Morphology of neurons filled with Lucifer yellow during electrical recordings
| High CF (n = 8)a | Middle CF (n = 6) | Low CF (n = 5) | |
|---|---|---|---|
| Somatic surface area (μm2)b | 581.8 ± 37.6 | 620.2 ± 45.4 | 813.1 ± 118.8 |
| Number of primary dendritesc | 19.5 ± 1.3 | 16.7 ± 1.5 | 4.2 ± 0.2 |
| Dendritic length (μm)c | 8.9 ± 1.3 | 20.9 ± 5.1 | 155.6 ± 29.4 |
| Dendritic width (μm)b | 1.4 ± 0.1 | 1.6 ± 0.1 | 1.9 ± 0.1 |
| Simulated capacitance (pF)d | 13.4 | 23.7 | 47.1 |
↵ a Number of cells is indicated in parentheses in this table and in Table 2.
↵ b Difference was significant between high- and low-CF neurons (p < 0.05) but was not significant between the other two pairs (p > 0.1).
↵ c Difference was significant between low-CF neurons and neurons in the other two regions (p < 0.01) but was not significant between high- and middle-CF neurons (p > 0.1).
↵ d Input capacitance was simulated from the somatic surface area and the dendritic surface area using the specific capacitance of 1 μF/cm2. The dendritic surface area was estimated as the simple integration of the length and the width times the dendritic number.
