Table 1. Genotype X Age X Stress Interactions Following Manipulation of Presynaptic Dopamine Neurons.

Sexually immature and mature males and females were assayed for heart rate and locomotion following a 24 hour exposure to starvation or oxidative stress. Exploratory and basal locomotion refer to the first 2 and last 5 minutes of a 15 minute period, respectively.

Mean for walking, stopped, and highly mobile is a calculation of the mean duration of each bout. n = 40 individuals for each population (for heart rate) and n = 45 individuals for each population (for locomotion). 3-way ANOVA (Genotype X Sex X Stress),

^*p < 0.05,

^**p < 0.01,

^***p < 0.001.
