FIG 2. MR image and proton spectra from an activated brain region of one dyslexic subject.
A, MR image with white box indicating the brain region measured with MR spectroscopy.
B, Proton MR spectrum from the white box brain region during the passive listening task.
C, Proton MR spectrum from the white box brain region during the phonological task. The intensity axis of the spectra is scaled so that the lactate can be seen easier; however, choline (Cho) and NAA are scaled off the figure. Note the increase in the lactate peaks during the phonological task as compared with passive listening.
