We often assume language is a purely abstract mental exercise, but research into the neural grounding of semantics tells a different story. The tension lies in whether thought is truly separate from the physical actions we perform every day.

The lecture challenges the a-modal view of cognition by demonstrating that processing words systematically recruits the brain's motor and premotor cortex. Instead of localized modules, semantic meaning is served by distributed interactive networks.

• The brain dedicates specific neural areas to different body parts in a somatotopic arrangement.
• Linguistic comprehension involves a partial reactivation of neural substrates used for mental imagery and physical movement.
• Evidence like the ACE effect shows that language with implied direction facilitates physical responses.
• A ...
