Abstract
Neurons are the fundamental units of the nervous system, responsible for receiving sensory input from the external world, processing them in a non-linear manner and transmits information to neighbouring neurons which are connected to each other with synapses. Synapses transmit the information via electrochemical signals. Together with brain?s malleability, which provides sophisticated learning capabilities, one of the most complex systems that have ever existed is constituted. In this work, a generalised plasticity model based on synaptic weights is formulated and compared with the classic one. This model enables multi-synapses and propagation delay characterization in a spiking neural network. The main objective of this project is to study how the delay distribution of a network determines its topological features after a learning process. This study is made, both, for small motives and large networks in order to understand the internal machinery of the model and to study its effect on a larger scale. Furthermore, the steady-state large network results are compared with the steady-state results obtained in situations where specific neurons are stimulated. This last configuration represents the learning process of one specific stimulus which feeds the network. This project opens the door to future plasticity studies with propagation delay implementation, or in other words, allows the study of plasticity in spatial arrangements of neurons.
