Simultaneous audio and visual stimulation was applied. The visual stimulation was 8Hz reversing chequerboard (yellow and blue squares) with 30s off, 30s on. The auditory stimulation was a recording of a radio discussion programme, with 45s off, 45s on. TR=3, TE=30ms, flip=90. Thanks to Dave Homfray for setting up and running the stimulation, Arthur Magill for running the scanner and Jonathan Marchini for donating his brain.
Analysis was carried out with FEAT (FMRI Expert Analysis Tool). Activation is shown superimposed on a structural scan taken during the same session as the FMRI experiment.
2D colour overlays are generated using the overlay, slices and slicer programs from FSL. Also these can be generated using the Feat -> Utils -> High-res FEAT stats colour rendering mini-GUI. The above programs primarily produce PPM or PNG format 2D pictures. The convert program bundled with FSL can convert to GIF format if necessary. GIF format 2D images can be merged into a GIF movie with the gifmerge program bundled with FSL. To produce 3D surface renderings you need other software such as MRIcro, AFNI/SUMA or mri3dX.
