Differential polarization of cortical pyramidal neuron dendrites through weak extracellular fields
Fig 9
While regenerative currents increase the cell sensitivity to low frequency fields, restorative currents decrease it and induce a resonance.
We consider a neuron model which includes solely a leak conductance and a single uniformly distributed quasi-active channel (QA). The plots display the cell’s sensitivity (in mV/(V/m)) to AC fields at different location in case of restorative (blue, μ* = 2), passive (black, μ* = 0) and regenerative (red, μ* = −1) quasi-active currents.
