Fig. 2. Two representative examples of paired-pulse facilitation. (A) An
unidentified alpha lobe-extrinsic neuron. The value for 20 ms is significantly
different from all other values (*P<0.01, post
hoc test, main effect: F=5.66, d.f.=3,
*P<0.01, N=45, values are means ±
S.D.). (B) A PE1 neuron. The value for 15 ms is significantly
different from all other values (P<0.001, post hoc test,
main effect: F=13.27, d.f.=3, *P<0.001,
N=28). The ordinate gives the number of spikes elicited by a single
stimulus. The abscissa gives the interval (
t) between the two
stimuli in the paired-pulse protocol. (C) Spike trains from the PE1 neuron in
B. (D) Spike train from a different PE1 neuron, which was stimulated with
higher-pulse currents eliciting more spikes per stimulus. The stimulus
artefacts mark the test pulses.
