Cooperativity between extracellular adenosine 5'-triphosphate and activation of N-methyl-D-aspartate receptors in long-term potentiation induction in hippocampal CA1 neurons.

Neuroscience 113 , 617-628, (2002)

The mechanism of ATP-induced long-term potentiation (LTP) was studied pharmacologically using guinea-pig hippocampal slices. LTP, induced in CA1 neurons by 10 min application of 10 microM ATP, was blo...
