Based on the extensive quantum theory of biology and NeuroQuantology, the Schrödinger equation with the linear potential may become the Bessel equation. Its solutions are Bessel functions, and may form the double helical structure of DNA in three dimensional spaces. From this model we may predict the discrete bound energy spectrum of DNA. Moreover, we discuss some solutions of quantum mechanics and their meaning. Further, we research the entangled state of neurobiology by the extensive quantum method and the nonlinear theory. New experiments shown that the quantum entangled state should be a new fifth interaction, for its verification neuroscience will possibly take a very important role
