Imaging techniques are really important for understanding how our brain connects and works. These techniques help us see the complex network of connections in our brains.

Types of Imaging Techniques:
- Magnetic Resonance Imaging (MRI): This method gives detailed pictures of the brain. It helps us see different areas of the brain clearly.
- Diffusion Tensor Imaging (DTI): This is a special kind of MRI. It tracks how water moves in the brain's white matter. This helps us understand how different parts of the brain are connected. Studies show that DTI can find changes in these connections very accurately, down to just 1 millimeter.
- Functional MRI (fMRI): This type of scan shows how active the brain is by measuring changes in blood flow. It can uncover how different brain areas work together, with a detail level of about 3 millimeters.

Interesting Facts:
- A big study has found that there are about 86 billion neurons in the human brain!
- The Human Connectome Project has identified around 200 different areas in the part of the brain called the cerebral cortex. This shows just how complex connections in the brain can be.

Why This Matters:
- These imaging techniques help doctors diagnose brain disorders better. By mapping how brain connections change, they can learn more about conditions like schizophrenia. Research shows that in 20-30% of patients with this condition, their brain activity patterns are different compared to healthy people.
Overall, imaging techniques are helping us understand the brain’s structure and how it functions, which is vital for treating brain-related illnesses.
