The Role of Ongoing Dendritic Oscillations in Single-Neuron Dynamics
Figure 2
A: Parameter as a function of the electrotonic distance
between the oscillators when the cable is passive (black) or with a regenerative (green) or a restorative (red) active current. The oscillator frequency is 8 Hz (dotted line in panel B). The membrane time constant of the connecting dendrite is
ms. The parameters for the active currents were determined for
(restorative) and
(regenerative) which are described in the Methods (see Equation 29). The current parameters when linearized around
mV are
,
and
ms for the regenerative current, and
,
and
ms for the restorative current, using the conductance densities given in the Methods. B:
as a function of the frequency of the oscillator (in Hz). The oscillators are separated by a cable with electrotonic length
(dotted line in panel A) for the same three conditions as in panel A.
