Jitter Analysis of Timing Codes for Neurons with Descending Action Potential Thresholds

We analyze three sources of timing jitter for (differential) time of arrival estimation for successive spikes arriving at a biological synapse. The dominant source of this jitter is believed to occur during spike generation. Other jitters introduced by propagation and estimation for time-of-arrival are on the order of 10 microseconds. We also obtain and compare several forms of the threshold curve when different assumptions about its form or error properties are imposed
