Brain mapping or brain reading is possible now days with the advanced technology. The three principal methods used in dynamic brain imaging are,
• Functional magnetic resonance imager (fMRI) technology
• Positron emission tomography (PET)
• Optical tomography
By using these techniques, one can map the activities (activation levels) in some particular brain areas with the person’s emotions.
Thus, the blanks can be filled with fMRI; PET; optical tomography.
