  • Values are mean gray values (±S.E.M.; arbitrary units) obtained from densitometric analysis of the medial, central and lateral thirds of the mid-striatum (0.5 mm anterior to bregma). Numbers in parentheses are the number of animals per group.

  • 2-a Significantly different from control, P < .05.

  • 2-b Significantly different from eticlopride alone, P < .05.
