To explore how we perceive objects that we manipulate or touch we performed electro-physiological recordings in behaving non-human primates and identified the essential connectivity patterns of the fronto-parietal grasp network in a fMRI resting state analysis. We now plan to further study the planning and execution of grasping actions in the primate brain by (i) using monkey fMRI and a delayed hand grasping task to explore which cortical areas are involved, (ii) using chemical and optogenetic inactivation of sensory cortical areas to understand their involvement during behavioural tasks, and (iii) developing a recurrent neural network model which will explain the processing of visual and tactile input signals in these areas.

为了探索我们如何感知我们操纵或触摸的物体，我们在行为非人类灵长类动物中进行了电生理记录，并在fMRI静息状态分析中确定了额顶叶抓握网络的基本连接模式。我们现在计划进一步研究灵长类动物大脑中抓握动作的规划和执行，方法是：（i）使用猴子的fMRI和延迟手抓握任务来探索哪些皮层区域参与其中，（ii）使用感觉皮层区域的化学和光遗传学失活来了解它们在行为任务中的参与，及（iii）发展一个循环神经网络模型，以解释这些区域对视觉及触觉输入信号的处理。
