Book Description
This volume represents the Proceedings of the Second Inter national Symposium on Skin Senses held on the campus of Florida State University, Tallahassee, Florida. The symposium was held on June 5 through 7, 1978, in honor of Professor Yngve Zotterrnan to commemorate his 80th birthday and his more than 50 years of energetic involvement in physiological and psychophysical prob lems of cutaneous, gustatory, and olfactory sensitivities. The First International Symposium on Skin Senses was in tended to stimulate dialogues between electrophysiologists and psychophysicists in order to examine the mechanisms of cutaneous sensitivity by way of a mUlti-disciplinary approach. The 12 years since that meeting has seen much progress in the morphology, electrophysiology, and taxonomy of cutaneous receptors. There has been a growing awareness among psychophysicists that, not only are psychometric threshold functions of importance, but descriptions of the growth of sensations to suprathreshold stimuli are of at least equal importance. One of the most exciting recent events has been the development of a technique that permits recording activity in single primary afferent nerve fibers by poking a microelectrode through the skin into a nerve bundle--microneurography. This development allows one to conduct psychophysical measurements of sensation and, at the same time, to sample the primary neural activity associated with the same stimuli. The aim of this symposium was to bring to gether psychophysicists and microneurographers in order to explore the power and the limitations of such an approach when applied to the cutaneous senses.

Book Description
Sensory Functions of the Skin in Primates: With Special Reference to Man deals with sensory functions of the skin in primates, particularly humans. The discussions are organized around three themes: mechanoreception, thermoception, and nociception. Comprised of 43 chapters, this volume begins with a detailed treatment of the natural and paranatural stimulation of sensory receptors, followed by an analysis of a theory of sympathetic-sensory coupling. The reader is then introduced to the "receptripse", the desmosome-like lamellar-axonal junction subserving mechano-electric transduction and inducing the sympathetic actions on the pacinian sensor. Subsequent chapters focus on differences in timing of corticocuneate and corticogracile actions; organization and neuronal morphology of the spinocervical tract; skin mechanoreceptors in the human hand; and cellular mechanisms in the parietal cortex in alert monkeys. The book also examines the response of central trigeminal neurons to cutaneous thermal stimulation and the role of thermoreceptors in thermoregulation. This monograph will be of interest to specialists in fields ranging from anatomy and biology to physiology and neurophysiology.

Book Description
The skin, the body’s largest organ, is strategically located at the interface with the external environment where it detects, integrates and responds to a diverse range of stressors, including solar radiation. It has already been established that the skin is an important peripheral neuroendocrine-immune organ that is closely networked with central regulatory systems. These capabilities contribute to the maintenance of peripheral homeostasis. Specifically, epidermal and dermal cells produce and respond to classical stress neurotransmitters, neuropeptides and hormones, production which is stimulated by ultraviolet radiation (UVR), biological factors (infectious and non-infectious) and other physical and chemical agents. Examples of local biologically active products are cytokines, biogenic amines (catecholamines, histamine, serotonin and N-acetyl-serotonin), melatonin, acetylocholine, neuropeptides including pituitary (proopiomelanocortin-derived ACTH, b-endorphin or MSH peptides, thyroid stimulating hormone) and hypothalamic (corticotropin-releasing factor and related urocortins, thyroid-releasing hormone) hormones, as well as enkephalins and dynorphins, thyroid hormones, steroids (glucocorticoids, mineralocorticoids, sex hormones, 7-δ steroids), secosteroids, opioids and endocannabinoids. The production of these molecules is hierarchical, organized along the algorithms of classical neuroendocrine axes such as the hypothalamic pituitary adrenal axis (HPA), hypothalamic-thyroid axis (HPT), serotoninergic, melatoninergic, catecholaminergic, cholinergic, steroid/secosteroidogenic, opioid and endocannabinoid systems. Disruptions of these axes or of communication between them may lead to skin and/or systemic diseases. These local neuroendocrine networks also serve to limit the effect of noxious environmental agents to preserve local and consequently global homeostasis. Moreover, the skin-derived factors/systems can also activate cutaneous nerve endings to alert the brain to changes in the epidermal or dermal environments, or alternatively to activate other coordinating centers by direct (spinal cord) neurotransmission without brain involvement. Furthermore, rapid and reciprocal communications between epidermal and dermal and adnexal compartments are also mediated by neurotransmission including antidromic modes of conduction. Lastly, skin cells and the skin as an organ coordinate and/or regulate not only peripheral but also global homeostasis.
