Abstract

The neural correlates of procedural learning were studied using functionalmagnetic resonance imaging (fMRI) and the mirror reading paradigm. The aimof the study was to investigate a presumed learning-related change of activation in cortical areas that are involved in the performance of a nonmotorskill. Changes in cortical blood oxygenation contrast were recorded in 10 healthy subjects while they alternatively read visually presented single mirror script words and normal script words. Responses in naive subjects werecompared to those acquired after training of mirror script reading. The acquisition volume included the motor and premotor cortex, the parietal lobe and the occipital lobe including its inferior aspects. Striate and extrastriate visual areas, associative parietal cortex and the premotor cortex werebilaterally active during normal and mirror script reading. Significantly stronger activation during mirror reading was seen in BA7 and 40 (parietal associative cortex) and in BA6 (corresponding to the frontal eye fields). Simultaneous eye movement recordings indicated that activation in BA6 was related to processing components other than saccade frequency. After training, BA6 and BA7 exhibited a decrease of activation during mirror reading thatsignificantly exceeded nonspecific changes observed in the normal script control condition. The present findings confirm the hypothesis: of practice-related decrease of activation in task-related cortical areas during nonmotor procedural learning. (C) 2001 Elsevier Science B.V.
