Abstract
Methods and devices are provided for influencing an amount of food ingested. The methods include applying stochastic resonance stimulation to a stomach to influence a nervous system response using an implantable stimulation device. In one embodiment, a device includes electrodes in communication with a gastric wall capable of delivering stimulation therapy, and a controller adapted to apply stochastic resonance stimulation to a stomach to influence a response of stomach receptors and/or interstitial cells of Cajal. In some embodiments, the implantable device is configured to apply a suprathreshold signal in addition to the stochastic resonance stimulation. In some embodiments, the implantable device is configured to apply an electrical signal in other areas of the nervous system besides the stomach. In some embodiments, the implantable stimulation device is an implantable cardiac stimulation device capable of providing therapy to a heart.
