Magnetic resonance imaging (MRI) is being widely used both as a diagnostic tool and a research method. With the advancement and easy use of various MRI methods, researchers have started to use different approaches to neuroscience research. In this context, connectivity has become one of the most used methods for brain imaging in research, clinical and surgical fields. Resting state functional magnetic resonance imaging, diffusion tensor imaging and tractography stand out among different connectivity methods involving MRI. With these applications, not only structural connections between different brain areas, but also functional connections can be shown and evaluated. Similar to other new methods, there are several advantages and disadvantages of these methods, as well as limited usage in clinics. However, with the increasing simplicity and attainability, connectivity methods can be conventionalized and clinical applicability can be provided.
