Advanced Event-related fMRI - Repetition priming - SPM2


  • Overview of the dataset, and step-by-step description of spatial processing steps:
  • Access to whole dataset:
  • This archive contains the raw fMRI data and, importantly, a batch file (batch.m) for batching the spatial processing and statistical analyses.
  • Access to smoothed, normalised, realigned images required for statistical analysis (ie. whole dataset without original Analyse format images and intervening spatially processed data)


    Repetition priming for famous and nonfamous faces

    Created R. Henson, 8/7/00, WDCN & ICN, UCL (Adapted for SPM2, May 2003)

    One subject's data from Henson, R.N.A., Shallice, T., Gorno-Tempini, M.-L. and Dolan, R.J. (2002) Face repetition effects in implicit and explicit memory tests as measured by fMRI. Cerebral Cortex, 12, 178-186. - FOR TEACHING PURPOSES ONLY - PLEASE DO NOT CITE WITHOUT PERMISSION

    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
