NeuroCognitive Bases of Tool Use
Sponsor: Hospices Civils de Lyon
Summary
Tool use is considered to be the hallmark of complex cognitive adaptations that humans have achieved trough evolution, that provides an adaptive advantage to the human species. Even if nonhuman species do use tools too, human tool use is much more complex and sophisticated. If humans have special abilities for tool use, it has to be grounded in a specific neuroanatomical substrate. Humans and nonhumans share a similar prehension system located within the superior parietal lobe and the intraparietal sulcus. However, there is a human specificity: the supramarginal gyrus within the left inferior parietal lobe is unique to humans, and could play a central role in tool use. This project aims to study the neurocognitive bases of human tool use with functional Magnetic Resonance Imaging (fMRI), to precise the cognitive mechanisms through which humans are able to use tools.

fRMI
The measurements performed will be the participant's brain activity, as well as behavioral measurements associated with the tasks performed (response time, correctness of the response). Brain activity measurements will be performed on the Siemens 3T system of the MRI department of CERMEP. The subject will perform the task under study while the level of brain activity is recorded. The functional examination will be subdivided into several parts according to its total length in order to spare the subject. The total duration of MRI acquisitions will be approximately 1 hour regardless of the axis.
