abstract = {Our brains are formed by networks of neurons and other
cells which receive, filter, store and process information
and produce actions. The morphology of the neurons changes
through time as well as the connections between them. For
years the brain has been studied as a snapshot in time, but
today we know that the way it structurally changes is
strongly involved in learning, healing, and adaptation. The
ensemble of structural changes that neural networks present
through time is called structural plasticity. In this work,
I present structural plasticity from its neurobiological
foundations and the implementation of a model to describe
generation and optimization of connectivity in spiking
neural networks. I have targeted two relevant and open
questions in the computational neuroscience community: how
can we model biologically inspired structural changes in
simulations of spiking neural networks and how can we use
this model and its implementation to optimize brain
connectivity to answer specific scientific questions related
to healing, development, and learning. I present several
studies which explain the implementation of structural
plasticity in a well established neural network simulator
and its application on different types of neural networks.
In this thesis I have also defined the requirements and use
cases for the co-development of tools to visualize and
interact with the structural plasticity algorithm. Moreover,
I present two scientific applications of the structural
plasticity model in the clinical neuroscience and computer
science fields. In conclusion, my thesis provides the basis
of a software framework and a methodology to address complex
neuroscience questions related to plasticity and the links
between structure and function in the brain, with potential
applications not only in neuroscience but also for machine
learning and optimization.},
