The action of the dopaminergic agonist, piribedil, on a conditioned avoidance response was studied in normoxic or hypobaric hypoxic rats. This agonist has no effects in normoxia, but induced an anti-hypoxic protection (improvement of learning in hypoxia), antagonised by low doses of pimozide. The mechanism of the anti-...
