Inhibition by ATP of fEPSP recordings in hippocampal slices from CD73^+/+ and CD73^−/− mice.

<p>(a) Representative traces of fEPSPs; numbers 1–6 correspond to before and during superfusion of slices with ATP (10, 25, 50 or 100 µM) or ATP (100 µM) and DPCPX (1 µM) as indicated in (b). (b) The effect of ATP on fEPSP slope in hippocampal slices from CD73^+/+ and CD73^−/− mice. Horizontal lines represent the duration of superfusion with the indicated ATP concentrations. (c) Maximum inhibition of fEPSPs obtained with each concentration of ATP. <i>n</i> = 4 CD73^+/+ and 5 CD73^−/−.
