The present disclosure describes methods for treating diseases and conditions of the central and peripheral nervous system by stimulating or increasing neurogenesis. The hinge assembly includes a hinge pin and a hinge stay. The preferred embodiment of the rechargeable transponder uses a piezoelectric battery that is to be implanted in an appropriate manner that would permit a large muscle to act upon a piezoelectric element thereby converting the mechanical energy into electrical energy to provide a recharge to the battery. The image data is color and intensity corrected based on a scaled reference object. The adjusting signal is applied to the converter via the output port and is operative to adjust a subsequent common-mode voltage level of the differential signal. The at least one projection and at least one opening have configurations that corresponding to at least one feature of the drug.
