“…The brushing stimulation analysis was restricted to the manually identified contralateral (left) insular cortex (blue). Note that the response is consistently located to the posterior insular cortex across all subjects, including GL, in line with our previous observations (Olausson et al, 2002(Olausson et al, , 2008. (red) and thigh (blue) soft brush stimulation from rest in the neuronopathy syndrome patient GL and six healthy subjects (S1-S6).…”

“…The tactile well-being of the body is of fundamental importance, not the least in primates, as illustrated in the classic study of infant monkeys displaying affection for a surrogate mother in response to tactile comfort (Harlow, 1958). In fact, we argue that the CT system provides an important sensory underpinning of social behavior and, moreover, plays an integral role in the foundation of self-awareness (McGlone et al, 2007;Olausson et al, 2008c;Craig, 2009).…”

“…In previous work, activations to different types of reward have been found that are somewhat consistent with those reported here, though not obtained in the same experimental runs in the same subjects as in Investigation 2. For example, the pleasantness of touch to the forearm which may be related to activity in CT afferent fibres (Olausson, 2008) Fig. 3 of Rolls et al, (2008b).…”

“…These unmyelinated afferents, present only in hairy skin, are sensitive to light stroking of the skin. First characterised in detail in 1993 by Vallbo, Olausson, Wessberg and Norsell from the Institute of Neuroscience and Physiology, Göteborg University, Sweden [19], and reviewed by this group in an upcoming issue of Neuroscience and Biobehavioural Reviews [13], these authors suggested that C-tactile fibres subserve an affective component of touch, engaging areas of the brain involved in the processing of emotion rather than those comprising the discriminative somatosensory system. Indeed, studies in two patients lacking large-fibre sensory axons yet preserved small-fibre function reveal that their capacity to feel this light touch remains.…”
