Abstract: The main aim of this work was to conduct a systematic review of the scientific contributions to understanding the psychophysiological mechanisms related to tool use in non-human primates. Results showed that the tool use is observed in several species of non-human primates, which use tools to obtain food, even sequentially. In macaque and human species, it has been observed prefronto-parietal circuit activation. The intrinsic properties of this circuit are linked to the tool use in primates. Specific activation in the parietal lobe observed in humans could be a recent evolutionary feature in the primate order.
