The objective is to evaluate clinical characteristics and cerebral alterations in Parkinson's disease (PD) patients with diurnal visual hallucinations (VHs). Assessment was performed using magnetic resonance image (MRI) and voxel-based morp...
Sustained attention to spontaneous thumb sensations activates brain somatosensory and other proprioceptive areas [0.03%]
持续关注自发性拇指感觉激活脑体感和其它位置觉区域
Clemens C C Bauer,José-Luis Díaz,Luis Concha et al.
Clemens C C Bauer et al.
The present experiment was designed to test if sustained attention directed to the spontaneous sensations of the right or left thumb in the absence of any external stimuli is able to activate corresponding somatosensory brain areas. After v...
Motor planning in Parkinson's disease patients experiencing freezing of gait: the influence of cognitive load when approaching obstacles [0.03%]
帕金森病伴步态冻结患者的运动计划：接近障碍物时认知负荷的影响

Freezing of gait (FOG) in Parkinson's disease (PD) is typically assumed to be a pure motor deficit, although it is important to consider how an abrupt loss of gait automaticity might be associated with an overloaded central resource capacit...

Preparatory attention (PA) is the ability to allocate attention to a stimulus prior to its occurrence and is a crucial component of attentional control. We investigated the role of brain hemispheres in PA using an experimental test in which...
Neural correlates of viewing paintings: evidence from a quantitative meta-analysis of functional magnetic resonance imaging data [0.03%]

Task preparation and neural activation in stimulus-specific brain regions: an fMRI study with the cued task-switching paradigm [0.03%]
任务准备和特定刺激脑区的神经激活：一种提示的任务转换功能磁共振研究
Yiquan Shi,Thomas Meindl,André J Szameitat et al.
Yiquan Shi et al.
To investigate the role of posterior brain regions related to task-relevant stimulus processing in task preparation, we used a cued task-switching paradigm in which a pre-cue informed participants about the upcoming task on a trial: face di...
Posterior P1 and early frontal negativity reflect developmental changes in attentional distraction during adolescence [0.03%]
顶叶P1和额叶早期负波反映注意力分散在青春期的发展变化
Wenhai Zhang,Hong Li,Jie Chen et al.
Wenhai Zhang et al.
Previous studies in adults have revealed that attentional distraction modulates the late positive potential (LPP) during emotion regulation. To determine whether early visual components reflect developmental changes in attentional distracti...
Problems in planning bimanually incongruent grasp postures relate to simultaneous response specification processes [0.03%]
与同时响应规范过程有关的双臂计划不一致抓地姿势的问题

The purpose of the current experiments was to examine whether the problems associated with grasp posture planning during bimanually incongruent movements are due to crosstalk at the motor programming level. Participants performed a grasping...
Subthalamic deep brain stimulation restores automatic response activation and increases susceptibility to impulsive behavior in patients with Parkinson's disease [0.03%]
丘脑底核深部电刺激恢复了帕金森病患者的自动反应激活并增加了冲动行为的易感性
