Table 1. Growth curves for synaptic elements.

	Post-synaptic elements
	Excitatory			Inhibitory
	(ϵ = ψ)	(η < ψ < ϵ)	(ψ = η)	(ϵ = ψ)	(η < ψ < ϵ)	(ψ = η)
Normal Repair	Yes	No	Yes	Yes	No	Yes
	Yes	NA	No	No	NA	Yes
	Pre-synaptic elements
	Excitatory			Inhibitory
	(ϵ = ψ)	(η < ψ < ϵ)	(ψ = η)	(ϵ = ψ)	(η < ψ < ϵ)	(ψ = η)
Normal Repair	Yes	No	Yes	Yes	No	Yes
	No	NA	Yes	Yes	NA	No

Only the derived families of pre- and post-synaptic growth curves allowed for both: (a) stable function of network in the absence of any deafferentation; (b) restoration of activity to the LPZ by an inward propagation of excitatory connections and an outward growth of inhibitory projections. (NA = Not applicable: since these regimes did not maintain a normal (without deafferentation) network in its balanced state, they were not tested for successful repair.)
