Command: testsuite::test_hh_phaseplane

Synopsis

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

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).
