However, its clinical efficacy is not proven, and its mechanisms remain largely unknown. To compare the peripheral and central neural and behavioral effects in rats of GES with a pulse width currently used in clinical trials (GES\u2010A: 6 mA, 0.3 ms, 40 Hz, 2 s on, 3 s off) and GES with a wider pulse (GES\u2010B: same as GES\u2010A, except that the pulse width is 3 ms). Experiment 1: assessing gastric volume changes as a result of GES. Experiment 2: recording the extracellular potentials of a single neuron in the paraventricular nucleus (PVN) with GES. Experiment 3: determining the effects of GES on oxytocin\u2010immunoreactive (OT\u2010IR) neuron expression in the hypothalamus. Experiment 4: determining the effects of GES on food intake and body weight. GES\u2010B, but not GES\u2010A, significantly increased gastric volume. GES\u2010B activated a higher percentage of gastric distention\u2010responsive neurons in the PVN (93% vs. 81%,\n                    <jats:italic>P<\/jats:italic>\n                    = 0.021) and elicited more intensive neuronal responses than GES\u2010A. The number of OT\u2010IR neurons was significantly increased in the PVN and supraoptic nucleus with both methods of GES compared with control groups. The increase in OT\u2010IR neurons in the PVN was higher with GES\u2010B than with GES\u2010A. A 1\u2010week GES treatment significantly reduced daily food intake and body weight. GES\u2010B was more potent than GES\u2010A in producing weight loss (\n                    <jats:italic>P<\/jats:italic>\n                    &lt; 0.001). The effects of GES depend on the stimulation pulse width. GES with a wider pulse is more effective both peripherally and centrally and more potent in reducing body weight in rats.\n
