Magnetic Resonance Imaging (MRI) and functional MRI (fMRI) are important tools for studying the brain. However, they come with some challenges.

1. Challenges of MRI and fMRI:

   • Cost and Accessibility: MRI machines are expensive. This makes it hard for some hospitals to have them, especially in places with fewer resources.
   • Patient Movement: If a patient moves even a little during the scan, it can make the images unclear. This makes it harder for doctors to read the results.
   • Speed of Measurement: fMRI is not as fast as other methods, like checking brain waves. This means it can miss quick changes in brain activity.

2. Possible Solutions:

   • New Technology: Making MRI machines cheaper and easier to carry could help more places get them.
   • Better Software: Creating improved programs can help fix problems caused by patient movement during scans.
   • Mixing Methods: Using fMRI along with other tests, like EEG, might give a clearer picture of brain activity and help researchers understand how the brain works better.

These ideas could help solve some of the challenges that come with using MRI and fMRI in brain studies.
