Welcome to the Numerical Cognition Lab at UCLouvain听听听
Main goals
We investigate the functional aspects of calculation and numerical processing and aim to find their neuroanatomical correlates:
听
(1) by the study of brain-damaged patient performance, of children with mathematical disabilities, and mental chronometric studies in healthy听children听and听adults.听
听听听听听
(2) by the study of听cerebral activation听with functional imaging techniques.

Laboratory
Equipment

We use Open Sesame, PsychoPy and E-Prime 1 and 2 with Microsoft Windows computers to measure performance (i.e., response latencies and error rates) on various computerized tasks with healthy participants and brain-damaged patients.

We use the brain imaging scanner facilities (3T Achieva, Philips Medical Systems) at the Cliniques universitaires St-Luc (UCLouvain) to record brain activity during various cognitive tasks. |
 |
Transcranial Magnetic Stimulation (TMS) is a non-invasive technique investigating the extent to which a brain area necessarily contributes to a specific cognitive process by causing a temporary and reversible impairment of this process by applying locally a small magnetic field over the scalp. We use the TMS facilities from the CoAction Lab (UCLouvain/IoNS/COSY) to interfere actively with cerebral processes during behavioural performance to investigate various numerical processes, such as numerosity processing or mental calculation. |

Along with the , and groups (UCLouvain), we have acquired an EyeLink 2000 eye tracker. This equipment works by measuring the distance between a light source reflection on the eye ball and the center of the pupil 2000 times a second. |

We use the virtual reality facility from . The system records room body position and limb actions wirelessy using a Polhemus Liberty Latus 120HZ Motion Analysis System, and hand actions using 5DT Data Gloves. The system records physical movements, and synchronizes visual virtual movements displayed in a 3D in the head mounted display. |
