Figure 3. — Dendritic propagation of APs is active and requires voltage-gated sodium channels but not calcium channels. A, Somatic (bottom) and dendritic (top; 230 μm from the soma) recordings of somatically generated APs before, during, and after local dendritic application of TTX (1 μm). Inset, Superimposed traces. B, Dendritic recording (205 μm from the soma) of antidromically generated APs before (left), during (middle), and after (right) bath application of cadmium (200 μm). Note the increased amplitude and base-width at 15% amplitude. Inset, Superimposed traces.
