The conclusions drawn from this study are brainwaves associated with cognitive-language, sensorimotor and auditory-visual functions are represented in both hemispheres and they are efficiently integrated via commissure systems, resulting in one hemispheric specialization. For auditory-visual brainwave responses, bilateral activities were again observed, but their lateralization was mild and could be in any hemisphere. The sensorimotor responses also showed bilateral hemispheric responses, but stronger in the contralateral hemisphere to the induced sensation or movements. The results disclosed silent word and picture naming were bilaterally represented, but stronger responses were in the left frontal lobe and in the right parieto-temporal lobes respectively. Data were further analysed using matrix laboratory method for bilateral hemispheric activity and specialization. Topographical, equivalent current dipoles and spectral analysis for somatosensory, motor, auditory, visual and language evoked magnetic fields were performed. The brainwaves of thirteen clinical patients were analysed. Besides exploring deep anatomical areas of the brain, superficial cortical areas were also studied. These special features have made it as a possible site for seat of human soul and form a crucial part in discussion related to death. Presence of buoyancy also causes major flexure to occur at midbrain level and this deep bending area of the brain, better known as greater limbic system seems to regulate brain functions and site for cortical brainwave origin. This indicates central nervous system always need microgravity environment to function optimally. This buoyancy environment seems to have been existing since embryogenesis. Central nervous system seems to float inside a craniospinal space despite having miniscule amount of CSF.
