Touch again is an excellent source for such investigation. Our tactual experiences often seem to have a felt pleasant or unpleasant character. This isn’t simply an associated but distinct state of pleasure or pain that accompanies the perceptual experience, but part of the perceptual experience itself. Paradigm examples include the pleasure derived from delicious food or the awfulness of certain bad smells. Here again, touch is ready for increased investigation. In recent years, researchers have discovered a specialized class of afferent nerve channels that seem to be responsible for the experience of pleasantness (Löken et al. 2009; McGlone et al. 2012). These channels, called CT-Afferents, are maximally responsive to slow, regular activations like those generated by a feather pulled gently across the arm. These channels seem like pleasant versions of the famous C-fibers implicated in pain experiences.
