Scores on neuropsychological tests for patients JPL, EP, LL, and EG.

Tests: BECS GRECO Semantic Battery: Merck et al. (2011); French celebrities questionnaire: Belliard et al. (2001); GDS: Yesavage et al. (1983); Grober and Buschke (1987); Mill Hill test: Deltour (1993); Mattis: dementia rating scale (Mattis, 1976); MMSE: Mini-Mental Status Exam (Folstein et al., 1975); Rey complex figure: Rey (1970); Semantic Knowledge Task: Desgranges et al. (1996); Picture naming: LEXIS (de Partz, 2001); TMT: Trail Making Test (Reitan, 1958).Note: The Semantic Knowledge Task was proposed to patients from Caen (JPL, EP, LL); the BECS GRECO Semantic Battery was proposed to the patient from Rennes (EG). On the Semantic Knowledge Task, performances had to be maximum to be considered unimpaired (i.e., standard deviation in control group equals zero). Hence, if patients did not obtain the maximum score, their performance was impaired (noted “pathological” in the Table). The French celebrities questionnaire was not proposed to EP at the time she participated in this fMRI study.Results were considered as significant when z>±1.96, pScores on neuropsychological tests for patients JPL, EP, LL, and EG.
