The Role of Ongoing Dendritic Oscillations in Single-Neuron Dynamics
Figure 7
Changing the phase-locked solution of dendritic oscillators with external input and its detection with an excitable soma.
A: Schematic drawing showing the configuration of two dendritic Morris-Lecar type II oscillators and a spike-generating soma (see Methods). All are separated by a passive cable with electrotonic length and
ms, with
S cm
. B: From top to bottom are shown the inputs to the two dendritic oscillators, the phase difference dynamics (red) and somatic firing rate (black), and the somatic membrane potential
(blue) with the spike threshold (dotted black line). Note that the spikes have been cut off in order to show the subthreshold membrane potential. C–D: Bifurcation diagrams describing the phase-locked solutions up to
seconds (C, see also figure 4C) and after
seconds (D) with dotted line at
giving the electrotonic distance between the dendritic oscillators.
