Question

Quizplus · Accepted Answer

The specificity of LTP to particular synapses on the postsynaptic neuron is likely due to the properties of dendritic spines. Dendritic spines are small protrusions on the dendrites of neurons that contain the glutamate receptors necessary for inducing LTP. The strength of the synapse is determined in part by the size and shape of the dendritic spine, which can change over time as a result of LTP or LTD. Therefore, the specific synapses that undergo LTP are likely those that have the appropriate dendritic spines to support the necessary changes in synaptic strength.
