Abstract: Temporal Interference (TI) stimulation enables deep brain targeting, yet precise optimization tools for mouse models remain limited. We developed a computational optimization tool integrating mouse head modeling with the optimization algorithm to optimize stimulation strategies for predefined target regions. By balancing target intensity and spatial focality, the optimized strategy significantly outperformed empirical baselines. For the CA3-CA1 target, it achieved a 7-fold intensity increase (10.29 vs. 2.89 V/m) under iso-focality conditions. Conversely, for the Dentate Gyrus, it improved spatial confinement ($r_{0.5}$ reduced from 3.99 to 3.54 mm) while maintaining comparable intensity. Cross-model validation on a standardized Sim4Life phantom further confirmed the framework's robustness. This approach offers a powerful tool for enhancing the precision and reproducibility of preclinical TI stimulation studies.
