ABSTRACT
Age related changes in dopaminergic and serotonergic receptors were examined in Aplysia californica. In this study dopamine (DA) and serotonin (5-HT) receptor levels were examined for animals belonging to 4-, 5-, 6-, 8-, 9- and 12-month age groups. Receptors analysis was performed using radio-labeled d-[3H] lysergic acid diethylamide (LSD) as the specific ligand. Specific binding for 5-HT was found to be significantly greater than that for DA in the young (4-month post-hatch) animals. The total DA and 5-HT receptor levels changed significantly with age. Dopamine levels increased from 5.34 fmol/mg of protein at 4 months to 19.11 fmol/mg at 12 months. Serotonin receptor levels increased from 7.35 fmol/mg at 4 months to 20.45 at 12 months.
