The main challenge, however, is that the activation of this receptor can provoke hallucinations. Recent studies have shown that activating the receptor with certain (partial) agonists could potentially give rise to antidepressant effect without hallucinogenic side effects. Although substantial research has been done in this area, the atomistic details of this differential activation of the serotonin-2A receptor are not fully understood. In the present study we performed multiple atomistic molecular dynamics (MD) simulations on 5-HT\n                    <jats:sub>2A<\/jats:sub>\n                    R bound with two antipsychotics, three different potential non-hallucinogens and two hallucinogens to identify the receptor\u2019s ligand dependent conformations. Overall, our findings suggest that modest 5-HT\n                    <jats:sub>2A<\/jats:sub>\n                    R activation would only yield antidepressant effects and hallucinations result from excessive activation. While modest activation through microdosing may be problematic on account of abuse potential as well as possibly narrow and patient-dependent therapeutic windows, modest activation through administration of a sufficiently weak partial agonist may offer a viable drug development pathway.\n
