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

Figure 8

Characteristic friction profiles measured from the ElectroForce needle inserted into the brain phantom made from 3% (left scale) and 2% (right scale) gelatine solution. Note that the range of mechanical resistance is much smoother (in comparison to the rat brain) and that the resistance shown by 2% gels more closely matches those seen with the rat brain specimen (Figure 7).
