Effects of Methylphenidate on performance of a practical pistol shooting task: a quantitative electroencephalography (qEEG) study
Background The present study examined absolute alpha power using quantitative electroencephalogram ( qEEG ) in bilateral temporal and parietal cortices in novice soldiers under the influence of methylpheni date ( MPH )  during the preparatory aim ing period in a practical pistol-shooting task . We anticipated higher bi-hemispheric cortical activation in the preparatory period relative to pre-shot baseline in the methylpheni date group when compared with the control group because methylpheni date has been shown to enhance task-related cognitive functions . Methods Twenty healthy , novice soldiers were equally distributed in control ( CG ; n = 10 ) and MPH groups 10 mg ( MG ; n = 10 ) using a r and omized , double blind design . Subjects performed a pistol-shooting task while electroencephalographic activity was acquired . Results We found main effects for group and practice blocks on behavioral measures , and interactions between group and phases on electroencephalographic measures for the electrodes T3 , T4 , P3 and P4 . Regarding the behavioral measures , the MPH group demonstrated significantly poorer in shooting performance when compared with the control and , in addition , significant increases in the scores over practice blocks were found on both groups . In addition , regarding the electroencephalographic data , we observed a significant increase in alpha power over practice blocks , but alpha power was significantly lower for the MPH group when compared with the placebo group . Moreover , we observed a significant decrease in alpha power in electrodes T4 and P4 during PTM . Conclusion Although we found no correlation between behavioral and EEG data , our findings show that MPH did not prevent the learning of the task in healthy subjects . However , during the practice blocks ( PBs ) it also did not favor the performance when compared with control group performance . It seems that the CNS effects of MPH dem and ed an initial readjustment period of integrated operations relative to the sensorimotor system . In other words , MPH seems to provoke a period of initial instability due to a possible modulation in neural activity , which can be explained by lower levels of alpha power ( i.e. , higher cortical activity ) . However , after the end of the PB1 a new stabilization was established in neural circuits , due to repetition of the task , result ing higher cortical activity during the task . In conclusion , MPH group performance was not initially superior to that of the control group , but eventually exceeded it , albeit without achieving statistical significance
