In this study, we have investigated the mathematical components of the Dirac equation in curved spacetime and how they can be applied to the analysis of neutrino oscillations. More specifically, we have developed a method for calculating the phase shift in flavor neutrino oscillations by utilizing a Taylor series expansion of the action that takes into account ?m4orders. In addition, we have used this method to assess how the phase difference in neutrino mass eigenstates changes according to the gravitational field described by the Johannsen spacetime.

Humans and animals use the classic five senses-sight, hearing, touch, smell, and taste-to detect and monitor their environment, with the sense of position and movement often referred to as the sixth sense. The perception of external signals through the senses is essential to an organism’s survival, transmitting signals to the central nervous system(CNS) and prompting physiological changes in other biological systems. In addition to the direct effects of sense-induced mediators in the brain,
