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