Excerpt from Nerve Control and How to Gain It Selection, expansion, and rearrangement have been made with reference particularly to the prevention, as well as the cure, of the functional nervous troubles so common to day. No book, it should be clearly under stood, can be of more than incidental help to the victim of an organic nervous disease. His chief reliance must always be on the skill of his physician. So, too, as is repeat edly insisted in subsequent -pages, many functionally nervous patients are so condi tioned that expert treatment of a special kind is imperatively needed by them. But of functional nervousness in general it may be said with assurance that much can be done in the way of self-cure. It is mainly a question of learning to think healthfully and learning to live healthfully. The nervous dyspeptic, the nervous insomniac, all the great army of the nervously run down, are essentially Victims of wrong modes of thinking and living. If they can be induced to think and live aright, their ills fall from them. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

The kidney is innervated with efferent sympathetic nerve fibers reaching the renal vasculature, the tubules, the juxtaglomerular granular cells, and the renal pelvic wall. The renal sensory nerves are mainly found in the renal pelvic wall. Increases in efferent renal sympathetic nerve activity reduce renal blood flow and urinary sodium excretion by activation of α1-adrenoceptors and increase renin secretion rate by activation of β1-adrenoceptors. In response to normal physiological stimulation, changes in efferent renal sympathetic nerve activity contribute importantly to homeostatic regulation of sodium and water balance. The renal mechanosensory nerves are activated by stretch of the renal pelvic tissue produced by increases in renal pelvic tissue of a magnitude that may occur during increased urine flow rate. Activation of the sensory nerves elicits an inhibitory renorenal reflex response consisting of decreases in efferent renal sympathetic nerve activity leading to natriuresis. Increasing efferent sympathetic nerve activity increases afferent renal nerve activity which, in turn, decreases efferent renal sympathetic nerve activity by activation of the renorenal reflexes. Thus, activation of the afferent renal nerves buffers changes in efferent renal sympathetic nerve activity in the overall goal of maintaining sodium balance. In pathological conditions of sodium retention, impairment of the inhibitory renorenal reflexes contributes to an inappropriately increased efferent renal sympathetic nerve activity in the presence of sodium retention. In states of renal disease or injury, there is a shift from inhibitory to excitatory reflexes originating in the kidney. Studies in essential hypertensive patients have shown that renal denervation results in long-term reduction in arterial pressure, suggesting an important role for the efferent and afferent renal nerves in hypertension.

A practical guide to working with the principles of polyvagal theory beyond the therapy session. Deb Dana is the foremost translator of polyvagal theory into clinical practice. Here, in her third book on this groundbreaking theory, she provides therapists with a grab bag of polyvagal-informed exercises for their clients, to use both within and between sessions. These exercises offer readily understandable explanations of the ways the autonomic nervous system directs daily living. They use the principles of polyvagal theory to guide clients to safely connect to their autonomic responses and navigate daily experiences in new ways. The exercises are designed to be introduced over time in a variety of clinical sessions with accompanying exercises appropriate for use by clients between sessions to enhance the therapeutic change process. Essential reading for any therapist who wants to take their polyvagal knowledge to the next level and is looking for easy ways to deliver polyvagal solutions with their clients.
