Dendritic membrane properties of CA1 pyramidal neurons
| Rat | Vm (mV) | Rinω (M&OHgr;) | Spike ampl (mV) | Spike width (msec) | Spike boosting (%) | F-dep prop (%) |
|---|---|---|---|---|---|---|
| SP (4) | -69 ± 2 | 28 ± 4* | 41 ± 5 | 1.4 ± 0.02* | 186 ± 12 | 58 ± 4 |
| Control (4) | -71 ± 1 | 40 ± 2 | 42 ± 4 | 2.4 ± 0.02 | 190 ± 20 | 60 ± 4 |
Dendritic recordings from 250-275 μm distant to soma. Vm′ Resting membrane potential; Rin′ input resistance; Spike, dendritic action potential; ampl, amplitude from Vm′ width at half-maximum amplitude; boosting is increase in spike amplitude when paired with a 10-15 mV dendritic depolarization; F-dep prop, frequency dependent propagation as the amplitude of 10th spike in a train divided by the amplitude of the first spike for 30 Hz antidromic stimulation. *p<0.01.
