FIG 1. Composite maps (first order, see Table) show regional cerebellar activation during the four reading tasks. Column one compares the case task with the line task (C/L), column two compares the word rhyme task with the line task (WR/L), column three compares the non-word rhyme task with the line task (NWR/L), and column four compares the category task with the line task (CT/L). There is a progressive increase in demand on cognitive processing in going from column one to column four. Numbers indicate cerebellar regions that were more active (P = .005, red-yellow scale) in a reading task compared with the line task; letters indicate areas of the cerebellum that were more active (P = .005, blue-purple scale) in the line task compared with a reading task. 1, anterior aspect of the simple lobule; 2, middle and lateral aspects of the posterior superior fissure and adjacent simple lobule and superior semilunar lobule; 3, middle aspect of the horizontal fissure and adjacent superior semilunar lobule and inferior semilunar lobule; 4, middle aspect of the prepyramidal fissure and adjacent inferior semilunar lobule; 5, posterior and lateral aspects of the horizontal fissure and adjacent superior semilunar lobule and inferior semilunar lobule; 6, posterior and lateral aspects of the posterior superior fissure and adjacent simple lobule and superior semilunar lobule; 7, posterior aspect of inferior semilunar lobule; and 8, posterior and medial aspects of the posterior superior fissure and adjacent simple lobule and superior semilunar lobule. a, inferior vermis; b, postpyramidal fissure and medial aspect of the tonsils; c, biventer lobule; d, medial aspect of the biventer lobule; and e, the middle and posterior aspects of the horizontal fissure and adjacent superior semilunar lobule and inferior semilunar lobule. Section locations in each column from superior to inferior correspond to the following approximate y axis positions of the Talairach atlas: -40, -50, -60, -70, -80, and -90.
