Our brain could resemble a circuit: 80 billion neurons and perhaps a hundred trillion synapses are interconnected within a complex organ. One of the greatest challenges facing 21st century science is brain whole structures and functions disclosure. While emerging technology are spreading in every field, Europe suggested to associate neurobiological studies to technological knowledge and future improvements.
Brain and nerves
One of the most unknown places, still far from being explored and fully understood, is not (only) the deep universe: it is our brain. That is why USA and the European Union, in the very last years, started two separate, but parallel, initiatives to map the human brain. On March 2014, there has been a public announcement that the two projects will merge. Or will they smash?
The Human Brain Project
In this brief review I summarize some major findings demonstrating the specific anatomical and functional features of the brain of synaesthetes. There are several main findings of this research: (1) Brain areas, which are involved in controlling synaesthesia are anatomically different. (2) These brain areas are also differently activated during synaesthetic experiences. (3) There are not only anatomical and functional differences in those brain areas specifically involved.
