Vagus nerve stimulation modulates cocaine seeking induced synaptic plasticity in reward related brain circuits

Vagus nerve stimulation (VNS) has been shown to modulate cocaine-seeking behavior by reversing maladaptive neuroplasticity in key corticolimbic circuits. The study indicates that VNS enhances extinction learning and reduces the likelihood of relapse by normalizing synaptic changes induced by cocaine use. This research underscores the potential of VNS as a valuable adjunct treatment for addiction, particularly in enhancing the efficacy of behavioral therapies aimed at reducing drug-seeking behaviors.
