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

Figure 7

Characteristic friction profiles measured from the ElectroForce needle inserted into the rat brain along the approximate path linking the striatum to substantia nigra. Note the range of mechanical resistance varies as the probe is lowered. This is due to the needle interacting with different densities of tissues (i.e., grey and white matter) as it probes through the brain.
