Primary Outcome Measures
NameTimeMethod
<p>The main endpoint is the behavioural score on the verbal learning task, the<br /><br>continuous recognition memory task, and the spatial memory task. Secondary, the<br /><br>event-related potentials during those tasks will be analysed. </p><br>
Secondary Outcome Measures
NameTimeMethod
<p>A further important parameter is the change in behavioural and brain response<br /><br>to the choice reaction time task, since this measures a possible sedative<br /><br>effect of the two manipulations. Finally, we will measure the event-related<br /><br>potential during a novelty oddball task to assess the role of both<br /><br>neurotransmitters in novelty processing.</p><br>
