Open-Access an EEG-fMRI Dataset with Carbon Wire Loops (CWLs):

 An EEG-fMRI dataset with carbon wire loops in cognitive tasks and resting state (atr-EfP-2025)

An EEG-fMRI dataset with carbon wire loops (fMRI, EEG) from ATR EEG-fMRI Project (atr-EfP-2025; supported by Innovative Science and Technology Initiative for Security [Grant Number JPJ004596], ATLA, Japan) are openly available to the scientific community for examination and exploration. We obtained from 39 participants in total during cognitive tasks (visual oddball and n-back task), and resting.

• MRI: 3T MAGNETOM Prisma fit (64-ch head coils, Siemens), 3T MAGNETOM Verio (12-ch head coils, Siemens)
• EEG: BrainAmp MR plus, BrainAmp ExG MR, BrainCap MR (63-ch EEG, 1-ch ECG, 4-ch CWLs, Brain Products)
  • Inside scanner CWL
  • Outside scanner
