This period of synaptic "blooming" is followed by a period of sharp decline. This is, there is a "pruning" of synapses that occur based upon the activity of the brain. This is called experience-expectant learning (Cziko, 2000)

Greenough and Black (16) have proposed two mechanisms by which new synapses result from experience. In the first, which they term experience-expectant synaptogenesis, synapses form after minimal experience; the prototype is the development of stereoscopy.

There is evidence that, subsequent to this early developmental process of experience-expectant synapse selection, “experience-dependent” synaptogenesis, in which experience seems to drive the formation of synapses, occurs (1). One classical example of this process is seen in rats reared after weaning in a complex,
