Activity of ADX71743 and olanzapine in the DOI-induced head twitches test in mice together with the measured plasma, CSF concentrations and CSF concentration/IC50 (in vitro) of ADX71743 in mice at the end of the experiment

CSF exposure was calculated from the plasma exposure using mice plasma protein binding (fu = 4.4%).
