port of the display PC which are recorded in a separate EEG channel. These
codes are used in order to synchronize the EEG data with the stimuli. Since
this is a mobile system, we`re using a laptop in order to present the stimuli.
Recently, we had to replace our laptop but couldn`t find any new laptops with
built-in parallel port. <o:p></o:p></span></p>
