The cerebellum
-
The cerebellum is increasingly recognized to contribute to non-motor functions, including cognition and emotion. Although fear conditioning has been studied for elucidating the pathophysiology of anxiety, the putative role of the cerebellum is still unknown. Fear conditioning could also be important in the etiology of chronic abdominal pain which often overlaps with anxiety. ⋯ Neural correlates of reinstatement were found in Crus I, Crus II, IV, V, and IX. We could show for the first time that the cerebellum is involved in abdominal pain-related associative learning processes. Together, these findings contribute to our understanding of the cerebellum in aversive learning and memory processes relevant to the pathophysiology of chronic abdominal pain.
