The same ocurred with the total excitationand inhibition produced by the network, as is usually seen from Table 3. Lastly, as well as akin for the firing rate of RS excitatory neurons, the effect of modularity on the activity measures shown in Table three was not so powerful. For non-zero hierarchical levels, theFrontiers in Computational Neurosciencewww.frontiersin.orgSeptember 2014 | Volume 8 | Report 103 |Tomov et al.Sustained activity in cortical modelstotal inhibition and excitation made by a network and also the firing rate of its inhibitory neurons with otherwise fixed neuron kinds remained in the same range as to get a network with H = 0. The same was accordingly true for the distributions of your firing prices in the diverse forms of inhibitory neurons (not shown). Difference in total excitation and inhibition was also not strongly influenced by merely exchanging the kind of inhibitory neurons and keeping all other network parameters fixed (see Table three).4. DISCUSSIONWe have constructed a spiking network model that captures elements from the architectonic organization of the cortex and of its composition in terms of cells of distinct electrophysiological classes. The architecture from the network is hierarchical and modular, which arguably (W.
