^*Relationships between behavioral variables and indices of dopaminergic function.

r= Pearson product moment correlations, P= Significance levels, N=number of mice in each correlation. Bold P values indicate significant correlations. Note that 5 mice were eliminated prior to determining DA half-life at baseline due to electrode failure and 4 animals were eliminated from the pre/post nomifensine analysis of DA half-life due to failure to respond to the nomifensine injection.
