Affective Touch and the Neurophysiology of CT Afferents
CT afferents are receptors in mammalian hairy skin that fire action potentials when the skin is touched lightly which makes them particularly important in affective touch. Traditionally neuroscientific research has focused on more discriminative and

Preface
The term “somatosensory system” covers the wide array of specialized receptors, peripheral nerves, and central processing stages underlying the transduction and processing of somatosensory signals. Collectively, these are engaged in sensing, perceiving, and acting—upon stimulation of the body surface or during muscle activity. Cutaneous (skin) sensations are essentially multimodal and are classically described as the senses of touch, temperature, itch, and pain. Afferent types belonging to the class of small-diameter, unmyelinated C fibers have been implicated in each of these functions. Yet so far, the functional neurophysiology and contribution of non-nocicepti
