The folder is organized into files detailing the experiment setup (under “MeMoSoft layout” and “Experiment”) and the raw recordings (under “Raw data”).

• Experiment Configuration and Layout (MeMoSoft layout, Experiment): These files specify the technical and spatial details of the recording setup for a general participant.
  
  • Acquisition Layout (p1_acq_layout.jmms, digpts.txt, p1_3D_data.csv): Contains the 3D coordinates for all sensors and cranial landmarks (Nz, Iz, LPA, RPA), along with head distances (e.g., circumference 55.0 cm). It defines EEG channels and NIRS channels (LED-Detector pairs) with their exact inter-optode distances (e.g., LED2_DET2 at 2.0 cm, LED14_DET4 at 9.1 cm).
  • Sensor Maps (p1_sensorsLandmarks_img.png, Go_NoGo_NIRS_EEG_Simplified_Layout.png): Visual representations of the sensor placements, mapped to cortical areas such as the Frontal, Motor, Sensory, Somatosensory, and Visual areas, often using the International 10-20 EEG system nomenclature.
  • Task Design (Experimment_design.png): Outlines the “Go/NoGo Task” structure, which includes a baseline period, instruction, and two primary task blocks (Go and NoGo). Stimuli are presented for 800 ms with a 200 ms inter-stimulus interval.
• Raw Data Sessions (Raw data/MedelOpt+, Raw data/BrainBody): This section contains the time-series data captured from the sensors during two separate recordings – (1) MedelOpt+ only with EEG and fNIRS; and (2) MedelOpt+ with fNIRS only & MP160 and BioNomadix modules for physiology (PPG, EDA, REPS, ECG and ACC).
