    • For example, inhibitory synapses on the trunk dendrite would reduce interspine communication and could control saltatory conduction between spines (Shepherd and Brayton, 1987). - 2004, Gordon M. Shepherd, The Synaptic...
    • This effect is aimed at inducing large interspine intervals to accommodate a high number of voltage dependent Ca²⁺ channels. - 2004, Chris I. De Zeeuw, Federico Cicirata, Creating Coordination in the Cerebellum, page 54:
