dataframes are large.
- The file chbmit_preprocessed_data.csv can be used as is for machine learning and deep learning models.

The MAUS dataset focused on collecting easy-acquired physiological signals under different mental demand conditions. We used the N-back task to stimuli different mental workload statuses. This dataset can help in developing a mental workload assessment system based on wearable device, especially for that PPG-based system. MAUS dataset provides ECG, Fingertip-PPG, Wrist-PPG, and GSR signal. User can make their own comparison between Fingertip-PPG and Wrist-PPG. Some study can be carried out in this dataset
The database is organized in 2 folders and documentation:
• Data – raw signal recordings for the individual participants, including extracted Inter-Beat-Interval sequence and participants’ respond in N-back task
• Subjective_rating – subjective rating of sleep quality and NASA-TLX
• MAUS_Documentation.pdf – documentation of dataset description and details.
The data set is collected using Neurosky MindWave 2.0 Headset. It uses a single dry electrode placed at FP-1 position for the acquisition of EEG signals. The data is collected from Healthy Individuals and Epileptic Patients performing different Activities of Daily Living (ADLs) in an unconstraint environment.
The data files are stored in a comma-separated value (.csv) format.
60 sample files of activities performed by healthy individuals and 30 sample files of activities performed by epileptic patients are present in two separate folders in the .zip file.
The sampling frequency of the headset is 512Hz and each activity is performed for a duration of 20 seconds. Every data file contains raw EEG data in a single column.
