- two competing theories of dopaminergic motivation
- 26 PD patients ON and OFF dopaminergic medication
- This measures how much faster each saccade is than the speed predicted from its amplitude
- Thus, positive (negative) residuals mean a particular saccade was faster (slower) than predicted by the main sequence
- We found no correlation between effects of contingent and guaranteed rewards on peak saccade velocity residuals in PD ON, PD OFF or HC separately, nor a correlation between medication states
