In the Wikipedia article on dendritic spikes I read:
In the hippocampus, the CA1 neurons contain two distinctive regions that receive excitatory synaptic inputs: the perforant path (PP) through the apical dendritic tuft (500-750 μm from soma) and the Schaffer-collateral (SC) through the basal and apical dendrites (250-500 μm from soma).
I wonder how the distinctiveness of these two regions does appear when plotting the number of synapses as a function of the distance to the soma:
More like the gray, or more like the red, or more like the green curve? Or which other?
