Figure 1. NBP treatment improved the behavioral deficits of rats with POCD. (A) Trajectory plots of one randomly selected rat from each of the five groups. One day before the operation, all rats could find a fixed platform within 50 seconds, and there was no substantial variation between the groups. (B) Trajectory plots of one rat were randomly selected from each of the five groups one day after the operation. (C) After the fracture model was established, we observed that a significantly longer time was required to reach the platform by rats in groups α and β in comparison to the ones in groups γ, δ, and ε. (D). Time for each rat to reach the platform after the operation.
