TL;DR: Learning-related increases of cerebral blood flow were located in contralateral motor effector areas including motor cortex, supplementary motor area, and putamen, consistent with the hypothesis that nondeclarative motor learning occurs in cerebral areas that control limb movements.

TL;DR: Findings support the idea that parietal cortex is involved in activating possible responses on the basis of learned stimulus-response associations, and that prefrontal cortex is recruited when there is a need to select between competing responses.

TL;DR: The authors theorize that 2 neurocognitive sequence-learning systems can be distinguished in serial reaction time experiments, one dorsal (parietal and supplementary motor cortex) and the other ventral (temporal and lateral prefrontal cortex), which are relevant to issues of attentional effects on learning.

TL;DR: PET revealed the effects of stimulus characteristics on the neural substrate of motor learning, and areas supporting motor-sequence learning are contingent on both stimulus properties and attentional constraints.

TL;DR: Implicit sequence learning by the nondominant left hand was examined with the serial reaction time (SRT) task during functional brain imaging, and mirror transformation of the sequence by the right hand was associated with a marked increase in regional activity in the left motor cortex, consistent with a role for sequential transformation at this level of the motor output pathway.
