Research Interests

My research projects aim at defining the functional components of calculation and number processing and at finding their neuroanatomical correlates. My work is carried out in three directions using different but complementary methodologies: the study of cerebral activations with functional imaging techniques, the study of brain-damaged patients performance, and mental chronometric studies in healthy adults. Integrating the functional and neuroanatomical levels of analysis in the same theoretical questioning seems to me essential to further our understanding of cognitive processes and to improve the validity of current models of numerical cognition.

In the last years, I have been funded by grants from the National Fund for Scientific Research (Belgium), the Fonds de Developpement Scientifique (UCLouvain), and the PAI/IUAP Program from the Belgian Government.

听Research Interests :

听听 My master degree was in Neuropsychology at the 小瓢虫传媒 (UCL, Belgium). I did my last year dissertation with Xavier Seron and Aliette Lochy on the switching between Arabic and verbal notations during the writing of numbers. I started a doctoral degree with Xavier Seron on the study of hemispheric lateralization of number representation and the influence of finger counting on number representation in adults. My method of choice was transcranial magnetic stimulation (TMS), a technique that I learned with Etienne Olivier in the Laboratory of Neurophysiology (UCL) and with Tomas Paus during a stay at the Montreal Neurological Institute (McGill University, Canada). Using TMS, I confirmed the dominant role of the left parietal cortex in exact number comparison and evidenced increased corticospinal excitability (CSE) in hand motor circuits during serial processing of numbers and letters, suggesting a link between the representation of fingers and ordered series.

听听 I also participated to the investigation of the neural representation of simple motor acts, such as grasping, and complex actions like tool use (with Etienne Olivier and Marco Davare). Using electromyographic recordings and kinematic measurements, I collected evidence that number magnitude can interfere with grip aperture, in line with the idea that the representation of numerical and physical magnitudes share common processes (with听听and听). I pursued this idea in a number of collaborative projects using functional magnetic resonance imaging (fMRI) and TMS to investigate the functional overlap between number, time and space representations in the parietal cortex (with听听and听).

听听 During my post-doc, I used dual tasks, fMRI and CSE measurements to specificy the role of motor representations in mental arithmetic (with听听and听) and action verb understanding (with Manuela Piazza). I looked at motor imagery and action understanding in a person with a congenital absence of upper limbs (with Agnesa Pillon and Gilles Vannuscorps) and worked as a fellow researcher at the CIMeC (University of Trento, Italy) where I tried to combine habituation paradigms with fMRI in order to reveal the tuning properties of parietal and frontal regions in response to number or finger change (with Manuela Piazza).

听听 More recently, I contributed to the development of a TMS lab at Ghent University (Department of Experimental Psychology, UGent, Belgium) and iniated several projects with Wim Fias and Marcel Brass where we investigate cognitive control processes in stop signal and switching tasks. My goal is to extend current knowledge of control processes to complex cognitive tasks, such as mental arithmetic, with a great interest for the role of the prefrontal cortex as an interface between stimulus-response association in the parietal cortex and response execution in the motor cortex.
