Stabilization of dendritic spines. (a) Synaptic activity, including adhesive contact between pre- and postsynaptic compartments and trophic signaling between the two compartments, enhances dendritic spine stability. (b) Synaptic support maintains the integrity of dendritic architecture over time. The loss of this support results in destabilization of dendritic spines followed by dendritic simplification.
