four) (Fig. 5), which provided each parameters, suggesting that both equally DA release and uptake alongside one another greatest demonstrate MOD results on [DA]max. On top of that, the greater AIC calculated just after omission of DA release when compared with DA uptake suggests the product omitting the DA release result is a poorer description of the information, which happens to be in step with the Investigation of path coefficients derived from your comprehensive model; this Moreover indicated that MOD principally increases DA release to enhance [DA]max.
