Chemelli et al (1999) examined fos-reactivity in orexin neurons of mice provided modafinil prior to sacrifice and found a considerably larger activation of orexin neurons with modafinil than with placebo.
They also observed that the dopamine autoreceptor agonist quinpirole attenuated the results of modafinil in DSP-four handled mice, indicating a role for dopamine in modafinil’s wake-promoting results.

Far more nigral neurons survived when modafinil was administered along side MPTP. They concluded that modafinil stimulates locomotor consequences in by now hurt animals, and modafinil is neuroprotective, but it does not efficiently block the DA transporter, for it really is not able to avoid the Preliminary results of MPTP which enters the mobile throughout the dopamine transporter to lead to hurt.
Edgar and Seidel (1997) investigated the consequences of modafinil on rest-wake EEG and locomotor exercise in Are living rats compared with the results of methamphetamine. They observed that modafinil amplified locomotor exercise only a bit compared with methamphetamine which induced profound improves in locomotor exercise.
