NIBS-BIDS (BEP037)

The NIBS-BIDS repository contains supporting files for the NIBS-BIDS extension proposal.

Mock experiments for NIBS-BIDS examples

Below are some basic TMS experiments to test the current NIBS-BIDS framework. Outcome data files are described which should be converted into BIDS format for a single participant (sub001). Hardware and pulse shape are dealers choice.

1. Online motor TMS-EMG experiment

TMS applied during EMG recording. No neuronavigation.

• Resting motor threshold (no recorded data)
• Active motor threshold (no recorded data)
• Intensity required for MEP of 1 mV (no recorded data)
• Single pulse MEPs (input-output curve) - 10 trials at 90%, 100%, 110% and 120% RMT, interleaved
• SICI (2 ms ISI) - 10 trials single pulse, 10 trials paired pulse, interleaved. Conditioning pulse = 80% AMT, Test pulse = S1mV.

2. Online prefrontal TMS-EEG experiment

TMS applied to prefrontal cortex during EEG recording. Coil position recorded using neuronavigation with each trial.

• Resting motor threshold (no recorded data)
• Single pulse TEPs (120% RMT) - 100 trials

3. Offline prefrontal iTBS experiment

iTBS applied to prefrontal cortex. Working memory performance (no neural recordings) assessed before and after stimulation. Coil position recorded using neuronavigation.

• Resting motor threshold (no recorded data)
• Pre working memory task (beh file)
• iTBS (70% RMT, 600 pulses, standard parameters)
• Post working memory task (beh file)

4. (TMS-BIDS team): Multimodal TMS Experiment During Product Preference Decision-Making

In this neuro-marketing study, participants evaluate product preferences (Brand A vs Brand B) while undergoing brain stimulation. During the decision-making task, the following data are collected simultaneously:

• EEG (to monitor cognitive responses),
• fNIRS (to track prefrontal cortex activation),
• Behavioral data — including response times and button presses,
• TMS is applied to the dorsolateral prefrontal cortex (dlPFC) during evaluation phases to modulate decision-related activity.

• Protocol: Single-pulse TMS
• Target: dlPFC
• Intensity: 110% of RMT
• Total Pulses: 60 (10 pulses per block, 6 blocks total)
• Neuronavigation: Yes, coil position recorded for each pulse

5. (TMS-BIDS team): Combined TMS Motor Study — Mixed Online/Offline Stimulation

This example demonstrates a realistic multi-session experiment combining both offline and online transcranial magnetic stimulation (TMS) protocols targeting the motor cortex and parietal regions.

• Session 1 (Offline): Continuous Theta Burst Stimulation (cTBS) applied to the parietal cortex (600 pulses, no concurrent recording).

• Session 2 (Online): Mixed TMS protocols including Single Pulse, Short-Interval Intracortical Inhibition (SICI), Intracortical Facilitation (ICF), and Silent Period (SP) — applied during EMG/EEG recording over the motor cortex.

• Session 3 (Online): Repetition of session 2 to assess test–retest reliability.
