AB  - Selecting the adequate alternative in choice situations may involve an inhibition 
      process. Here we assessed response implementation during the reaction time of a 
      between-hand choice task with single- or paired-pulse (3 or 15 ms interstimulus 
      intervals [ISIs]) transcranial magnetic stimulation of the motor cortex. The 
      amplitude of the single-pulse motor evoked potential (MEP) initially increased 
      for both hands. At around 130 ms, the single-pulse MEP kept increasing for the 
      responding hand and decreased for the nonresponding hand. The paired-pulse MEP 
      revealed a similar pattern for both ISIs with no effect on short intracortical 
      inhibition and intracortical facilitation measures. The results suggest that the 
      incorrect response implementation was selectively suppressed before execution of 
      the correct response, preventing errors in choice context. The results favor 
      models assuming that decision making involves an inhibition process.
