Before revision:  We study neuronal synchronisation by means of a randomly network with excitatory and inhibitory synapses, where the neuron model is given by the adaptive exponential integrate-and-fire . In our network , we verify that the decrease in the influence of inhibition can generate synchronisation  from a pattern of desynchronised spikes.
