# Simultaneous cortico-spinal fMRI (CoSpine) Motor-dataset
**Version:** v1.0.0
**Date:** 2025-06-30
**BIDS-compliant**
---
## 1. Dataset Overview
This is the first open-access, BIDS-compliant cortico-spinal task-based fMRI dataset using **voluntary motor tasks**. It enables exploration of cortico-spinal dynamics during repetitive hand movements by providing simultaneous brain-and-spinal fMRI, physiological recordings, and task structure.
- **Task:** Voluntary hand grasping (left and right)
- **Modalities:** fMRI (task-motor BOLD), structural MRI (T1w), EPI-based field maps (reverse phase encoding), physiological signals (pulse & respiration), events/behavioural logs
- **Subjects:** 22 healthy participants
---
## 2. Experimental Design
- **Task:** Participants performed hand grasping using a **6.5 cm diameter dynamometer**.
- **Cueing:** Auditory cues presented via MRI-compatible headphones.
- **Design:** 12 blocks in total (6 for each hand). Each block consisted of **8 grasps at 1 Hz**.
- **ITI:** Randomized between **16–20 seconds**.
- **Software:** Stimuli were presented and synchronized using **E-Prime 2.0** on Windows.
Event timings (onset, duration) and trial types (motorL, motorR) are documented in each `*_events.tsv`.
---
## 3. Data Acquisition
- **Scanner:** 3T Siemens Prisma (Erlangen, Germany)
- **Head coil:** Standard 64-channel head-neck coil
- **fMRI protocol:** Simultaneous acquisition of brain and spinal cord
- **Physiology:** Pulse and respiration recorded during all task runs

## 5 Quality control / preprocessing
- Structural T1-weighted images have been defaced for privacy.
- Preprocessed data is placed in `derivatives/preprocessed/`.
