If some of the synapses onto a cell have been highly active and others have not, only the active ones become strengthened. This is known as the property of specificity.
Synapse allows the neuron to pass electrical and chemical signals to other neuron. A specificity of synaptic connection between neurons and target cells is known as synaptic specificity.
