  7. This experiment was conducted by Geraint Rees under the direction of
  8. Karl Friston and the FIL methods group. The purpose was to explore new
  9. equipment and techniques. As such it has not been formally written up,
  10. and is freely available for personal education and evaluation purposes.
  11. These whole brain BOLD/EPI images were acquired on a modified 2T
  12. Siemens MAGNETOM Vision system. Each acquisition consisted of 64
  13. contiguous slices (64x64x64 3mm x 3mm x 3mm voxels). Acquisition took
  14. 6.05s, with the scan to scan repeat time (RT) set arbitrarily to 7s.
  15. 96 acquisitions were made (RT=7s), in blocks of 6, giving 16 42s
  16. blocks. The condition for successive blocks alternated between rest and
  17. auditory stimulation, starting with rest. Auditory stimulation was
  18. bi-syllabic words presented binaurally at a rate of 60 per minute. Due
  19. to T1 effects it is advisable to discard the first few scans (there were
  20. no "dummy" lead-in scans).
  21. A structural image was also acquired.
