Normal is also used to describe individual behavior that conforms to the most common behavior in society (known as conformity).However, normal behavior is often only recognized in contrast to abnormality. Synaptic pruning. the process where by unused synapses fade away while the relationship between synapses of neurons that communicate frequently are strengthened thus increasing functionality, the process whereby neural networks are formed is called neuroplasticity; neurons transmit information by sending messages through the synapses (space between neurons) which increases gray matter and funcionality, aim: to see whether learning a new skill (juggling) would have an effect on the brain, the increase in gray matter demonstrates neuroplasticity via dendritic branching as neural networks were increasing functionality; the reduce back to normal demonstrates synaptic pruning as the neural networks were no longer being used. The Organization of the Mature Brain. Impulses from one presynaptic nerve fiber may end on postsynaptic region of large number neurons and this is called as divergence. Synaptic pruning has been viewed as a learning mechanism, where the “pruning” or removal of a synapse is dependent on the neurons’ responses to environmental factors and external stimuli (Craika & Bialystokb, 2006). :) HOW DOES THE PROCESS OF MYELINATION AND SYNAPTIC PRUNING AFFECT NEURAL PROCESSING?
