AUTHOR=Silva-dos-Santos Amílcar TITLE=The Hypothesis of Connecting Two Spinal Cords as a Way of Sharing Information between Two Brains and Nervous Systems JOURNAL=Frontiers in Psychology VOLUME=Volume 8 - 2017 YEAR=2017 URL=https://www.frontiersin.org/journals/psychology/articles/10.3389/fpsyg.2017.00105 DOI=10.3389/fpsyg.2017.00105 ISSN=1664-1078 ABSTRACT=Direct communication between different nervous systems has been recently reported through Brain-to-Brain-Interfaces and brainet. Closed loops systems between a brain and the spinal cord from the same individual have also been demonstrated. However, the connection between different nervous systems through spinal cord has not yet been considered. This paper raises the hypothesis of connecting two spinal cords (spinal cord – spinal cord connection) as an indirect mean for communication of two brains and a direct way of communication between two nervous systems. A concept of electrical fingerprint of a drug is introduced. The notion of the connection between two parts of the same spinal cord to treat a paraplegic patient is also introduced. It is discussed possible applications of this technique to the fields of psychology, psychiatry and mental health. Also, it is discussed that external information injected to a spinal cord as well as spinal cord – spinal cord connection can become new tools to 1) study the physiology of the nervous system, 2) modeling specific behaviors, 3) study and modeling disease traits 4) treating neuropsychiatric disorders and 5) information sharing between two nervous systems.
