Change in monoaminergic extracellular concentration during MLR-evoked fictive locomotion. (A) Peak NE and 5-HT release during MLR-evoked fictive locomotion in DH, IZ/VH and adjacent WM (mean ± SEM). Note that NE release was significantly greater than 5-HT in the gray matter. (B) Comparison of peak monoamine concentrations observed with MLR evoked locomotion (loco) vs. no locomotion (bursting) in DH, IZ/VH and adjacent WM. Note that in the DH and IZ/VH, a significantly greater release of NE over baseline was observed in trials with locomotor activity. (C,D) Release of NE and 5-HT within the IZ/VH was significantly correlated to the time required to elicit locomotion with MLR stimulation. *p < 0.05, **p < 0.01.
