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.
