  • 2x2 factorial event-related fMRI
  • One session (one subject)
  • (Famous vs. Nonfamous) x (1st vs 2nd presentation) of faces against baseline of chequerboard
  • 2 presentations of 26 Famous and 26 Nonfamous Greyscale photographs, for 0.5s, randomly intermixed, for fame judgment task (one of two right finger key presses).
  • Parameteric factor "lag" = number of faces intervening between repetition of a specific face + 1
  • Minimal SOA=4.5s, with probability 2/3 (ie 1/3 null events)
  • Continuous EPI (TE=40ms,TR=2s) 24 descending slices (64x64 3x3mm2), 3mm thick, 1.5mm gap
