Pruning of those that were not used in the process.
Explanation:
LTP (long-term potentiation) may be defined as the strengthening of the synapse that are mainly based on the recent pattern activity. They are mainly based on the synaptic activity.
This LTP also denotes the phenomena of the synaptic plasticity. Dedndritic spines shows the LTP. The binding of the cleft occurs at the synaptoc end and the transfer of the receptor strength increases. Different spines amy form during the LTP. The pruning do not occur even if they are not in use.
