Facilitatory effect of the dopamine D4 receptor agonist PD168,077 on memory consolidation of an inhibitory avoidance learned response in C57BL/6J mice

The still unknown contribution of the D4 receptors to memory consolidation was studied examining the memory effects of the dopamine D4 agonist PD168,077, the putative dopamine D4 antagonist L745,870, their mutual combination, and the combination of the D4 agonist with representative compounds acting as agonist or antagonist on the D1, D2 and the D3 receptors. Memory consolidation was assessed in C57BL/6J mice using the one-trial step-through...
