Following a nerve injury, a rehabilitation program aims to restore function. Which mechanism explains why repetitive task practice enhances motor recovery in nervous system?

💡 Explanation

Repetitive task practice enhances motor recovery because it promotes Hebbian plasticity, specifically enhanced long-term potentiation (LTP) at synapses involved in the practiced movement. This strengthens the neural pathways. Therefore, LTP increases synaptic efficacy, rather than reducing glial cell activation, increasing inhibition, or decreasing neuronal excitability, which would hinder motor recovery.
