A) NAc recording site. Brain slices from α6L9’S and nonTg mice were prepared at the indicated coordinates. Carbon fiber electrode and stimulating electrode were placed approximately as indicated.
B) A representative cyclic voltammogram is shown from a recording of electrically-evoked DA release from NAc slices.
C) A representative plot of the peak oxidative (+0.6V) current versus time is shown for an evoked DA release event.
D) Input/output curve for DA release from nonTg and α6L9’S NAc slices. DA release from the indicated genotype was electrically evoked with a range of current values. The peak [DA]o data from each genotype were normalized, plotted, and fitted to an exponential function.
