Nicotine Craving Clinical Trial
Official title:
Effect of Trigeminal Nerve Stimulation (TNS) on Nicotine Craving: Phase II, Cross-over, Randomized, Sham-controlled Clinical Trial
Electrical stimulation provides direct modulatory effects on subcortical regions. Indeed, neuroimaging studies show changes in neural activity in specific brain regions such as the amygdala, insula, precentral gyrus, hippocampus and thalamus. The neuroanatomical connections established with the trigeminal nerve have been associated with the mechanism called "bottom-up" neuromodulation. According to this hypothesis, the spread of electrical stimulation follows a path from the peripheral nerves towards the brain stem was then advertise for cortical and subcortical regions. Connections to structures involved in the reward system as the amygdala and hippocampus could theoretically modulate dysfunctional brain activity in these regions, which may induce favorable clinical effects.
