The distinct membrane properties of CPn versus COM neurons at the soma extend to the dendrites. A, Simultaneous somatic and dendritic whole-cell recordings were made from CPn-type and COM-type neurons at RMP. B, Voltage was measured at the soma and dendrite in response to local current injection. Sample voltage responses are shown at left. In CPn neurons, the dendrites had a lower RN and more rebound compared with the soma. In COM neurons, RN was high at both the soma and dendrite, and there was a little more rebound at the dendrite compared with the soma. C, In CPn neurons, the dendrite was more resonant than the soma, whereas in COM neurons the soma and dendrite were both nonresonant. Sample voltage responses and ZAPs to a chirp stimulus are shown for each cell type. *p < 0.01 (paired t test).
