Primary Outcome Measures

Name	Time	Method
<p>The primary EEG study parameters are the latency (in miliseconds) and amplitude<br /><br>(in microvolts) of the N100 component of the AEP response. The study parameters<br /><br>will be compared between the three study groups.</p><br>

Secondary Outcome Measures

Name	Time	Method
<p>The secundary study parameters are the latency (in miliseconds) and amplitude<br /><br>(in microvolts) of the N200 and P300 components of the AEP response in the EEG<br /><br>recordings. The frequency spectrum of the brain activity is also a study<br /><br>parameter. The study parameters will be compared between the three study<br /><br>groups.</p><br>
