Abstract

ABSTRACT: Deep Brain Stimulation (DBS) is a medical-practical method and has been applied to solve many medical complications. Animal usage as sensors and actuators, mind-controlled machines, and animal navigation are some of the non-medical DBS applications. One of the brain areas used in ratbot navigation is the Ventral Posteromedial Nucleus (VPM), which creates non-volunteer head rotation. Rat training by water/food restriction can be used to create forward movement. In this study, a combination of VPM stimulation and water/food restriction has been employed to establish a complete navigation system. Five rats responded to VPM stimulations. However, with three of them, rats rotated to the same direction after the stimulations of either VPM side of the brain. Two rats rotated bilaterally, proportionate to the VPM stimulation side. These two rats were trained in a T-shape maze and became ratbots. The results of the 3-session test showed that their navigation performances were 96% and 86%, respectively. These ratbots are suitable for navigational purposes and are ready to complete the missions that are dangerous or impossible for humans. Graphical Abstract: uf0001
