According to the theory of embodied cognition, developed by Lakoff, the body, when interacting with its environment, has a significant effect on the way metaphors are formed in the body. 'origin. Gallese and Lakoff (2005) argue that “conceptual knowledge is embodied, that is, it is mapped within our sensorimotor system” (p. 456). Their arguments were based on findings that imagination and action use a shared neural substrate, which led them to argue that understanding also has roots in the neural substrate. They developed an interactionist theory based on the embodiment of understanding, in the sense that understanding is “structured by our constant encounter and interaction with the world through our bodies and brains” (Gallese and Lakoff, 2005, p. 456). To the extent that brain circuits link modalities, “infusing each with the properties of the others” (Gallese and Lakoff, 2005, p. 456), the sensorimotor system simply exploits the pre-existing condition of the sensorimotor system for the formation of metaphors. Lakoff (1987) defined all metaphors as conceptual metaphors, "where part of the structure of a more concrete concept...
