The aim of the Scholarpedia Encyclopedia of Touch is to provide a comprehensive set of articles, written by leading researchers and peer-reviewed by fellow scientists, detailing the current scientific understanding of tactile sensing and its neural substrates in animals including man. It is hoped that the encyclopedia will encourage sharing of ideas and insights between researchers working on different aspects of touch and in different species, including research in synthetic touch systems. In addition it is hoped that the encyclopedia will raise awareness of research in tactile sensing and promote increased scientific and public interest in the field. The Encyclopedia of Touch was part-sponsored by the European Union Framework 7 BIOTACT project (2008-2012), one of whose goals was to promote research in the fields of natural and synthetic tactile sensing. The encyclopedia is open to new contributions on any topic related to touch sensing in animals or artefacts.
Scope and Structure
The encyclopedia is structured in three sections:
- Haptics and cutaneous touch: In primates and humans tactile sensing is primarily through the skin and particularly on sensory surfaces such as the fingertips and the lips where there is a high density of touch receptors.
- Vibrissal touch: The tactile senses of many mammals are built around arrays of facial hairs known as whiskers or vibrissae. Research on vibrissal touch has focused on rodents and, in particular, on rats and mice. The vibrissal system in rodents is interesting in its own right but has also become an important model system in which to investigate and understanding mammalian sensory processing more generally.
- Comparative touch: There are a large number of specialist tactile sensory organs in the animal kingdom. This section will contain articles on animal species that exhibit interesting or exceptional tactile sensing abilities.
The Encyclopedia went online in February 2008 and was substantially revised and extended December 2014 to March 2015. Presently contributions to the Encyclopedia are by invitation from the editors but we are open to suggestions of new article from authors with relevant expertise.
