As (d_{2}) tends to zero, the boundary spike shifts to the boundary with its magnitude increases.
Similarly as in Figure 3, we show in Figure 8 that when (d_{2}) becomes small, the boundary spike shifts to the corner and its magnitude increases.
This effect is very clearly seen when the interval between the new and the old, trailing spike is less than 50 ms. The spike shifting effect results in a discontinuity in the conductance-spike timing relationship, i.e. a sudden jump from the course of the monoexponential (see arrows in Fig. 3A2, A3).
b Spike time shifting: Independent noise leads to shifting of spikes by weakly modulating the integrand in Eq. (16) independently for both neurons, but no spikes are added or deleted.
The phase response curve (PRC) is a measure of the spike time shift caused by perturbations of the membrane potential as a function of the phase of the spike cycle of a neuron.
The intrinsic properties can be revealed by the phase response curve (PRC) [1], defined as the spike time shift caused by a small perturbation of the membrane potential as a function of the time of the perturbation during the spike cycle.
Fifteen years after an energy crisis, caused partly by deregulation and market manipulation, brought blackouts and price spikes, the shift has been remarkably smooth, many analysts say.
(C ) When inhibition was disrupted by introduction of high Cl−, the peak spike rate shifted from −18 ± 11 ms before the leading edge reached the centre to 209 ± 26 ms after the centre was traversed (n = 6; p = 0.0002).
The second was a test for a significant peak in the peri-stimulus time histogram (PSTH) using a bootstrap analysis: over a 2 s window (1 s before stimulus onset to 1 s after stimulus onset) spikes were shifted circularly, where the extent of the shifts were drawn from a uniform distribution of ±1 s.
There were no significant differences in residual fluorescein beads among Group B, Group C, Group D, and Group E. Removal of OVD from behind the IOL is critical to prevent IOP spikes, avoid shifts in centration of IOL as well as capsular block syndromes, and ensure sterility in the eye after surgery.
