Stimulation of the celiac ganglion would activate the sympathetic nervous system, which generally leads to the mobilization of energy reserves in the body, including the breakdown of glycogen in the liver to release glucose into the bloodstream. This is part of the body's "fight or flight" response to stress, and helps to provide extra energy to the muscles and other organs during times of heightened activity or stress. Therefore, stimulation of the celiac ganglion would likely lead to a decrease in glycogen reserves in the liver.
