rTMS treatment for depression in Parkinson`s disease increases BOLD responses in the left prefrontal cortex
(CAMBRIDGE UNIV PRESS, 2008)
The mechanisms underlying the effects of antidepressant treatment in patients with Parkinson`s disease (PD) are unclear. The neural changes after successful therapy investigated by neuroimaging methods can give insights ...
BacAv, a new free online platform for clinical back-averaging
(2020)
Objective. The back-average technique is very useful to study the relation between the activity in the cortex and the muscles. It has two main clinical applications, Bereitschaftspotential (BP) recording and myoclonus ...
Circuits for State-Dependent Modulation of Locomotion
(Frontiers Media, 2021-11)
Brain-wide neural circuits enable bi- and quadrupeds to express adaptive locomotor behaviors in a context- and state-dependent manner, e.g., in response to threats or rewards. These behaviors include dynamic transitions ...
Monitoring multiple cortical regions during walking in young and older adults: Dual-task response and comparison challenges
(2019-01-01)
Performance of several tasks simultaneously (dual-tasks) is common in everyday walking. Studies indicate that dual-task walking performance declines with age together with cognitive function, but neural mechanisms underpinning ...
Brain mechanisms of serial and parallel processing during dual-task performance
(Society for Neuroscience, 2008-12)
The psychological refractory period (PRP) refers to the fact that humans typically cannot perform two tasks at once. Behavioral experiments have led to the proposal that, in fact, peripheral perceptual and motor stages ...
Transcranial Direct Current Stimulation Modulates Neuronal Networks in Attention Deficit Hyperactivity Disorder
(Springer, 2017-09)
Anodal transcranial direct current stimulation (tDCS) of the prefrontal cortex has been repeatedly shown to improve working memory (WM). Since patients with attention deficit hyperactivity disorder (ADHD) are characterized ...
Functional Evidence for Memory Stabilization in Sensorimotor Adaptation: A 24-h Resting-State fMRI Study
(Oxford University Press, 2017-03)
Adaptation learning is crucial to maintain precise motor control in face of environmental perturbations. Although much progress has been made in understanding the psychophysics and neurophysiology of sensorimotor adaptation ...
THE ROLE OF THE SUPERIOR COLLICULUS IN PREDATORY HUNTING
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
Combining the results of behavioral, neuronal immediate early gene activation, lesion and neuroanatomical experiments, we have presently investigated the role of the superior colliculus (SC) in predatory hunting. First, ...
A influência do uso da realidade virtual no padrão de ativação cortical e no desempenho de atividade de dupla tarefa em idosos
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM FISIOTERAPIA, 2019-08-30)
(Introduction) Dual task (TD) activities combine tasks with cognitive and motor characteristics,
being very present in daily life and predispose the older adults to falls. In this sense, investigating
motor performance ...
