    Answer:

    When old  or degraded neurons are removed and replaced  in the brain cells   so that  extra synaptic connections and axons  are removed, while stabilizing the needed ones the process is called brain pruning.

    It ensures efficiency of synaptic connections.

    It occurs in childhood and adulthood, and its occurs to maintain  neuronal  networks  in the brain through reduction in number of synapses and neurons.

    Thus it is important in childhood to create new synaptic connections for the child’s brain during development   to   create new  pathways for  complex  synaptic transmission  needed for child developments.
