Figure 1: Hypothesis. A. Due to the nonlinear activity profiles of single neurons and the complex connectivity profiles of neural circuits, we hypothesized that neural manifolds underlying behaviour should be nonlinear. B. We predicted that, if the geometry of neural manifolds indeed reflects circuit properties, neural manifolds from cytoarchitecturally different brain regions would exhibit distinct degrees of nonlinearity. C. We further predicted that more complex behavioural tasks that require a broader range of activity patterns will make the intrinsic nonlinearity of neural manifolds more apparent.
