Electrophysiological recordings were used to investigate the effects of ATP analogues on [theta]-burst-induced long-term potentiation (LTP) in rat hippocampal slices. [alpha],[beta]-Methylene ATP ([alpha],[beta]-MeATP; 20 [mu]M) decreased LTP from 36±9% to 17±5%, an effect prevented by adenosine A1 receptor blockade in accordance with the localised catabolism of ATP analogues into adenosine, leading to adenosin...
