  <dc:description xmlns:ns0="xml" ns0:lang="en">Background: Motor imagery and actual movements share overlapping activation of  brain areas but little is known about task-specific activation of distinct motor pathways  during mental simulation of movements. For real contractions, it was demonstrated  that the slow(er) motor pathways are activated differently in ballistic compared to tonic  contractions but it is unknown if this also holds true for imagined  contractions.Objective: The aim of the present study was to assess the activity of fast  and slow(er) motor pathways during mentally simulated movements of ballistic and  tonic contractions.Methods: H-reflexes were conditioned with transcranial magnetic  stimulation at different interstimulus intervals to assess the excitability of fast and  slow(er) motor pathways during a) the execution of tonic and ballistic contractions, b)  motor imagery of these contraction types, and c) at rest.Results: In contrast to the fast  motor pathways, the slow(er) pathways displayed a task-specific activation: for  imagined ballistic as well as real ballistic contractions, the activation was reduced  compared to rest whereas enhanced activation was found for imagined tonic and real  tonic contractions.Conclusions: This study provides evidence that the excitability of  fast and slow(er) motor pathways during motor imagery resembles the activation  pattern observed during real contractions. The findings indicate that motor imagery  results in task- and pathway-specific subliminal activation of distinct subsets of  neurons in the primary motor cortex.</dc:description>
