abstract = "Brain plasticity refers to brains ability to change neuronal
connections, as a result of environmental stimuli, new
experiences, or damage. In this work, we study the effects of the
synaptic delay on both the coupling strengths and synchronization
in a neuronal network with synaptic plasticity. We build a network
of HodgkinHuxley neurons, where the plasticity is given by the
Hebbian rules. We verify that without time delay the synapses
become regulated by both the nature (excitatory or inhibitory) and
the frequency of the presynaptic and postsynaptic neuron. A
presynaptic excitatory (inhibitory) neuron with higher (lower)
frequency enhances the synaptic strength if the postsynaptic
excitatory (inhibitory) neuron has lower (higher) frequency. When
the delay is increased the network presents a non-trivial
topology. Regarding the synchronization, only for small values of
the synaptic delay this phenomenon is observed.",
