Before revision:  Finally, in the presence of iSTDP we investigate the effects of network architecture on BS by varying the symmetric attachment degree l^* and the asymmetry parameter \Delta l in the SFN , and Matthew effects in inhibitory synaptic plasticity are also found to occur by varying l^* and \Delta l .
