Technically, a single final spike can be fired if γ rises above −b and then falls below it, however, so the upper bound here is not precise.
The ISI during an IPSP was simply the interval between the final spike prior to delivery of an eIPSP and the first spike following recovery from inhibition.
President Warren G. Harding visited Fairbanks in 1923 as part of a trip to hammer in the ceremonial final spike of the railroad at Nenana.
Yet despite it all, the final spike was hammered into place at Promontory Point, Utah, in 1869, linking the nation and heralding a new burst of prosperity.
In 1869, when the final spike of transcontinental railroad was driven into the ground, that happy act of union took place in Promontory, Utah.
Next, we estimate δ ( g ) for the final spike fired, which we call δ f.
We denote the total number of spikes by n and estimate the final spike time T n for any fixed β by t ¯ , which gives ∑ i = 1 n C i = β t ¯ → ∞ as β → ∞.
The shaded region indicates the set where θ ′ < 0. δ 2 is the change in g as θ evolves from −π to π for the firing of the neuron's final spike.
To do this, we assume that when the final spike is fired, the trajectory reaches the lower bound on the g values that can yield a spike, namely the point of intersection of the v-nullcline and { v = 1 }, at which g = g 0 + = ( 1 − I ) / ( E − 1 ).
The final spike ceremony for the 428 mile long line from Richmond to the Ohio River was held on January 29 , 1873 at Hawk's Nest railroad bridge in the New River Valley, near the town of Ansted in Fayette County, West Virginia.
