Abstract: Understanding how local interactions between neurons give rise to high-level structures in the brain is one of the key open questions in neuroscience. This thesis investigates discrete-time, weighted digraph models of the connectome, which not only provide insight into biological neural networks, but also form the backbone of modern artificial neural networks. The primary model of interest is the k-cap process, a recurrent neural network employing k-winners-take-all (k-WTA) as a nonlinear gating function; this mechanism models firing rate regulation via global lateral inhibition. By exploring the computational properties arising from this model, this work aims to offer insights into the emergence of structures in the connectome.
