Words working together make sentences, and sentences can express meanings that are unboundedly rich. How the human brain represents the meanings of sentences has been an unsolved problem in neuroscience, but.

To measure people’s brain activation, we used fMRI (functional Magnetic Resonance Imaging). When fMRI studies were first carried out, in the early 1990s, they mostly just asked which parts of the brain “light up,” i.e.…
