This detailed microcircuit model explores the network level effects of sublayer specific connectivity in the mouse CA1. The differences in strengths and numbers of synapses between PV+ basket cells and either superficial sublayer or deep sublayer pyramidal cells enables a routing of inhibition from superficial to deep pyramidal cells. At the network level of this model, the effects become quite prominent when one compares the effect on firing rates when either the deep or superficial pyramidal cells receive a selective increase in excitation.

// This code allows you to use default variables, where
// you have the option of either defining the variable
// at the command line when executing the code, or using
// the value defined in the code:
// $ ... nrniv -mpi -c myvariable=20 mymodelcode.hoc
// $ ... nrniv -mpi -c "strdef mystr" -c mystr="\"hello\"" mymodelcode.hoc
// code: default_var("myvariable",10)
// where the variable myvariable is only set in the code
// by using the default_var command

	s = new String()
	if (name_declared($s1) == 0) {	// If the name of the variable used
									//  at the command line has not yet
									//  been defined in the code
