Name:

    testsuite::test_hh_phaseplane - sli script for hh_psc_alpha model

Synopsis:

    (test_hh_phaseplane) run -> 'phaseplane.txt' & 'AP.txt'

Description:

      test_hh_phaseplane makes a numerical phase-plane analysis of the Hodgkin-Huxley neuron
      (iaf_psc_alpha). Dynamics is investigated in the V-n space (see remark below). A constant
      DC can be specified  and its influence on the nullclines can be studied.
      Results are written into two files. 'phaseplane.txt' contains the phase-plane data as a
      vector field and 'AP.txt' the trace of a single action potential as one possible
      numerical solution in the vector field. The data files are used in the matlab-script hh_phaseplane.m

      REMARK
      To make the two-dimensional analysis possible, the (four-dimensional)
      Hodgkin-Huxley formalism needs to be artificially reduced to two dimensions,
      in this case by 'clamping' the two other variables, m an h, to
      constant values (m_eq and h_eq).
