Detection of spontaneous, transient adenosine release <i>in vivo</i>.

<p>(A) <i>In vivo</i> spontaneous, transient adenosine release. The current vs. time plot has two traces, an orange line at 1.4 V for the primary oxidation and a black line at 1.2 V for the secondary oxidation. The dashed lines on the color plot and current vs. time plots indicate where CVs were taken. (B) Cyclic voltammograms of adenosine over time. The top (1^st) is when adenosine first appears, the middle CV (2^nd) is half a second later when the primary peak is at a maximum and the bottom (3^rd) is half a second later when the secondary peak is at its maximum. The ratio of the primary and secondary oxidation peaks can change over time.
