1.43 2003 NEURON 4.3
Netscape 4.7
NIA 2003
  1. Added speed adjustment slider to the RunControl panel of all tutorials involving moving simulations.

    Important: In The Partial Demyelination Tutorial this bar must be kept at its fastest setting or the tutorial will not work as described.

  2. Separation of Mac and PC files in the file structure
1.01 2001 NEURON 4.2
Netscape 4.7
NIA 2000
  • Mylenated Axon Tutorial:
    Under "Measure conduction velocity and determine how the degree of myelination affects velocity":
    Corrected sentence: "As you add wraps, the capacitance is reduced to 0.5 uF/cm^2 with one wrap, to 0.333 uF/cm^2 with two wraps, etc., since the net capacitance of capacitors in series is the recriprocal of the sum of their reciprocals."
  • Passive Axon Tutorial:
    Under "How does the length constant change with axon diameter?":
    "Run the simulation." The equations on the page linked to "twice as large" have been corrected.
  • Synaptic Integration Tutorial:
    Under "Generate EPSPs in the dendrites and observe where the spike initiates":
    In the linked text to "Why is it so steep?" the value "thousandfold" has been corrected to "hundredfold."
