Abstract
This paper is concerned with synaptic coding when inputs to a
neuron change over time. Experiments were performed on a living and
simulated embodiment of a prototypical inhibitory synapse. These were
used to test a simple model composed of a fixed delay preceding a
nonlinear encoder. Based on these results, we present a qualitative
model for phenomena previously observed in the living preparation,
including hysteresis and dependence of discharge regularity on rate of
change of presynaptic spike rate. As change is the rule rather than the
exception in nature, understanding neurons responses to nonstationarity
is essential for understanding their function
