Propagation illustrated here in branch 1 for the soma (red), the uniform (blue) and the distal (magenta) distribution. (A) Backpropagating, regular APs shown at the soma (point of origin) and at selected locations along a single dendritic branch. Trains of regular APs were generated by a prolonged stimulus protocol ( for 1000 ms) to the soma, and showed close-ups of the last AP in the train. (B) Ca²⁺-spikes shown at the soma and at selected locations along a single dendritic branch for selected distributions. Ca²⁺-spikes were evoked by a brief stimulus protocol ( for 10 ms), and with Na⁺-conductances set to 0 to suppress AP firing. Curves were graded from dark colours (close to the soma) to light colours (far from the soma).
