Functional neuroimaging techniques help us understand how the brain works, but they also come with some big challenges. Here are the main problems:

1. Resolution Limitations:

   • Techniques like fMRI can’t catch fast brain activity very well. This means it's hard to see what happens in the brain in real-time.

2. Interpretation Ambiguity:

   • Just because two things happen together doesn’t mean one causes the other. We can’t directly figure out someone’s thoughts or feelings just from these images.

3. Variability Across Individuals:

   • Different people show brain issues in unique ways, which makes it hard to come up with rules that work for everyone.

To solve these problems, future studies should use a mix of different methods. Combining neuroimaging with techniques that measure electrical activity in the brain could give us a better picture of what’s happening.

Also, new technology, like machine learning, can help us make sense of the data we collect. This could lead to better understanding of brain diseases and how the nervous system works.
