Paper title: Psychosocial stress affects the acquisition of cerebellar-dependent sensorimotor adaptation.

•The specific role of the cerebellum in stress processing remains to be determined.•We examined how stress modulated cerebellar-dependent saccadic adaptation.•Psychosocial stress reduced the rate of saccadic adaptation.•Greater cortisol output was associated with slower adaptation.•These data demonstrate that stress modulates cerebellar-related functions.
