Your company has just developed an electrode to be implanted in the brain to measure
  electrical activity in terms of electrical current. After implantation in a rat brain in vivo, you
  record the following results as indicated by the solid line (A) below.
 
 
  a. Formulate a mechanism to explain these observations.
 

  b. After implanting an electrode with its surface modified by covalent attachment of
  poly(ethylene glycol) in the rat brain, you obtain the data shown by the dashed line above
  (line B). Why does the surface modification of the electrode alter the results? Would you
  recommend marketing the surface modified electrode?
