| summary | In most natural systems spatial interactions are local and the spatiotemporal dynamics in these systems is described by partial differential equations. An important exception from this rule are neural structures, especially the human brain, where spatially remote areas are connected by white matter fiber tracts. These so-called heterogeneous connections cannot be captured by local derivatives and therefore neural systems need to be described by integral equations. We show first how modern imaging techniques can be used to find the brain structure as well as the main pathways that exist in the living human brain. Second, we will discuss how heterogeneous connections act as a control parameter that can induce pattern forming instabilities but also lead to pattern selection in different geometries. |
