             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.",
