Cortical plasticity as synaptic mechanism for chronic pain

Adult brain structures such as the hippocampus are highly plastic to learning and gaining new experiences. Recent studies reveal that cortical areas that respond to sensory noxious stimuli (stimuli that cause pain in humans) are also highly plastic, like the learning-related hippocampus. Long-term potentiation (LTP), a key cellular model for learning and memory, is reported in the anterior cingulate cortex (ACC) and insular cortex (IC), two key...
