Somatosensation is a topic of resurgent interest within the scientific study of consciousness. First, the neuroanatomical organization of the somatosensory system into different classes of receptors, afferent fibres, and cortical targets, offers a ready model for investigating concepts of sensory quality and modality. Second, several specific aspects of somatosensory experience offer important challenges for consciousness research. One of these is the puzzling nature of experience of somatosensory space, and this forms the focus of the present symposium. Somatosensory channels have poorer spatial acuity, and lower informational capacity than, say, the visual system. As a result, experience of somatosensory locations and extents is often impoverished or absent – leading some to propose that somatosensation is not a spatial sense at all. Further, many somatosensory systems (though not all) yield a conscious experience only when the skin contacts an object. This gives sparse sampling of the external world compared to other senses. In this symposium, we debate these and other problems in understanding somatosensory consciousness. Speakers from philosophy, psychology and neuroscience represent contrasting points of view on the experience of space though somatosensation. Importantly, our speakers also cover a range of somatosensory modalities, including touch, pain and proprioception. We also have a range of career stages represented. We anticipate useful contrast between views focusing on afferent signals from the body, and views focusing on centrally-generated, multisensory phenomenologies of object perception. We see this symposium as putting somatosensory space back where it belongs on the scientific map of consciousness.
