Information about the world is represented in the brain by the combined activity of populations of many neurons. However, the basic principles underlying how such population activity codes information are largely unknown. Using the map from the eye to the brain of the zebrafish as a model, the project aims to combine experimental measurements of neural activity with mathematical modelling in order to discover these basic principles. Of particular interest is how these coding principles change during development and their plasticity after disruptions to the visual map. Besides improving our understanding of how brains process information, the knowledge gained could help optimise the design of brain-computer interfaces and artificial computing devices.

关于世界的信息在大脑中通过许多神经元群体的组合活动来表示。然而，此类人口活动如何编码信息的基本原理在很大程度上尚不清楚。该项目以斑马鱼眼睛到大脑的图谱为模型，旨在将神经活动的实验测量与数学建模结合起来，以发现这些基本原理。特别令人感兴趣的是这些编码原则在开发过程中如何变化以及它们在视觉图被破坏后的可塑性。除了提高我们对大脑如何处理信息的理解之外，获得的知识还可以帮助优化脑机接口和人工计算设备的设计。
