Study summary

The purpose of this study is to investigate the effect of drug A on its own and when it is given in combination with drug B on markers of brain activity. The study will

  1. Assess the effects of drug A and drug B on muscle movement after brain stimulation;
  2. Examine how the body handles (absorbs, distributes, breaks down and gets rid of) drug A and drug B when given in combination;
  3. Examine the safety of drug A and drug B when given together.
