Mental Imagery of Representation beyond the Equivalence of Perception by Emphasizing Methods FMRI

Introduction: Knowledge representation includes different methods through which our mind creates mental structures, the representation of what we know about the world out of our mind. In mental imagery, we create similar mental structures which represent the things which our sensory organs haven’t sensed. Some studies relating to the blind subjects and some applied studies on rehabilitation have highlighted the importance of mental imagery for the cognitive psychologists. Aim of this study is to investigate the mental imagery with FMRI studies on neural structures in common tasks with the normal consciousness range for comparison of neural functional equivalence beyond the neural perception level. Methods and Material: The research was conducted with key words of mental imagery, representation, FMRI in pubmed, google Scholar and Science direct databases and SID database, without time limitation and in both Persian and English languages. Results: 70 original research papers were obtained among which 5 papers were reviewed finally after the evaluation of scientific validity for responding to the research questions. Analysis of the final papers showed that knowledge representation through mental imagery was beyond the perceptional neural functional equivalent. Conclusion: Common neural bases can be searched by designing specific tests in different consciousness levels such as hypnotism, mental imagery, and normal awareness and with FMRI expanding functions
