The nicotinic postsynaptic currents in thereticularis thalamus are insensitive to the replacement of calcium by magnesium or by Cd2+ or Ni2+treatment. A, Examples of current traces fromreticularis thalamus neurons; 10 μm DMPP is applied in control condition, after the replacement of calcium by magnesium, or after the addition of Cd2+ or Ni2+. B, Average of the responses to DMPP after the different treatments and normalization to the control responses. The number of points averaged is (from theleft to the right bar) 4, 6, 3.
