| Research Abstract |
In conclusion, we have found that morphine may induce cell-dependent dual modulation of glutamatergic synaptic transmission in the habenular nucleus. Moreover, it is our conclusion that morphine, fentanyl and oxycodone each produce the mu-opioid receptor-independent suppression of sodium currents by distinct mechanisms in thalamic neurons.
