Caffeine can have both good and negative effects on our well-getting.
Having said that, our model can’t rule out the prospective confound that a lot more than a single element could be affecting the binding of raclopride. Also because raclopride binds to each D2R and D3R,51 we can’t distinguish no matter whether caffeine-induced increases in striatal BPND reflects only increases in D2R or also in D3R. Having said that, in putamen exactly where the relative density of D3R is considerably decrease than that of D2R,52 the effects of caffeine are likely to reflect D2R. Another confound in our research is the order effect as placebo was generally offered two h ahead of caffeine.
