Extract:

Activation of human language processing brain regions after the presentation of random letter strings demonstrated with event-related functional magnetic resonance imaging is a fMRI experiment about word processing. The design of the experiment is even-related in contrast to previous studies of block-design, e.g., the PET experiment by Petersen et al.[1]

[edit] Subjects

Subject group (help)
Healthy right-handed volunteers
Subjects/♂/♀: 12 / 7 / 5
Age: 26.5 (22–35)

Databases:

A group of 12 healthy right-handed volunteers with 7 males and 5 females were included in the study. The group had a mean age of 26.5 with a range from 22 to 35.

Twelve healthy right-handed volunteers and presumably Germans from the Bonn or Tübingen area.

[edit] Dataanalysis

Data analysis was perform with SPM96 with spatial normalization to the T1-template.
