Abstract
The effects of bilateral microinjections of mu-opioid receptor agonist DAMGO (0.00, 0.01, 0.1, or 1.0 mu g/side) were tested in rats for 120 min in activity monitors. The horizontal movement, rearing, and stere otypy times in seconds were measured during 12 consecutive 10-min time blocks. DAMGO (0.01, 0.1, and 1.0 mu g) resulted in biphasic effects, inhibition followed by activation for each of the three measures. The se data replicate the behavioral effects of ICV DAMGO except that the duration of the behavioral effects were longer with Acb injections.
