Hierarchy for action: sensation perception & intention

目标导向行动是人们在一生中获得和执行的最基本但也是必要的行为之一。然而，即使是伸手抓住物体(咖啡杯或汽车钥匙)的简单动作也需要感觉、认知和神经肌肉系统之间的相互作用。这些系统必须共同执行一些任务：必须从感觉环境中有选择地收集关于物体的信息，必须选择和准备反应，必须快速而准确地控制运动。具体地说，我们将检查不同类型的视觉信息(例如，纹理、眼睛位置)的整合、组织和优先顺序，以及有意识地获取这些信息源的程度。因此，本研究计划的目标是研究大脑如何在结构和功能上管理复杂的感觉输入的组织，以产生连贯和有目的的行动。

Goal-directed action is one of the most basic yet necessary behaviours for people to acquire and perform throughout their lifetime. However, even the simple act of reaching to grasp an object (coffee cup or car keys) requires interaction between the sensory, cognitive and neuro-muscular systems. These systems must jointly perform a number of tasks: information about objects must be selectively gathered from the sensory environment, responses must be selected and prepared, and movements must be rapidly and accurately controlled. Specifically, we will examine the integration, organization and precedence of different types of visual information (e.g., texture, eye-position), as well as the degree of conscious access to these information sources. Thus, the goal of the present research program is to investigate how the brain manages - both structurally and functionally - the organization of complex sensory inputs to produce coherent and purposeful action.
