WebNational Center for Biotechnology Information Homosynaptic plasticity is one type of synaptic plasticity. Homosynaptic plasticity is input-specific, meaning changes in synapse strength occur only at post-synaptic targets specifically stimulated by a pre-synaptic target. Therefore, the spread of the signal from the pre-synaptic cell is localized. Another type of synaptic plasticity, heterosynaptic plasticity, is not input-specifi…
