    Behavioural and physiological stress-induced changes observed in alpha9-nAChR KO mice demonstrate a novel role of the alpha9alpha10-nAChR in mounting a normal stress response. The lack of functioning alpha9alpha10-nAChRs leads to negative affective changes after a relatively short period of stress. KO mice exhibited unusual patterns of circadian activity and a dysfunction in reward seeking after a period of reduced acc...

    α9-nAChR knockout mice exhibit dysregulation of stress responses, affect and reward-related behaviour.
