Bruera's research investigates how the human brain processes fine-grained meaning variations in language, particularly verb-noun semantic composition. They utilize functional MRI (fMRI) and computational models like itGPT-2 to predict neural activity patterns associated with concreteness in context. Their studies compare contextualized language models with human concreteness ratings to understand semantic composition mechanisms in brain regions such as the left posterior superior temporal sulcus (pSTS), inferior frontal gyrus (IFG), and anterior temporal lobe (ATL).

Their recent work demonstrates that contextualized language models outperform simpler composition approaches in predicting brain activity during semantic processing. Key findings highlight the role of the language network and motor areas in holistic semantic composition, integrating linguistic and sensorimotor representations.
