Identify a neuroimaging technique that can be used to study brain activity during movement tasks.

Functional MRI (fMRI) is a valuable neuroimaging technique particularly suited for studying brain activity during movement tasks. This imaging method measures brain activity by detecting changes in blood flow; specifically, it takes advantage of the fact that active brain regions require more oxygen and thus show increased blood flow. By comparing the fMRI signals from different task conditions, researchers can identify which areas of the brain are engaged in specific movement tasks, making it a powerful tool in understanding the neural mechanisms underlying motor control and coordination.

The utilization of fMRI in movement analysis allows for high spatial resolution, meaning that distinct brain regions can be closely examined, and it provides insights into brain function in real-time. This makes it particularly relevant in fields like stroke rehabilitation, where understanding the activation patterns in response to rehabilitation tasks can inform therapeutic strategies.
