This study reexamines conceptual metaphor theory from a neuroscientific perspective. It argues that metaphor is not just a linguistic device, but the basic way the human mind works through the interaction between the brain, body, and culture. Previous research in cognitive linguistics has shown that people understand abstract ideas through physical and sensory experiences. However, less research has explained how these metaphorical mappings are realized in the brain. To address this gap, this study reviews findings from fMRI, EEG, ERP, and MEG studies on metaphor processing. The results show that understanding metaphors involves not only traditional language areas, such as Broca’s and Wernicke’s areas, but also wider brain networks, including prefrontal, temporal, parietal, and occipital regions, as well as emotion-related structures like the amygdala. Recent studies further suggest that metaphor comprehension unfolds in stages, requiring extra effort to adjust and combine meanings, as seen in the N400 and P600 responses. In conclusion, these findings support an embodied, network-based view of metaphor and highlight the importance of linking cognitive linguistics with neuroscience.
