Antidepressant effect of chronic ethanol in adult rats

Increased dopamine (DA) and noradrenaline (NA) metabolites in whole brain as well as increased DA release in slices of caudate nucleus from ethanol dependent rats have been previously found. It is known that both DA and NA are present in caudate (CAU) and accumbens (ACC) nuclei. In view of this, pos...
