The gradual pruning of the initially blurry axonal branching occurs via competitive and facilitative mechanisms relying on electrical activity at the synapses: axons that fire independently of each other tend to compete for territory whereas axons that synchronously fire mutually amplify connections.
A poda gradual da ramificación axonal borrosa inicial prodúcese por medio de mecanismos competitivos e facilitativos que dependen da actividade eléctrica nas sinapses: os axóns que disparan impulsos independentemente un do outro tenden a competir polo territorio, mentres que os axóns que de forma sincrónica disparan mutuamente amplifican as conexións.
