Characterization of thalamic neuronal responses to urinary bladder distention, including the effect of acute spinal lesions in the rat.

Unlabelled: Chronic visceral pain has proved to be difficult to treat. This study characterized urinary bladder distention (UBD)-evoked responses of neurons located within the ventrobasal group of the thalamus. Units were also characterized for responses to cutaneous stimuli and colorectal distention (CRD).
