.. currentmodule:: arbor

.. py:class:: adex_cell

    An adaptive exponential cell.

    .. function:: adex_cell(source, target)

        Constructor: assigns the label ``source`` to the single built-in source on the cell; and assigns the
        label ``target`` to the single built-in target on the cell.

    .. attribute:: source

        The label of the single built-in source on the cell. Used for forming connections from the cell in the
        :py:class:`arbor.recipe` by creating a :py:class:`arbor.connection`.

    .. attribute:: target

        The label of the single built-in target on the cell. Used for forming connections to the cell in the
        :py:class:`arbor.recipe` by creating a :py:class:`arbor.connection`.

    .. attribute:: V_th

        Firing threshold :math:`V_\mathrm{th} = -20\,mV` [mV].

    .. attribute:: C_m

        Membrane capacitance :math:`C_\mathrm{m} = 0.28\,nF` [nF].

    .. attribute:: E_L

        Resting potential :math:`E_\mathrm{L} = -70\,mV` [mV]

    .. attribute:: E_R

        Reset potential :math:`E_\mathrm{R} = -70\,mV`  [mV].

    .. attribute:: V_m

        Initial value of the Membrane potential :math:`V_\mathrm{m} = -70\,mV`  [mV].

    .. attribute:: t_ref

        Refractory period :math:`t_\mathrm{ref} = 2.5\,ms` [ms].

    .. attribute:: g

       Leak conductivity :math:`g = 0.03\,mu S` [uS].

    .. attribute:: w

        :math:`w` initial value :math:`w = 0\,mA` [nA].

    .. attribute:: tau

        :math:`w` decaying constant :math:`\tau = 144\,ms` [ms].

    .. attribute:: a

        :math:`w` dynamics :math:`a = 0.004\,\mu S` [uS].

              
    .. attribute:: b

       Increase in :math:`w` after emitted spike :math:`b = 0.08\,nA` [nA]
