Cabling Equations

• If you think of an axon (or a dendrite) as a one dimensional cable, you can model a neuron as a series of cables.
• The electrical flow with a cable from an adjacent cable can then be easily calculated.
• You could do this with input from a synapse (electrical or chemical).
• You could do this from an electrode.
• There are a lot of good simulators for this.
• As with most computer science, the algorithms continue to improve.
• Could it be done with 2D cables or 3D shapes? What happens with the soma?
• Is myelination modelled?
• Why is it important?
• Can a neuron be accurately modelled at the ms level?
