Neural correlates of pantomiming familiar and unfamiliar tools: Action semantics versus mechanical problem solving?

The article focuses on a study aimed at disclosing the neural correlates of planning and executing tool use pantomimes as well as examines the response of the brain to pantomiming the use of unfamiliar tools. It cites the noticeable similarity in brain activation during these pantomimes for both tools. It offers an analysis of the pattern of activation linked with the planning and execution of familiar tools compared to that of goal-directed and transitive but nontool gestures. Activation in many other frontal regions is also identified.
