In NEURON simulator, is there an easier way to list properties of a section other than iterating over each property individually?

There is the psection() method. Once the section of interest is push()ed. Typing psection() or, from Python, h.psection(sec=your_section) will produce the following example result:

>>> h.psection(sec=h.Granule[0].soma)

Granule[0].soma { nseg=1  L=8  Ra=80
    /*location 0 attached to cell 5*/
    /* First segment only */
    insert morphology { diam=8}
    insert capacitance { cm=4}
    insert pas { g_pas=0 e_pas=-65}
    insert kamt { gbar_kamt=0}
    insert nax { sh_nax=15 gbar_nax=0}
    insert na_ion { ena=60}
    insert kdrmt { gbar_kdrmt=0}
    insert k_ion { ek=-90}
    insert Exp2Syn { tau1=5 tau2=50 e=0}
    insert IClamp { del=50 dur=200 amp=0.09}
}

    Pushing a section is generally bad form because so many things can be affected by the section stack. It's better to use the sec= keyword argument which constrains the effects, e.g. h.psection(sec=h.Granule[0].soma); in NEURON 7.6+, there's also a psection method that returns a data structure that your code can analyze. – ramcdougal May 09 '19 at 16:25

If you are using the NEURON gui, you could also find section properties in the NEURON's control menu:

Tools-> Model View

This's will open a ModelView window which has section and segment details such as:

  • Type of cells: real cells/ artificial cells
  • NetCon objects
  • LinearMechanisms objects
  • Density Mechanisms
  • Point Processes

If you click on each property, a drop-down menu appears showing the details of the property selected

You could also view the structure of the model if you click on the cell type (real/artificial cells)
