摘要

Increasing number of evidence support the role of ventral tegmental area (VTA) and nucleus accumbens (NAc) in mediating the opiate effects as the two critical components of brain reward pathway. It is believed that VTA to NAC dopaminergic projections mediate the reinforcing effects induced by opioid drugs. Although numerous studies have investigated mechanisms of reward processing in these brain regions, alterations of local field potentials (LFPs), as an index of total synaptic currents, has not been previously addressed.
