AdEx cells¶
- class arbor.adex_cell¶
An adaptive exponential cell.
- adex_cell(source, target)¶
Constructor: assigns the label
sourceto the single built-in source on the cell; and assigns the labeltargetto the single built-in target on the cell.
- source¶
The label of the single built-in source on the cell. Used for forming connections from the cell in the
arbor.recipeby creating aarbor.connection.
- target¶
The label of the single built-in target on the cell. Used for forming connections to the cell in the
arbor.recipeby creating aarbor.connection.
- V_th¶
Firing threshold \(V_\mathrm{th} = -20\,mV\) [mV].
- C_m¶
Membrane capacitance \(C_\mathrm{m} = 0.28\,nF\) [nF].
- E_L¶
Resting potential \(E_\mathrm{L} = -70\,mV\) [mV]
- E_R¶
Reset potential \(E_\mathrm{R} = -70\,mV\) [mV].
- V_m¶
Initial value of the Membrane potential \(V_\mathrm{m} = -70\,mV\) [mV].
- t_ref¶
Refractory period \(t_\mathrm{ref} = 2.5\,ms\) [ms].
- g¶
Leak conductivity \(g = 0.03\,mu S\) [uS].
- w¶
\(w\) initial value \(w = 0\,mA\) [nA].
- tau¶
\(w\) decaying constant \(\tau = 144\,ms\) [ms].
- a¶
\(w\) dynamics \(a = 0.004\,\mu S\) [uS].
