Confounding Variables: Factors that are not being studied but can impact the results, making it difficult to determine if the observed effects are solely due to brain function or other factors.
Expensive Equipment: MRI scans require expensive equipment and maintenance costs, which may limit access for researchers with limited resources.
Inability to Measure Real-time Activity: MRI scans provide static images and cannot accurately capture real-time brain activity, limiting our understanding of dynamic processes happening in the brain.
