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...
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...
Effects of a cognitive modulator in the theta and alpha asymmetry during a type...
Cunha,Marlo; Machado,Sergio; Miana,Luiz Cláudio; Machado,Dionis; Bastos,Victor Hugo; Velasques,Bruna; Cagy,Maurício; Basile,Luis F.; Piedade,RobertoThis study aimed to elucidate cortical mechanisms and to identify the areas where occur such mechanisms due to interaction between bromazepam and motor learning. The sample was composed of 45 healthy subjects randomly distributed in 3 groups: placebo (n=15), bromazepam 3 mg (n=15) or bromazepam 6 mg (n=15). To perform the experimental task, subjects sat comfortably at a distance of approximately 20 cm from the ...
Alzheimer's disease and implicit memory
Machado,Sergio; Cunha,Marlo; Minc,Daniel; Portella,Claudio Elidio; Velasques,Bruna; Basile,Luis F.; Cagy,Maurício; Piedade,Roberto; Ribeiro,PedroSpecific neuropsychiatric disorders, such as Alzheimer's disease (AD) affect some forms of memory while leaving others relatively intact. In this review, we investigate particularities of the relationship between explicit and implicit memories in AD. It was found that implicit memory is preserved in AD, irrespective of the task used; in other words, there was not interference from explicit memory. In addition, ...
