Outcomes

Primary Outcome Measures

Performance in the implicat task
Reaction time and accuracy will be registered for this categorization task. This task will be used in patients with FTD and in healthy controls (n=60). Participants will come only once during one day ot the research centre.
Performance in the Similitude task
Reaction time and accuracy will be recorded while healthy subjects perform this categorization task, after a session of rTMS or during on line TMS (n=40). Participants will come 3 to 5 times at the research centre in a maximum period of 4 months.

Secondary Outcome Measures

recording of EEG
EEG will be recorded in patients with FTD and in healthy controls for an analysis of event related potentials. Participants will come only once during one day a the research centre.
Analysis of MRI
T1 MRI will be recorded for VBM analysis in patients with FTD and healthy controls. Participants will come only once during one day at the research centre

5. Study Description

Brief Summary
Frontal patients are impaired in categorisation and analogical reasoning tasks, and different functional imaging studies from our group have shown the involvement of the prefrontal cortex in categorisation and analogy tasks. The aim of this project is to test our hypotheses about the role of the prefrontal cortex in explicit and implicit categorisation and analogy tasks.
