After a stroke, a patient exhibits muscle weakness due to reduced neural signaling. Which mechanism explains why synaptic potentiation therapy might improve motor function?

💡 Explanation

Synaptic potentiation enhances neural signaling after a stroke because it increases the sensitivity of postsynaptic receptors to neurotransmitters. This improves signal transmission across weakened synapses, therefore strengthening neural pathways. It does this rather than affecting glial cells or action potential propagation.
