How does morphology relate to function in sensory arbors?

abstract：:In the classical picture of brain function, electrical impulses are initiated in sensory organs and spread rapidly down axons, jumping synaptic clefts by neurochemical transmission. Patterns of electrical activity generated in this way integrate information throughout the brain and result in coordinated motor output. ...
