Abstract
- Compelling evidence has indicated the involvement of extracellular ATP and adenosine in the mechanisms of synaptic plasticity and memory formation. In the present study, adult rats were trained in a step-down inhibitory avoidance task (IA) or submitted to isolated foot-shock (IF) (0.4 mA) before measuring ectonucleotidase activities in the synaptosomes of the anterior and posterior cingulate cortex (AC and PC, respectively) and the medial precentral area (Fr2). IA increased ATP and ADP hydrolysis immediately after training in the synaptosomes of PC and AC, respectively, (P
