Removal of the Dendrite Decreases the Biphasic Nature of the Spike Rise

Figure 13. Removal of the dendrite from the model reduces but does not eliminate the biphasic nature or the noisiness of action potentials in the soma. This reduction in the biphasic nature results from the loss of the capacitative and conductance load placed on the soma by the dendrite. Increasing the capacitance of the soma reverses this effect (not shown)
