Interplay of synchronization and cortical input in models of brain networks
It is well known that synchronization patterns and coherence have a major
role in the functioning of brain networks, both in pathological and in healthy
states. In particular, in the perception of sound, one can observe an increase
in coherence between the global dynamics in the network and the auditory input.
In this perspective article, we show that synchronization scenarios are
determined by a fine interplay between network topology, the location of the
input, and frequencies of these cortical input signals. To this end, we analyze
the influence of an external stimulation in a network of FitzHugh-Nagumo
oscillators with empirically measured structural connectivity, and discuss
different areas of cortical stimulation, including the auditory cortex.
