The end of the 20th century became a milestone for the progress of Neurosciences and their contribution to a better understanding of the physiological mechanisms involved in cognition, mood and human behavior. Because of this, it was possible not only to intervene some of the aforementioned aspects with therapeutic purposes, but more recently they became objects of study in researches with a more pragmatic nature, such as clinical researches involving persons with no mental or physical disorders, but who require to (...) prove remarkable abilities for executive functions, e.g., soldiers, pilots, students, among others. On the other hand, there is an ethical and scientific debate over the interest to evaluate certain psychotropic medications due to its possible sideeffects as cognitive enhancers in healthy subjects that, because of their social status, might be benefited in their social, academic or work life by developing a better mental performance. Therefore, the article aims to present from the perspective of Bioethics and Psychopharmacology some aspects of the research in Neurosciences that might throw light upon the scientific debate oriented towards the social significance of such clinical studies and their possible consequences for the future.
