These data demonstrate a chain of synaptically connected neurons extending to the rat kidney through several levels of the neuraxis from the forebrain, and the lamina terminalis - an area known to be involved in the regulation of body fluid homeostasis. The Bartha strain of pseudorabies virus was injected into the kidney of male Sprague-Dawley rats, resulting in retrograde infections in spinal cord segments (T1-T8), and successive infection in five autonomic 'premotor' areas of the brain, the rostroventrolateral medulla, rostroventromedial medulla, raphe nuclei, A5 region of the pons, and the paraventricular nucleus of the hypothalamus, as well as the nucleus of the solitary tract, locus coeruleus, and subcoeruleus nuclei. Higher order labelling was found in regions of the forebrain, including the organum vasculosum of the lamina terminalis, median preoptic nucleus, subfornical organ, medial preoptic area, bed nucleus of the stria terminalis, anteroventral periventricular nucleus, lateral preoptic area, suprachiasmatic nucleus, retrochiasmatic nucleus, primary motor cortex, and visceral cortex. This polysynaptic pathway to the kidney may form the substrate underlying the impact of forebrain structures on renal function. Copyright (C) 1999 Elsevier Science B.V.
