Methods and systems described herein can be used to automatically turn on and off stimulation of a target dorsal root ganglion (DRG) and/or adjust stimulation parameters. At least one of an input signal (indicative of an electrical field resulting from an electrical signal propagated by adjacent distal sensory nerve fibers toward the target DRG), an output signal (indicative of an electrical field resulting from an electrical signal propagated by adjacent proximal sensory nerve fibers away from the target DRG) or a DRG signal (indicative of an electrical field produced by cell bodies of primary sensory neurons within the target DRG and resulting from an electrical signal propagated by sensory nerve fibers within the target DRG) is/are obtained and analyzed. Delivery of electrical stimulation is turned on and off and/or at least one of pulse amplitude, pulse width and/or pulse repetition rate is/are adjusted based on results of the analysis.

Methods and devices are provided for activating brown adipose tissue (BAT). Generally, the methods and devices can activate BAT to increase thermogenesis, e.g., increase heat production in the patient, which over time can lead to weight loss. In one embodiment, a medical device is provided that activates BAT by electrically stimulating nerves that activate the BAT and/or electrically stimulating brown adipocytes directly, thereby increasing thermogenesis in the BAT and inducing weight loss through energy expenditure.

A device for providing transdermal electrical stimulation at an adjustable position on a head. The device including a supporting member economically shaped and configured to be fixedly supported about an anatomical body part; the supporting member being adjustably positionable in only two directions substantially perpendicular to one another. No electrical stimulation is provided by the supporting member. Alternatively, the device includes at least one pair of electrodes for producing the transdermal electrical stimulation to the head. The electrodes are mounted to a securing member shaped and configured to be releasably securable only about a plurality of strands of hair at a predetermined fixed orientation without being secured about any anatomical body part.
