Single subject epoch (block) auditory fMRI activation data

Overview

This experiment was conducted by Geraint Rees under the direction of Karl Friston and the FIL methods group. The purpose was to explore equipment and techniques in the early days of our fMRI experience. As such it has not been formally written up, and is freely available for personal education and evaluation purposes.

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 with bi-syllabic words presented binaurally at a rate of 60 per minute. The functional data starts at acquisiton 4, image fM00223_004. Due to T1 effects it is advisable to discard the first few scans (there were no "dummy" lead-in scans).

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.
