The present era is the era of science's control over human beliefs. Man's need to know the nature of himself and the world around him has led him to believe in phenomena based on objective evidence, and this has caused cognitive science to become the favorite field of many scholars today. One of the main fields of cognitive sciences is linguistics, which is based on the study of language. Since language can be considered as a tool to represent the mind; therefore, cognitive linguistics goes beyond the study of the apparent structure of language and investigates very complex fundamental operations that play a major role in the development of language grammar, conceptualization, speaking and thinking. The theoretical approach of this field is based on experimental observations and scientific experiments of psychology and neuroscience, and its purpose is to understand how linguistic information is represented in the mind, to learn language and to understand and use it. In recent decades, the analysis and explanation of metaphor understanding processes has been the focus of many linguists. One of the main challenges in this direction is to find a solution that can explain the processes involved in understanding different types of metaphor. In this research, considering the mechanism of language understanding in the brain, we examined two different groups of conventional metaphors and unconventional metaphors. This research is descriptive-analytical and based on the articles, books and research done in the field of brain connection with metaphor understanding process. The results of this research show that understanding conventional metaphors causes activity in the left middle temporal gyrus, the right fusiform part and the inferior frontal gyrus. While, the fusiform part of the right side is related to the integration of visual and semantic information. On the other hand, unconventional metaphors continuously activate the left fusiform gyrus and the right precone.
