The effects of bromazepam over the central and frontal areas during a motor task : an EEG study . The present study investigates the influence of bromazepam while executing a motor task . Specifically , we intend to analyze the changes in alpha absolute power under two experimental conditions , bromazepam and placebo . We also included analyses of theta and beta frequencies . We collected electroencephalographic data before , during , and after motor task execution . We used a Two Way ANOVA to investigate the condition ( PL × Br6 mg ) and moment ( pre and post ) variables for the following electrodes : Fp1 , Fp2 , F7 , F3 , Fz , F4 , F8 , C3 , CZ and C4 . We found a main effect for condition on the electrodes FP1 , F7 , F3 , Fz , F4 , C3 and CZ , for alpha and beta bands . For beta band we also found a main effect for condition on the electrodes Fp2 , F8 and C4 ; for theta band we identified a main effect for condition on C3 , Cz and C4 electrodes . This finding suggests that the motor task did not have any influence on the electrocortical activity in alpha , and that the existing modifications were a consequence due merely to the drug use . Despite its anxiolytic and sedative action , bromazepam did not show any significant changes when the individuals executed a finger extension motor task .
