The effects of bromazepam over the central and frontal areas during a motor tas...
Fortunato,Suzete; Tanaka,Guaraci Ken; Araújo,Fernanda; Bittencourt,Juliana; Aprigio,Danielle; Gongora,Mariana; Teixeira,SilmarThe 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 condi...
Alpha power oscillation in the frontal cortex under Bromazepam and Modafinil ef...
Aprigio,Danielle; Adolfo,Washington; Bittencourt,Juliana; Gongora,Mariana; Teixeira,Silmar; Basile,Luis Fernando; Budde,Henning; Cagy,MauricioABSTRACTObjective Our aim was to investigate and compare the neuromodulatory effects of bromazepam (6 mg) and modafinil (200 mg) during a sensorimotor task analyzing the changes produced in the absolute alpha power.Method The sample was composed of 15 healthy individuals exposed to three experimental conditions: placebo, modafinil and bromazepam. EEG data were recorded before, during and after the execution of ...
Lower trait frontal theta activity in mindfulness meditators
Tanaka,Guaraci Ken; Peressutti,Caroline; Teixeira,Silmar; Cagy,Mauricio; Piedade,Roberto; Nardi,Antonio Egídio; Ribeiro,Pedro; Velasques,BrunaAcute and long-term effects of mindfulness meditation on theta-band activity are not clear. The aim of this study was to investigate frontal theta differences between long- and short-term mindfulness practitioners before, during, and after mindfulness meditation. Twenty participants were recruited, of which 10 were experienced Buddhist meditators. Despite an acute increase in the theta activity during meditatio...
Electroencephalographic findings in panic disorder
Carvalho,Marcele Regine de; Velasques,Bruna Brandao; Cagy,Mauricio; Marques,Juliana Bittencourt; Teixeira,Silmar; Nardi,Antonio Egidio; Piedade,RobertoSome studies have reported the importance of electroencephalography (EEG) as a method for investigating abnormal parameters in psychiatric disorders. Different findings in time and frequency domain analysis with regard to central nervous system arousal during acute panic states have already been obtained. This study aimed to systematically review the EEG findings in panic disorder (PD), discuss them having a cu...
Cognitive mechanisms and motor control during a saccadic eye movement task: evi...
Diniz,Claudia; Velasques,Bruna; Bittencourt,Juliana; Peressutti,Caroline; Machado,Sergio; Teixeira,Silmar; Santos,Joana Luz; Salles,José InácioThe saccadic movement is an important behavioral measure used to investigate several cognitive processes, including attention and sensorimotor integration. The present study aimed at investigating changes in beta coherence over frontal, motor, occipital, and parietal cortices during the performance of two different conditions of a prosacadic paradigm. The conditions involved a different pattern of stimulus pres...
