Effects of the 5-HT1A receptor agonists buspirone and 8-OH-DPAT on pupil size in common marmosets

As pupil size is affected by psychotropic drugs in all mammals, it has been used as a well-established clinical indicator for the preclinical and clinical development of novel drugs. It has been reported that activation of the serotonin (5-HT)1A receptor differently affects pupil response in rodents (mydriasis) and humans (miosis). Thus, it is important to establish a quantitative system for measuring pupil size using other species, such as...
