Tool-use skills represent a significant cognitive leap in human evolution, playing crucial role the emergence of complex technologies. Yet, neural mechanisms underlying such capabilities are still debated. Here we explore with fMRI functional brain networks involved tool-related action understanding. Participants viewed images depicting action-consistent (e.g., nail-hammer) and action-inconsistent scarf-hammer) object-tool pairs, under three conditions: semantic (recognizing tools previously seen pairs), mechanical (assessing usability control (looking at pairs without explicit tasks). During observation task-based left-brain connectivity differed within conditions. Compared to control, both conditions exhibited co-activations dorsal (precuneus) ventro-dorsal (inferior frontal gyrus) regions. However, condition recruited medial posterior temporal areas, whereas engaged inferior parietal Also, when distinguishing from an extensive frontotemporal circuit was activated. These findings support recent accounts that view understanding as combined product knowledge. Furthermore, they emphasize how left anterior lobes might be considered hubs for cross-modal integration physical conceptual knowledge, respectively.
