Neural Synchronisation and Information Transmission in Delay-coupled Neuronal Networks

Neural synchrony is a widely observed phenomenon in the brain and it has been proposed that synchronisation of different brain rhythms might play a key role in integrating information from different brain regions. In this in silico study, I focus on particular motifs modelling thalamo-cortical connections. Parameter spaces of conduction delays and synaptic conductances are explored to study the synchrony regime of these motifs. Furthermore, I directly modulate a signal injected to one of the neurons in a network and examine how well the information of a signal modulation can be transmitted to other neurons in the network by using a cross-correlation function.
