[Abstract] Topological representation is undertaken for the function of mind. Klein\u27s bottle so modified as to have the point cross section of infinite area at the intersection of different parts of its own surface is considered as the simplest model of elementary topological structure of mind. Brain may be the manifestation of the multiple combination of such singular elementary structures. Mind is considered to be the excitation of one combination and change of mind is then the transfer of excitation to other combination of those singular elementary structures
