Pascal Fries will investigate the patterns of rhythmic neuronal synchronization within and between brain areas during a serial visual search task. The monkeys’ behavioural performance will be related to the strength, phase and directedness of synchronization assessed with highly flexible, subdural grids and/or penetrating shaft electrodes that cover large parts of one cortical hemisphere, extending from frontal, motor, and parietal cortex up to occipital cortex. These flexible electrodes have been pioneered in the Fries lab and may turn out to be useful also for other members of the RU interested in inter-areal cortical interactions.

Pascal Fries将研究在连续视觉搜索任务期间大脑区域内和之间的节律性神经元同步模式。猴的行为表现将与使用高度灵活的硬膜下网格和/或穿透轴电极评估的同步的强度、相位和定向性相关，所述电极覆盖一个皮质半球的大部分，从额叶、运动和顶叶皮质延伸到枕叶皮质。这些灵活的电极已率先在弗里斯实验室，并可能成为有用的RU的其他成员感兴趣的区域间皮层的相互作用。
