Development of a Stereotaxic Device for Low Impact Implantation of Neural Constructs or Pieces of Neural Tissues into the Mammalian Brain

Schematic illustration of the trajectory followed by the needle used to test the mechanical resistance of the rat brain. A fresh, postmortem rat brain was affixed to an ElectroForce device and a probe lowered at 0.25 mm/s to measure the mechanical resistance along the full length of the nigrostriatal pathway.
