Brain scans illustrate the second, more powerful, use of metaphor. When participants in one study read the words ‘he had a rough day’, their neural regions involved in feeling textures became more activated, compared with those who read ‘he had a bad day’. In another, those who read ‘she shouldered the burden’ had neural regions associated with bodily movement activated more than when they read ‘she carried the burden’. This is prose writing that deploys the weapons of poetry. It works because it activates extra neural models that give the language additional meaning and sensation.
