Objectives: The human brain is one of the most complicated biological structure in the entire universe. It is incredibly challenging to see how it functions, mainly during scatter-brain, and when diseases occur in human beings. The notable contribution from consultants, academic institutions, researchers, and others have contributed significant findings in the field of neuroscience and made substantial changes in different dimensions. The exploration of the brain is becoming an emerging area due to the rapid advancement of neuroimaging techniques.
Methods: Brain disorder is one such significant disease that is very difficult to diagnose, notably, which influence many people worldwide.
Results: In this review, we explore various tools and software to construc and analyze brain networks and different brain scanning methods. Further, this study addresses the research work related to brain networks, including various graph theory methods. More specifically, we present the different diagnostics techniques in brain disorders.
Conclusion: This review provides a detailed understanding of brain scans, tools, and brain network construction methods. Lastly, applications of complex network theory will contribute new insights about brain structure and function.
