<P> 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 . </P> <P> 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 . Positron emission tomography is another method used to study brain activity . </P> <P> Two areas of the brain that are important in retrieving self - knowledge are the medial prefrontal cortex and the medial posterior parietal cortex . The posterior cingulate cortex, the anterior cingulate cortex, and medial prefrontal cortex are thought to combine to provide humans with the ability to self - reflect . The insular cortex is also thought to be involved in the process of self - reference . </P> <P> The sense of embodiment is critical to a person's conception of self . Embodiment is the understanding of the physical body and its relation to oneself . The study of human embodiment currently has a large impact on the study of human cognition as a whole . The current study of embodiment suggests that sensory input and experiences impact human's overall perception . This idea somewhat challenges previous ideas of human cognition because it challenges the idea of the human mind being innate . </P>
