Neural basis of self : ウィキペディア英語版 | Neural basis of self The neural basis of self is the idea of using modern concepts of neuroscience to describe and understand the biological processes that underlie human's perception of self-understanding. The neural basis of self is closely related to the psychology of self with a deeper foundation in neurobiology. ==Experimental techniques== In order to understand how the human mind makes the human perception of self, there are different experimental techniques. One of the more common methods of determining brain areas that pertain to different mental processes is by using Functional Magnetic Resonance Imaging. fMRI data is often used to determine activation levels in portions of the brain. fMRI measures blood flow in the brain. Areas with higher blood flow as shown on fMRI scans are said to be activated. This is due to the assumption that portions of the brain receiving increased blood flow are being used more heavily during the moment of scanning.〔About Functional MRI. http://www.fmri.org/fmri.htm.
