Abstract:
When using novel tools with low semantic content, the left inferior-frontal-gyrus (IFG) plays a role. We argue that this activation is not purely specific to novel tool use but rather represents part of a cross-domain cognitive network supporting sequential planning processes. The IFG does not only manage information flow between distributed areas but functionally contributes by maintaining focus on the intended target state and supporting the processing, monitoring, and adjustment of steps needed to achieve that goal. These cognitive functions are particularly important when compensation for reduced tool-related semantic knowledge is needed during the usage of novel tools and technologies.

Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
