Thoughts con­sist of more than words

Science Illustrated - - HUMANS/ THE BRAIN -

When we think about fa­mil­iar ob­jects such as a ham­mer, the thought does not only cause ac­tiv­ity in the lan­guage cen­tres of the brain. It produces a spe­cific ac­tiv­ity pat­tern in sev­eral brain re­gions, which process ac­tions related to the ob­ject. The word ham­mer dis­charges neu­rons in the frontal lobes, which have to do with mo­tor func­tions, as the word makes us think about how to hold a ham­mer, etc. By de­cod­ing the pat­tern, sci­en­tists can read our minds.
