Chimeras in an adaptive neuronal network with burst-timing-dependent plasticity
The synchronized behavior of neurons depends on the structure and function of the synaptic connections between them. One of the activity-dependent synaptic modifications is the burst-timing-dependent plasticity, which relies on the latencies of the presynaptic and postsynaptic bursts. In this paper, we, therefore, study the collective behavior of a neuronal network with burst-timing-dependent plasticity, in particular, focusing on the emergence of chimera states. We consider separately non-local and global couplings, which have substantial effects on the collective dynamics. We show that the considered burst-timing-dependent plasticity leads to different behavior from static networks. The histogram of the synaptic strengths, in particular, reveals a different evolution of the chimera states in comparison to the development of synchronous and asynchronous states.
