Synaptic background activity was simulated in four reconstructed neurons from cat cerebral cortex, using several thousand glutamatergic and GABAergic inputs distributed in the soma and dendrites (see Experimental procedures; Destexhe and Paré, 1999). The same respective densities of synapses were used in all four cells. The table shows the parameters of the best fit of the point-conductance model using the same procedure. These parameters generally depended on the morphology, but their ratios were approximately constant (ge0/gi0 and σe/σi).
