Development of bottom-up and top-down communication in visual and multisensory cortical networks in humans (B11*)

本研究将检验人类视觉和多感觉神经网络的两个假设：(1)自上而下的沟通发展滞后于自下而上的加工发展；(2)自上而下加工的发展对早期感官经验的依赖程度大于自下而上加工的发展。两种脑电图范式，视觉注意和多感官范式，将在人类成人中发展。他们将连续适应儿童（5-11岁，前瞻性发展方法）和视力恢复个体（回顾性发展方法），分别验证这两个假设。

The present study will test two hypotheses in human visual and multisensory neural networks: (1) The development of top-down communication lags behind the development of bottom-up processing; (2) the development of top-down processing depends to a larger extent on early sensory experience than the development of bottom-up processing. Two EEG paradigms, a visual attention and a multisensory paradigm, will be developed in human adults. They will consecutively be adapted to children (5-11 year old, prospective developmental approach) and sight-recovery individuals (retrospective developmental approach) to test these two hypotheses, respectively.
