Gastric distention increases [14C]2-deoxyglucose uptake in the rat nucleus tractus solitarius

Stomach balloons were inflated with 20 ml of warm water in anesthetized rats who had a left cervical vagotomy. This increased [14C]2-deoxyglucose (2-DG) uptake in the commissural and medial portions of the right nucleus solitarius. This effect was not present in controls which received 2 ml of water in their stomach balloons.
