increase in stimulus intensity on the nerve response locked to the rising phase of a
periodic stimulus. In ( A ) the lower picture shows two action potentials evoked by
the stimulus. Above is a dot display where consecutive sweeps are displayed above
each other, each spike being represented by a bright dot. There is considerable
variation in the time of occurrence of the first spike as is also evident in the time
histogram above. In ( B ) 4-5 spikes occur with shorter delay and regular timing
( L o b b t a ) .
