NOTES
1.Charles Darwin's theory aroused a lot of hot discussions and speculations a hundred years ago and later in the early 1990s；a growing number of anthropologists，psychologists and linguists readdressed the so call“hardest problem in science” with new methods.More information can be consulted in the book Language evolution edited by Christiansen，Morten H；Kirby，Simon（2003）.
2.The current view of delusions is that they are the result of biology gone awry.In contrast，the Golds argue that delusions are the result of both the misfiring neurons and the interaction between the brain and the social world.
3.More specific information can be consulted in the book Care and Development of the Human Senses：Rudolf Steiner's Work on the Significance of the Senses in Education by Willi Aeppli（2013）.
4.The information comes from the online book The Nervous System（http://www2.estrellamountain.edu/faculty/farabee/BIOBK/BioBookNERV.html）.The Online Biology Book is hosted by Estrella Mountain Community College，in sunny Avondale，Arizona.

6.The findings is addressed more specifically in an fMRI study（Ebisch et al.，2011a）.In this study，healthy participants watched videos depicting other individuals being touched on their hands in different ways and，at the end of the experiment，were touched on their hands themselves.
7.The Hypothesis explains why primates have such large brains，far larger than that of other beasts of a similar size，far larger than necessary for most of their day-today lives.More specific information can be found in Encyclopedia of the Sciences of Learning（2012）：2081-2082.
8.Jellema Tjeerd et al（2000）describes the response properties of several distinct but interrelated cell populations within the anterior part of the superior temporal sulcus（STSa），a high-level visual-processing area within the temporal cortex of the macaque monkey.The term STPa applies to the upper bank of STSa，which receives polysensory input.
9.Eleanor Maguire and her colleagues conducted a series of studies to examine whether different experiences can lead to specific changes in different brain areas since 2000.To examine whether these areas of the brain change in response to specific experiences，Maguire and her colleagues（2000）recruited a sample of London taxi cabdrivers.This sample was chosen because driving in London is a complex task and taxi drivers have to go through several years of training prior to receiving their licence.
10.The map shows the WordNet tree projected into the shared semantic space.Projections of each object or action onto shared semantic PCs 2，3 and 4 are shown in red，green and blue，respectively.More information can be found at the web-site：http://gallantlab.org/publications/huth-et-al-2012.html
